I live in China and I'm having some trouble to find a good microsd.
First thing, prices vary wildly, it might be because some are counterfeits and or lower speed (something about the class).
So does one go about buying a good microsd card?
Which class is faster?
Is branded better? How to make sure it's not a counterfeit?
I would order one online if you can. There are different classes for Micro SD cards. The higher the class, the faster the read/write speeds are. I believe the classes go as follows : 2, 4, 6, 10

I'm live in Silicon Valley in Northern California, home to SanDisk, Patriot, and other big makers of SD cards. I come across tons of real and fake SD cards all the time.
First thing I look for is the brand name. The packing that the SD card usually displayed the brand name as well as it's labeled on the SD card itself. Also, brands like SanDisk have the model number of each card on the packaging, which you can reference online prior to purchase.
I have a Patriot 16 GB Class 10 Micro SD card that I purchased from Amazon.com. - They have a policy against counterfeit items and you can get a refund if one is sold to you. Another website to look at to find good deals on SD cards is NewEgg.com.
Class 10 is the fastest and the most beneficial to devices like phones or high-speed digital SLR cameras. I suggest class 10 SD cards should you want to run programs right off from the card itself.
Hope this helps! Cheers!
I ordered a lexar 16gb class 6 from ebay and get 9.1 write/30.2 read speeds.Sandisk is the best brand but I haven't seen a class 6 by them. I paid 35$ for my Lexar

I just picked up a 16Gb, class 6 Kingston. I'm running my smartphone apps off it and it is WAY faster than the stock 8Gb, class 2 card that came with the phone.
sometimes the brand are affecting very much.. and also maybe you can try to buy in large store, so you can believe the seller, that it is not a fake one..
from the information, class 10 is the best (idk if this is real, since my class 10 card hasn't come), to find out if it was the right card and not a fake one, search in google on how to test a microSD card..

This is probably a massive noob question, when you install a new SD card, do you just copy and paste the content of the old one onto the new one or is there anything special that needs to be done?

Why don't ya choose class 10?
is it unavailable for yours?
The 64 GB Micro sd are coming!
I have a class 2, never tried anything faster so I wouldn't know the difference anyway, but it runs any program just fine.
so, which would be the best, most stable class 10 micro sdhc card? i can't seem to find a definitive answer, as everyone seems to complain about the cards not being a "true class 10", etc. there are only a few reviews on newegg,
http://www.newegg.com/Product/Produ... 600006235 600082443&IsNodeId=1&name=Class 10
and amazon, a bunch of people complain about the speed ratings mot being true.
http://www.amazon.com/s/ref=nb_sb_s...32gb+micro+sd+class+10&ie=UTF8&qid=1318260310
which one do you guys have experience with, and would recommend? the kingstons are just out of the question, as i doubt that they'd be worth twice the coin.
It would be nice if you narrow it down to specific cards.
Although there is to note that most people do not need anything past a class 4 which is more than enough to handle day to day transfer between phone and card.
Sandisk seems to be a darkhorse here since they don't really show you a class number and it ranges from 2 - 6 mbps. The best way is to simply test it out with a SD card testing program.
thanks for the response. specifically, i like the PNY and SanDisk, but like you said, sandisk is secretive about their speeds. i don't want to buy, test the speeds, and return if i'm not happy with it. and is class 10 not required for recording HD video on our phones? thanks again
nah, class 10 is not required to record HD video. besides if i remember correctly, the dz only records up to 720p. you should still be fine unless you're shooting a 20 minute video.
There are some reports from people with various issues with Class 10 cards. Its not widespread by any means (plenty of people here seem fine with their Class 10), but it seems that Class 10 have more issues than lower Classes. So some here will recommend Class 4 or 6 (can't remember which) as the highest you should get.
I'd stay far away from PNY if I were you. I've owned 2 PNY products. Not Micro-SD, but an SD card and a USB thumb drive. On the thumb drive, the USB port and memory chip pulled/broke right out of the plastic casing with regular use (not damaged in any way). The thing just looked and felt flimsy. But I needed one in a hurry for a business trip, and I bought what the store had. I figured, its a USB thumb drive, you can get these things for free. How bad can it be? And I was shocked when the thing actually broke apart after a few weeks.
Similarly, the PNY SD card I have split into 2 pieces (along its seams). In both cases (PNY thumb drive and SD card), the memory chip itself still worked fine, and it was just a matter of using some super glue to hold together the plastic casing that failed. But it just displays shoddy and cheap build quality. I own 3 Sandisk Micro-SD cards, and a couple Sandisk SD cards and thumb drives. Never had an issue with any of them, and build quality is much better than PNY.
There is a long thread in accessories with SD recommendations:
http://forum.xda-developers.com/showthread.php?t=1042324
DUDE! I had the same problem with the PNY thumb-drive! It was the attache series I think. Anyways yea stick to well known brands that are consistently rated high, sandisk, kingston, adata, etc. Honestly though, class 6 would probably be the fastest you'd need unless your gonna be taking extremely high quality pictures at a very fast speed lol aka multi-shot. But then again I'm not sure our phone is even up too that anyways lol.
I have an ADATA 16GB Class 10 from newegg. Has given me zero issues. I would imagine this is probably the same for the 32gb version.
Not sure if the 32GB would hold up. I found out that I'm not that big of a packrat on the size of the SDcard, so I went with a 16gb instead of paying more for space I'd never use, or take years to accumulate.
h2testw 1.4 log after testing it out when I received it:
Warning: Only 15786 of 15787 MByte tested.
Writing speed: 15.1 MByte/s
Reading speed: 18.5 MByte/s
It was definitely a step up from the 4GB class 4 kingston I was previously using, which was getting write speeds of around 5-6mb/sec. After moving onto the Adata, I noticed speedier loading in the photo gallery like night and day. It used to take 2-3 seconds to load the gallery, especially if it was a big picture folder. Now it takes literally milliseconds to load the content. Of course, this may just be anecdotal and placebo effect, but my general experience with android and sdcards for the last 3 years is on the line about it.
actually i retract the kingston comment, i think they had problems with 32gb class 10 cards specifically now that i recall...

