I decided to order from Amazon the card. Is it better to Kingston microSDHC 32Gb Class 10 or Samsung 32GB Class 10 Micro SDHC Extreme Speed Card? nowhere to be found a benchmark, I saw a mention on the forums, such as that Kingston is quickly. any ideas?
what? no one? no one has good card?
I don't really think it matters, not to me anyway.
That said, have a look at this thread: http://forum.xda-developers.com/showthread.php?t=1150369
i saw it, it wasn't helpfull...
I would suggest going with the kingston one myself, never had any problems with them in any of the phones I owned.
Might want to browse newegg for sdcards and look at the feedback people leave for sdcards there, a lot of people post their benchmarks on their phones there.

I hope I posted this in the right section, I wasn't sure where a question about MicroSDHC cards would go here.
By the way, I live in the US.
I have been Googling this for days now, and coulden't find any conclusive information, especially since most of it was from random tech blogs and not respected tech/research sites.
I am looking to buy two MicroSDHC cards to use in a Photofast CR-5400 ( http://www.amazon.com/PhotoFast-CR-5400-MicroSD-Adapter-Dual/dp/B001I0T92Q ), speed and performance are pretty important as I will he handling a lot of data through it.
First of all before I start, anybody familiar with this adapter? Where would be the best place to purchase one so I don't wind up with a Hong-Kong bootleg? Ive had trouble purchasing flash memory online before from places like Amazon or Ebay where the memory was a bootleg that didn't perform anything like the real thing.
Now, I know that Memory Stick Pro DUO devices are generally faster than SD or SDHC devices, but AFAIK that device sets them up in a RAID 0 configuration so I am hoping that will help, this is why im trying to get the best performance MicroSDHC cards I can afford. And trying to get reliable information on these things has been a lesson in confusion.
First of all, it almost seems like the class speeds don't matter. Ive seen benchmarks that showed class 4 or class 2 cards outperform a class 6. Whats the point of these classes if they are so meaningless? How can a class 2 device have faster write speeds than a class 6? And is this classification only for writing or reading too? Why are the "ultra" models of some cards, which are supposed to be very high speed, listed as class 4?
Second, I heard that there are other variables that usually are not listed anywhere, such as Random Access Times, which from what I read are internal processes taking place in the card itself rather than having anything to do with the card reading/writing to whatever it is plugged into. And I really have no idea what else could be a factor.
I was looking at THIS Transcend card ( http://www.newegg.com/Product/Product.aspx?Item=N82E16820208475 ) mainly because the previous 8GB version ( http://www.newegg.com/Product/Product.aspx?Item=N82E16820208453 ) seems to be the best one you can possibly get, the 8GB model is class 6, rated as very high speed, and even has a low Random Access Time. But that doesn't mean that just because the previous model was good, the next one will be of the same quality, and on top of that I don't know if it'll even matter in that Photofast adapter or not. Not to mention its kinda pricey, don't forget that I will need to buy two as well as the adapter (though since the 16GB Memory Sticks came out at over $200 and they are barely around $100 now, and the 32GB still isn't out yet, I am going to assume it will still be at least $50 cheaper than just buying a 32GB Memory Stick............ when they come out).
So what would you recommend I do? Where can I find information that makes sense of this? Where can I find good benchmarks/testing done on these cards that on top of speed measures the other factors as well? Where would be the best place in the US, retail or online, to purchase such a 16GB MicroSDHC card for the best price?
Thank you for your time.
what are you using the Memory card for? (what application, video/photo taking, loading applications...)
Class X just says the minimum write speeds on an empty(defragmented) card... 2 means 2MB/s write, 4 means 4MB/s etc...
some SDHC cards also come with another rating... 133x that says max 20MB/s speed, depending on the manufacturer, that may be write or read speed
best place to buy is directly from Newegg/Tigerdirect, or from Amazon fulfilled by Amazon itself or a reputable merchant

