Sandisk 32GB too slow!

Just purchased 32GB Sandisk micro SD. To my knowledge Sandisk has only one 32GB micro SD card and it's a class 2. I have had same, but in 8GB capacity. From time to time I copy/backup folders to external SD: Navionics, Epocrates, and TitaniumBackup...up to 460MB. On 8GB it would take a minute or two each, but with new 32GB it takes forever. Both class 2; same manufacturer, but smaller one much faster. Any suggestions?

Class it up! Try a class 4 or 6.
nvm: I read later that you mentioned you get a faster speed on a Class 2 8gig than on a Class 2 32 gig. I just need coffee. Ignore my comment

I have a Sandisk 32gb Class 2... and it's slooooow. So I tried a 32GB Class 4, and it's still equally slow. I'm beginning to think it's the device, not the memory card. I'm getting annoyed with how much just having a memory card in the slot slows down the phone. I may just tolerate the internal 16gb and stop using an "external SD" because it's gotten super annoying waiting for it to scan all the time.

I have an adata class 4 32gb and its pretty good copying to and from. I got it from a quality retailer. If you didnt get it from a quality retailer, TEST it with h2testw app on the pc and make sure its real. It will take a long time to test it. Writing will go quick and you wont see any errors, but reading and verifying the writen data will take a lot longer and thats where the errors will show if its truly not a legitimate card.
I got a couple of fakes off ebay that i got refunded for, but these people sell thousands of these things on there and alot of people get fooled because they seem to work fine, UNTIL down the road when you cant read the data and lose a ton of stuff.
If you test it and get no errors on the reading side, you got a slow card and thats all there is to it. Its not the phone becuase it works fine with cards for most everyone. Not many complaints showing up

Mine's a legitimate card, that much I know. Best Buy doesn't sell china-models, haha

Correction. It's a Class 4 that I bought from Staples.
Sandisk technical chat was a joke and commented:"Well there is no guaranteed read and write speed. Still you can try formatting it with a tool called HP Tool"
My response:"Your comment could be construed as a copout. I believe everyone should have the guarantee that when same manufacturer produces a product and one is classed to have double the transfer capability ...... it should perform as such"
Sandisk chat :"I understand but we do not have any read and write speed on micro SDHC card"

Kudos to you for challenging them... Unfortunately the world is becoming more and more of a marketing-reality. Something can be marketed as anything. AT&T decided they'd rather call their 3G a "4G network" rather than update to 4G... Sandisk decided to call their Class 4 a "Class 4" without any sort of technical evidence of it complying with the standard... and who's going to stand up to them, just like who's going to stand up to AT&T? Very sad state we've gotten to.

Wait, are you saying that if one removes the external SD card that no scanning takes place?!?! If so that bish will be out of there in a hot minute! 2GB isn't worth the headache.

Yes class 2 is like the 3200rpm hard disk. Back in 1990's. Get class 6. I have class 10 it's very fast.

Is the Infuse able to take advantage of the Class 10? I thought I read somewhere anything above Class 6 reads the same on modern smartphones. Anyone have real world experience using infuse with class 2 vs 6 vs 10?

Tested it and it came back 10.44 Mbs read/4.66 Mbs write. This was after formatting it with HP Tool. That is within spec for Class 4, but seemed just too slow. I'll try to transfer same files again and share results.

Does PNY make Class 10 16 or 32gb cards? In searching on Amazon 32gb Micro SD Class 10, I'm seeing Lexar, and Patriot. The Patriot gets mediocre reviews saying that it dies frequently, and is incompatible with many devices. I'm thinking of buying the Lexar, but I still haven't seen anyone post any better read\write speeds, so I'm wondering if the Samsung can even read\write faster than class 4.

PNY 16 GB class 10 at Costco.com $29.99

Aww, I just think I'd regret only going 16GB... if there are 32GB available, I think I'd be regretting it in a week if I bought a 16GB.

Wanting to buy @ Amazon... I have $300 in gift cards on Amazon, so need something I can order from them. Not a fan of Newegg as they charge Tax in CA, and their "standard" shipping is slooooow (up to 10 days the last couple orders). I have Amazon Prime free 2 day shipping, and no tax here in CA, so I'm trying to stick with them.

Droid Charge VZW's most Expensive Phone?

Why is the Droid Chrage currently the most expensive handset? I mean, it's a suped-up version of the Fascinate (a $50 handset). It doesn't even run GB @ stock right now.
Anyone have some thoughts about this strange overpricing?
Thanks for all the replies! Very interesting!