The Sandisk that came with my phone has the class 4 symbol printed on the card...
I'm thinking of getting a class 4 myself, don't feel like paying almost +100% for class 10. I'll probably get an A-Data, as it gives a decent price per GB. I'm just torn between 16 and 32 GB
As for Kingston, I think the quality of their products went down a lot in the last two years.

If you look through the thread I linked on my previous response, you will see there are some folks that claim more data corruption issues with 32 Gb cards versus smaller capacities. It seems purely anecdotal. But my point is, don't assume.
My adata 32gb class 4 is going strong since august...

For me I bought this off ebay ( http://www.ebay.com/itm/380405008880?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 ) and it has been working great for me. I loaded it up to about 28Gig and had no trouble. Currently I have 10gig free.
I've got the Sandisk 32gb class 10.
But the one from Samsung seems great.
The SanDisk 64GB MicroSDXC is also fully compatible despite the device being a sdhc device. Apparently the protocol differences lie on code and not on hardware.

Yea according to this article and many other phones on Gingerbread. I suppose there shouldn't be any problem under ICS.

well. that is fantastic.. Maybe when the prices go down in a year i can get that to upgrade my 32gb card.
I'm debating with myself whether or not if i should go with Lexar or PNY 32GB Class 10 SHDC.. how reliable is PNY with SDHC? Same question for Lexar..
PNY Class 10 32GB MicroSDHC for $41 free shipping..
Transcend, PNY, A-Data.. i'm finding decent deals varying from $30-$40. Which is most reliable would you guys say?
I have had a Class 10 32gb PNY for about 6months and have not had any issues. I would buy another one no questions asked. The read/write speeds were all on par with what a class 10 should be. My write test speeds were in the 12 to 14 range and my read speed was in the 20's. I have used any where from Class 2 to 6 on other brands without issues and the Class 10 PNY out performed them on bench tests.
Real world experience with writing large files ect... was faster. It really came down to price when I originally bought the PNY card and for the price and preformance it has been a great buy for me personally.

I have never had any MicroSD card fail on me. I have used PNY, Samsung, Sandisk, and even unbranded OEM cards that come with the phone. Personally never a single issue. I have had a thumb drive fail on me 5 years ago, but can't say it was the memory chip or something on the pcb board.