Its the premium cost for LTE. that plus the screen
Sent from my SCH-I510 using XDA Premium App

It's partly because of 4G, but not exclusively, because there are two less expensive 4G devices -- the $249 Thunderbolt and $199 Revolution. That said, when compared to those two phones, the price difference can be explained (I hesitate to use the word "justified") to some extent.
First, there's the Super AMOLED Plus screen. The Thunderbolt and Revolution run regular LCDs.
Then, and in many ways this is the most important, there's battery life. The Charge's life may not be great compared to 3G devices, but compared to the Thunderbolt or Revolution it has a big advantage.
Lastly, while all three have a single-core 1Ghz processor, the Hummingbird still takes the lead over the Snapdragon 8655 used in the other two devices (though the Thunderbolt does have more RAM).
The Revolution falls behind still with a 5MP camera (vs. 8) and a 16GB SD card (vs. 32).

Isn't the screen similar to the Fascinate?
Also, the charge is only $70 at Amazon. Now I fell ripped off for paying $130 for it just before they discontinued unlimited data. Of course, if it weren't for that I would've waited and bought a different phone.

Are you sure about that? I was getting 1600+ quadrant on stock 2.2 on the Motorola Triumph (which uses a 8655).

Only to an extent. The Fasinate has a Super AMOLED screen while the Charge has the newer Super AMOLED Plus, and while that may not sound like much there are some pretty major differences between the two. The original used a horrible pixel matrix (PenTile) which lead to a very noticeable text graininess and pixelation.
The Plus screen uses a regular arrangement, and as such looks drastically sharper despite having a lower pixel density from being .3 inches bigger. I can personally attest to the difference as a former Fascinate owner... it's a big, big step up.

For starters, Quadrant scores are entirely meaningless when used to compare different devices. The tests it runs are biased towards Snapdragons because they're optimized for floating-point operations, meaning arithmetic. But I don't think most people use their phones primarily to crunch numbers.
That said, the 8655's CPU core is in general slightly faster than the Hummingbird's, but not enough to be noticeable in daily usage, and when comparing SoCs it's also about the GPU... and that's where there's a big difference between the two. Here's the Hummingbird's PowerVR SGX540 GPU compared to the Snapdragon's Adreno 205:

I refer you to any Econ 101 textbook.
Stuff costs whatever the intersection of the supply and demand curves dictates.

The Charge at full retail is over $100 cheaper than the 16 gig iPhone at full retail and over $200 cheaper than the 32 gig.
The reason the Charge is so expensive is because there is no special data plan set up for it. At $299.99 there's still very little profit to be made by the stores because the phone itself costs the stores a lot of money to carry.
The iPhone has a special data plan set for it that pays out double than what the regular data plan does. Still, the cost of the phone for the store is so damn high that the iPhone still brings in ****ty profit.
4G phones are so expensive that VZW should add a special data plan for the stores that pays out more, so they can charge less for the phones.
Remember, if you go to a store and they try to get you to buy a Dinc2 or X2 or Droid 3 over any 4G phone, it's because the 4G phones are a profit nightmare.

That would be a terrible idea. If you're worried about the price of the phone, don't buy from a verizon store. Best buy mobile has the phone for $199.99 and I bet you could get it even cheaper on the internet.

Though you are completely right....that is the stupidest answer I have ever heard. A very douchebag response on your part, and you know it.
Though I don't know for sure I'm assuming the OP is a fascinate convert so he is probably puzzled why Verizon replaced the fascinate with a phone that costs 3x more. The screen is definitely better and 4G LTE has really surprised, never thought it was this fast!

I'm not saying to charge the customer more for the data. Apple data for 2gigs is still $30 a month.
What I'm saying is that VZW should give the stores more money for LTE data.

I glady paid $270 for my Charge considering the fact that 32GB micro SD cards still cost $70+
I'm surprised no one has mentioned this.

More like $50. I was impressed that I got a class 4 card with mine, though- every phone I've owned has come with a class 2 SD (as did my wife's Charge).

Some got lucky and got a C4 instead of a C2. Anyone know if you can go into a verizon store and swap it?
Sent from my Droid Charge running GummyFroyo 1.9.1

The speed rating (c2 c4 c6 etc...) is only for write speeds. Read speeds are the same I guess.
Anyway, I read that on another forum. So for reading (which is the primary interaction your phone will be have with the card probably 90% of the time if not higher), the speed rating of the card should not matter. I was just about to go get a C6 but then I found the information on another forum and had my hopes dashed.
Correct me if you can...

Just because 90% of the time you are reading from the SD card doesn't mean that the other 10% is allowed to be broken.
Case in point, 720p recording on my class 2 is not possible. An advertised, paid-for feature of my phone is unavailable to me. How is this okay, I ask you?

Generally, the cards with the faster write speed will also have a faster read speed. However, that can vary. I benchmarked the following 3 cards via ATTO:
1) Sandisk 32GB C4 mSDHC from the Thunderbolt
2) Sandisk 32GB C2 mSDHC that I had bought when I had my Touch Pro2
3) Samsung 32GB C2 mSDHC from the Droid Charge.
In terms of speed, the Sandisk C4 was by far the fastest in both read and write speed. Next in line was the Sandisk C2, which beat the Samsung C2 all around as well, but by a smaller margin.
This also proves that class isn't everything, brand can make a difference as well. The Samsung was bordering at even pulling true C2 speeds, whereas the Sandisk lived up to the claim with a good margin. Both of the Sandisk cards (C2 and C4) were really underrated, but that is a good thing.

In regard to the pricing- I think it was just to keep it in line with the iPhone's pricing. The 32GB model is $299, is it not? And the Charge is the competing Android flagship to the iPhone (debatable, perhaps, to those who prefer the Thunderbolt, but as a Droid branded phone it's certainly marketed as such).

Class 2 = 2 MB/s
Class 4 = 4 MB/s
Class 6 = 6 MB/s
Class 10 = 10 MB/s
So just think of transfer speeds, the bigger the files the longer it'll take. For example say I had a 4MB picture or file and I transfer it to the Class 4 SD card, it will take 1 second. If I had a 100MB file on a Class 10 it will take 10 seconds to transfer while on a Class 4 it will take 25 seconds. If waiting time doesnt bother you then Class speeds wont matter as much but if you do transfer a lot of files or media all the time then they're really important (HD videos etc...). It also helps if you like to update your phone with ROMs and data files frequently. Some of the files range up 200-300+MB in sizes so having a Class 10 will help in transfer speeds. So thats the only difference between the classes, they're guaranteed write speeds under ideal conditions.

You know, if you click links, you learn stuff!
Class 2 and 4 cards have better random access speed and random read/write than class 6 or 10 cards in general. To get higher sequential write speeds, manufacturers sacrifice the random access speeds. That's just how it is.
The best all around card I've ever found is Sandisk class 4.
My 32gb Sandisk class 4 outperforms any other class 10 or 2 32gb card I've tested in the random access and random read/write speeds. That's what's most important when using with WP7 or Android when using it for apps or OS files that need to be accessed quickly. Class 6 and 10 cards are setup to initialize the area of the card that is about to be used to make the sequential write/read quicker, but it takes extra time in the beginning to do the initialization. If your using the card where you need to access small bits of info from various parts of card quickly, you will do best with class 2 or 4.
Most people seem to assume that the higher the class, the better the card is for everything, but that's not how it is. Different purposes need different kinds of speed... cards with higher sequential speeds have lower random speeds.

If you try doing things on your own, you also learn stuff. Better stuff.
I use my SD card for storing files.
I back up my ROM to it.
I pull ROM's off it.
99% of the time I access my external SD card, it's to write a large file or read a large file.
So I guess my Class 10 SD card is faster than the best Class 4, 99% of the time for me. \
I've tested the times and measured the write times at least.

lol those are theoretical write speeds "sustained" (minimum meaning "at least")I posted, if I could paste links before I wouldve done it but I couldnt. Its not my fault that other companies rebrands their stuff so they don't have to make multiple models to save money. Yes companies do that too. And no when I think SATA6G i think Gigabits not gigabytes, if thats what you're thinking gigabytes then sorry bro.
I'm not giving wrong information you're just misinterpreting it because you don't understand it. I'm going based on the definition that they listed, not by benchmarks. If the benchmark shows that Class 6 outperforms Class 10 then thats awesome everyone should buy Class 6 then. But I'm not going to list that Class 6 performs 20MB/s and Class 10 performs 19MB/s... Like I said they're not all going to be the same because companies do that they will slap on whatever class to save money. The link you showed me click on it and read it, people will have various results how come the guy that bought 8 of the same memory got 22, 19 and 11MB/s on his results?
Speed Classes 2, 4, and 6 assert that the card supports the respective number of MB/s as a minimum sustained write speed for a card in a fragmented state. Class 10 asserts that the card supports 10 MB/s as a minimum non-fragmented sequential write speed.
http://www.sdcard.org/downloads/pls...ified_Specification_Ver_3.01_Final_100518.pdf
If you want to buy a lower class rating memory then thats up to you congrats you bought one! Just know that benchmarks are benchmarks just because they give you a big number doesn't mean its always better in real life scenarios. (Meaning most likely the card is empty when they do the benchmarks, not full).