I have seen some of the Transcend and A-Data cards be a little thicker than the PNY, Samsung or Scandisk cards. They still all managed to fit in the MicroSD slot.

what do you think? stick with the PNY you suggested or do you think any one of these are a good bargain as well given the company.. i'm looking for who's more reliable i guess.. i don't really know. thank you in advance though.
Anyone got any intake on these microsdcards i'm taking a look at? can't make up my mind.. =/
I have seen between your posts some SD and micro SD cards. I would first pick the form.
Go with the microSD for cell phone and some tablets. Other tablets, cameras, video recorders use SD cards.
Pick up the best value and brand with one pick. The PNY did that for me and continues to be great. I have been taking it in and out of my phones so often the white letters are rubbing off. Still works prefer.

Hey everyone,
I'm thinking of getting a 32 microsd. Card for my S3. I was wondering if a class 10 is necessary or would a class 4 or 6 be sufficient?
Thanks.
Class 6 is sufficent I read somewhere that class 10 is good for taking pictures or something but for this phone class 6 is enough.
It depends on what you'll be doing. Personally, I'd go for a UHS-1 class card. They're just above class 10. Sandisk has a 32GB one for about $40 on Newegg.com. That's what I'm using right now. It has been awesome thus far.
uhs are useless for this phone, no phone on the market supports this feature.
just get the best you can afford, anything above class 4 is enough, but prices aren't much different, so a class 6 or 10 can be in reach.

That might be the case on the international version, but when I'm taking pictures my UHS card it certainly seems to record them faster on my US - AT&T version. I wonder if anyone has done any any read/ write benchmarks to see for sure.
But I do agree, unless you have a need for speed, anything over class 4 should be good for everyday use.

i standby what i said, no phone supports uhs, unless you can prove otherwise.
What about if you use it as USB mass storage? Or making backups
of it? Or it's still limited even though that?
i personally have about 10 class 10 16gbs, and around 12 class 10 32gb, and 4 class 6 64gbs. granted i use only 3 or 4 of them i just have a alot extra. i sued to work at best buy mobile and came up on a lot. couple months ago best buy sold a class 6 64gb online for $45. keep an eye out and look for deals. i do see a big difference in the class of cards. i usually have music and various roms and what not.
What about playing roms saved on sd cards would you notice a difference between class 6 and 10

it's not the card, it's the phone thats preventing the card to reach the limit.
a class 4-10 will work on the s3, you won't notice much of a differences.
---------- Post added at 02:14 PM ---------- Previous post was at 02:06 PM ----------
if you want the fastest card on the market, but not for the S3, you only choice is the sandisk microsdhc extreme pro with upto 95mb/s transfer speed and only available so far 8GB and 16Gb.
or you can consider the adata microsdhc premier pro read 45mb/s and write 40mb/s available in 8gb, 16gb and 32gb.
as with both cards you need a uhs reader to reach the stated speed, otherwise you will only get max read 25mb/s and write 23mb/s which is the standard speed set for sdhc.
Class 6 is the sweet spot
Class 4 should be sufficient enough for normal phone use tho?
unless you are using DSLR perhaps?

class 4 has faster ram, class 10 has faster sequential write speeds
class 4 is better for every day, random use
class 10 is better for downloads and recording/playback of large files and HD movies

you can't go wrong with any of them, both offers stability, reliability and speed.
whichever is the cheapest my lad, both pretty solid brands.
I use Samsung, happy with it. Not sure if this will help but.
Get whatever is cheaper. Both appear to be good cards based on the reviews. Keep in mind that most if not all phones will not be able to take advantage of the Ultra-High Speed (UHS) capabilities of the latest UHS-1 cards (50+MB/s read) as seen in jasvncnt1 SD Card Tester results. I get similar results with my Class 10 cards.
A while back, a lot of people were recommending the Sandisk 32GB Class 4 microSDHC cards over just about anyone elses regardless of class rating. While this may have been true back then, most manufacturers are now producing pretty decent memory. I've got a Sandisk 32GB Class 4 in my Fascinate, a PNY 32GB Class 10 in my Lenovo K1, and a G.SKILL 32GB Class 10 in my Galaxy S3 and have had no issues with any of these cards.
Come to think of it, the only card that I've had issues with is the Samsung 16GB Class 2 card that came with my Fascinate. After about about a year and a half, it became permanently write protected. I can still read from the card, but can no longer write to it.
Hope this helps.
Samsung.
I got that Samsung and its perfect. But would have gotten either one at the time...found the samsung locally at frys first and it was cheaper so it won...no issues what so ever