You know what that means? "minimum" it doesnt say "maximum". Two different words. Anyways have fun with your purchase

lol those are theoretical write speeds "sustained" (minimum meaning "at least")I posted, if I could paste links before I wouldve done it but I couldnt. Its not my fault that other companies rebrands their stuff so they don't have to make multiple models to save money. Yes companies do that too. And no when I think SATA6G i think Gigabits not gigabytes, if thats what you're thinking gigabytes then sorry bro.
I'm not giving wrong information you're just misinterpreting it because you don't understand it. I'm going based on the definition that they listed, not by benchmarks. If the benchmark shows that Class 6 outperforms Class 10 then thats awesome everyone should buy Class 6 then. But I'm not going to list that Class 6 performs 20MB/s and Class 10 performs 19MB/s... Like I said they're not all going to be the same because companies do that they will slap on whatever class to save money. The link you showed me click on it and read it, people will have various results how come the guy that bought 8 of the same memory got 22, 19 and 11MB/s on his results?
Speed Classes 2, 4, and 6 assert that the card supports the respective number of MB/s as a minimum sustained write speed for a card in a fragmented state. Class 10 asserts that the card supports 10 MB/s as a minimum non-fragmented sequential write speed.

If you want to buy a lower class rating memory then thats up to you congrats you bought one! Just know that benchmarks are benchmarks just because they give you a big number doesn't mean its always better in real life scenarios. (Meaning most likely the card is empty when they do the benchmarks, not full).

It's ok, kryptos doesn't understand. I was enjoying that he was thinking his cards were faster. Oh well, now he knows.

Got one yesterday, thanks for the heads up

64GB microSD

Hello all,
Does anyone have a 64GB microSD card that's SanDisk or Samsung? If so what model (i.e. ultra, ultra plus, extreme, Pro, etc)? And what's the actual read/write speeds vs. what is printed on the packaging? This will help me, and hopefully others, buy what's necessary. I don't really see myself needing the quickest write speed this side of the Mississippi at 90MB/s but I'm also thinking 30MB/s isn't enough when prices are dropping so they can be had for $30/each.
Thanks!

Bought this one the day I got my M8. Not sure of the write speed as I use it for music and photo's and don't really worry about read/write speed. Is there an app to test that? I've never taken it out the phone as I don't have a need to.
When I got it it was on sale for like 25 bucks or something as an amazon deal of the day.
http://www.amazon.com/gp/product/B00I4ZMNY4/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

I've got the 64gb ultra in my m8 and the speeds are good. I copy and transfer files over a gb often and they take very little time. That's the 30 mb/s. I have the 64gb extreme pro in my Ricoh gr and its bad ass but not sure it's needed for this phone.

Yeah I'll be using it for music and photos as well @meest
Thanks @bill3508 I appreciate it. I'm thinking the Extreme Pro in a cell phone is overkill as well. I like to transfer 4-5GB at a time of music (I have a $#!? ton of music and like every genre when I'm at the gym).

Best price I could find. Just over the $35 free shipping level. I'm sure they did that intentionally. I will only buy cards from a retailer or manufacturers directly. Made a $20 mistake with China. At least my c/c company gave me the money back.

Bang for the $$ sd card

https://www.sandisk.com/home/memory-cards/microsd-cards/extreme-microsd
My moto x pure is on the way but Ive been searching out micro sd cards and this seems to be the best price/performance ratio I can find based on my limited understanding.
Can anyone state otherwise or have an alternative suggestion based on current market?

In my experience the biggest issue you will have is counterfeit cards I had 2 PNY cards of the 128 gb variety both supposedly fast cards neither were as fast as advertised they had decent read speeds but the write speeds were around 7MB/s or lower the Last sandisk card i had just quit working very abruptly. Since then i have stuck with G.Skill Sony and samsung cards the g.skill i have is very old and it is also slow the sony's i own preform adequately but the newer samsung cards i now swear by have really impressed me both reads and writes are blazing fast...

Im using this one, Read at 45 MB/s and Write at 18 MB/s. Its ok for me, dont know if will work good for you.

Lexar cards are pretty good just get them from a reputable company and be careful of Amazon as they are full of counterfeit cards.

I got this one for my X Pure. That said, I did get it at Best Buy last year on a sale for about $23 + tax. Pretty darn excellent performance except for the slow write speeds. Normally I wouldn't care about stuff like that but transferring a lot of videos into it can become a bit of a last question from Jeopardy, but completely stretched out.

got it
appears to be a legit card first and foremost uhs-1 u3 and 119gb useable.. Retail packaging ..Atto shows read and write just under 20 mb s with included adapter in my built in card reader.. no where near the 90 mb/60 mb potential but to be expected in standard usb card reader. ill see how it does with 4k video on the moto x

I should mention i tested the samsung cards in my phone and laptop and the write speeds were around 40 MB/s in both read was in the 85-90MB/s As far as my phone goes i did not see much change but when i move things to and from the phone it is a lot faster

I got the same Samsung card but from Amazon directly instead of a 3rd party seller, only paid $33 for it a few months ago, but I see the price has gone up since then. Hasn't made my phone explode as of yet :laugh::laugh::laugh:

I also have a 64gb PNY that I've had no issues with that I bought at a local box store, everything benched within (or close enough to) advertised parameters.

Got my moto and the app I found to test in phone shows around 40 mb write and 80 mb read... Not bad, Although this is the same or slower than your reported speeds for the samsung but was this the evo Plus? JJust asking for the benefit of others mostly it depends whats available for the $ AT THE TIME. It would be interesting though if the evo plus performed better than the sandisk UHS-1 u3 rated card

Mine was NOT the Evo Plus card.

Well, if anyone is looking at a decent deal on a 128gb card, B+H has this Samsung 128 GB card cheap: https://www.bhphotovideo.com/c/prod...g_mb_mc128da_am_128gb_evo_micosdxc_class.html
best buy has it on sale as well, but for $60: http://www.bestbuy.com/site/samsung...=4568502&productCategoryId=pcmcat351600050002
i just ordered one from B+H for my MXPE. (32gb/32gb just isn't cutting it)

UPDATE: the $40 at B&H was well worth...

You really must buy these things on Black Friday - Cyber Monday weekend. It is the cheapest time for flash memory and downloadable software ( antivirus upgrades, photo software, etc etc)
This card dropped to $ 99 , then $49. I grabbed for all of our Androids, and have 2 left over for other uses that may come up. Even if $49.99 is too expensive, they had the 64gb for $25.
http://www.bestbuy.com/site/sandisk...-class-10-memory-card/5110501.p?skuId=5110501
..It is the uhs-I class 3 as photo shows.. not 10 as description says. Best Buy listings have several errors in wrong photo in correct listing, and vice versa.
( Btw... The Extreme Pro is now their UHS-II products.. Which you would get no use out of..And one test I saw said it could run slower in a uhs-I device..And those did not drop as much in price, if at all for the holiday sales.)

I'll chime in and say that it depends on if you're planning on doing adoptable storage (or 50/50 or 75/25 percent externalSD/adoptable space like I do), I have your answer right here.
https://www.amazon.com/gp/product/B01273JZMG/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1
You MUST go with the Samsung EVO+. This recommendation is valid as of mid-2016, that's when I bought mine, so perhaps something has come out since then that's faster.
But assuming not, which is probably the case, I did my research and the Evo+ is the only card on the market that can consistently hit the highest RANDOM r/w speeds. That's important because many cards will advertise their high R/W speeds but they are referring to the sequential speeds, aka writing a block of sequential data in a linear fashion to the card, aka image or video data. Adoptable storage means reading from many separate sectors of the card (where different apps' data is stored) and writing back to them, all at as high a speed as possible to maintain interactivity with your finger, which will always be bottlenecked compared to a predictable sequential write.
Trust me, I didn't think it mattered when I bought a 128GB PNY card for relatively cheap (not a fake one either, I didn't want to take chances so I bought legit off Amazon), set it up in adoptable storage and then balked as Facebook and Snapchat would hang for full seconds at a time, making the apps all but completely unusable. And this was a pretty highly-reviewed card, but then again most of the cards you'll find on the front page of an Amazon search are too. I did some googling and while I can't remember my sources, if you look around you'll find that the Evo+ is kind of in a league of its own, as it's the most recent iteration of Samsung's line and is essentially the fastest card available right now. I returned the PNY and splurged on a 64gb Evo+, dropping some storage space quantity in favor of quality. While apps aren't still quite as PERFECTly responsive as on the internal storage, it's a HELL of a lot better than with the other card, like an order of magnitude better, and in the 6+ months I've been using it I actually haven't noticed the infinitesimally small lag which makes it great in my book.
So, if you are only planning on using the card to take pictures and video, music, or other static data you'll probably be ok with any decent cheap card. But if you're even thinking of setting up adopted storage, or honestly even if you aren't, I'd recommend going with the most blazingly fast card you can get because otherwise you're just going to have a bad time. This is one of those things where cutting corners even a little bit brings down the whole house of cards.