Patriot 8gb class 4- very slow from pc to card ???
Anyone having any current luck with Patriot 8GB Class 4 micro sd's?
I copied everything from my PNY 2GB to my netbook. Very quick as expected...
Formatted the Patriot FAT32. Tried to copy back to the 8GB from the netbook and it was painfully slow. So slow it is not usable.
Both pc and Tilt recognizes the Patriot as 8gb.
Anyone having similar problems or any suggestions?
Possible formatting issue... No more Patriot SDHC.
I think I got it...
Took about 12-15 minutes to copy back to card.
It appears to be a formatting problem with the XP fomatting.
Used this... http://www.sdcard.org/consumers/formatter/
Tried the Wife's new HP laptop (school issued) last night and had the same problem. That pointed me to a possible card issue.
Moral of the story- google is your friend.
Just to be safe, I would stay away from Patriot's 8GB C4 cards.
I would just try another brand of microsd card. Sandisk are reputable but usually the most expensive, though on amazon 8gb cards can be had for less than 20 bucks. Kingston is another good brand.
I'm going to buy a 16GB microsd card from sandisk. I've been finding on Amazon and found these two products:
Sandisk 16GB Mobile Ultra MicroSD Card : £36.00
SanDisk 16GB microSDHC Memory Card : £15.99
I've also noticed they're all class 2 (can't find a class 4 or class 6 sandisk). So what is the difference between them? I'm using the card for Windows Phone 7, so which one should I buy?
Ha, i'm looking to buy a 16Gb card for my htc desire and I was looking at exactly the same cards.
As far as I found so far the ultra version seems to be class 4.
If you have any new info it will me much appreciated.
well in some pages you can find comparative boxes about those micro sd, i remember that microsd 16 gb sandisk (class4) is more faster than 16 gb kingtons class4 , so i supousse that this ultra micro sd is like class 6 real XD, i will find some information about it, oh plz don't forget that some devices don't support those kind of micro sd (an example htc hd2 has little bugs with microsd class 4, i have one...)
Sorry if i don't write well but i'm peruavian =)
Hey guys,
Can any of you confirm if Android is booting from Sandisk 16GB Mobile Ultra MicroSD Card ?
I want to buy one but i saw in forums that some cards doesn't work for this..
the ultra one has the better speed and more stable than the normal one. And, it has the same compatitablity.
So, if you are not concern about the price, the ultra one is the better choice.
Also, that should have the extreme III type, that is the best~
Go for the Ultra microSD, it's faster!! been using a 8Gig on my phone and damn its fast!!
16GB Sandisk Micro SDHC
I'm currently using 16GB Sandisk Micro SDHC (class 4) for my LG P500. It is fast & I have not encountered any issues so far.
I've been using Sandisk memory cards for other gadgets & I think it is one of the most reliable brands that is available in my location.
With sandisk/kingston, class 2 should be fine too. CLASS 4 might help recording high def video
Stick with the name brands and forget the Chinese non name brand off off of Flea-bay, they are crap and do not work imho!!
The more expensive cards are usually just higher speed.
I use fast cards in my DSLR to help when shooting bursts. Slower cards fill up, and drop the fps.
I'm currently using 16GB Sandisk Micro SDHC
Go for the Ultra microSD, it's faster!!
You should choose your memory card depending on what you're going to use it for. Either way, you should go with Sandisk cards, as they are the highest quality and produce their own chips. Kingstons should be avoided even though for some reason they are known as a quality brand... kingston just buys chips from other manufacturers and puts their name on them.... you will find many different kinds of chips inside kingston, so you will find more variation and defects from batch to batch.
As far as class, that is only referring to the sequential write speed. If you are getting the card for a digital camera, then a high class card is good, because you will be writing a lot of files sequentially.
But if you plan on using the card for WP7 or to run android of off, generally a class 2 or 4 card is better, because they have better random access speeds. The tweaks card makers do to make cards have higher sequential write speeds many times will lower the random access speed, so you will have more issues running WP7 or Android off of a class 6 or 10 card.
for 8gb ultra i got with usb2.0 card reader : 13mb/s write , 20.5mb/s read
I know the thread is old, but still.

I know thread is too old to write anything. But still (since google pointed me here)...
I've used both types of cards and have found that Sandisc ultra (Red & Black) is far better in speeds and reliability than the Sandisc simple/normal black colour chips. Also know that there are further/more better than ultra, called by Sandisc as extreme and Extreme Pro.
Also warranty for all is same: Lifetime. And Sandisc provided me a new chip within 25 days after my old 32 normal chip went faulty.
Re
I would always buy a class 10 card, because when you copy your photos it doesn't take so much time...
I discovered - the hard way - that "normal" class 2 or 4 MicroSD cards won't stay alive very long on Samsung Note 4 or similar phones... One day they stop working and all pictures and info is lost forever. The only MicroSD that can get the job done is a Class 10 UHC Sandisk card. I have used Kingston and all died only after a few months, specially if you install apps on them. They can´t handle the workload and you will end up losing everything you have on them. I have one of the red and gray Sandisk cards and it's awesome. It's fast and it's still working after 2 and a half years of use in a Sony Xperia Z2. Gotta love this little tough card.
Browsing newegg i found this card, Never heard of this brand. Anyone have any experience before? Class 10 for a 32gb micro sd seems like a real good deal to me.
http://www.newegg.com/Product/Produ...11&cm_re=micro_sd_32gb-_-20-161-411-_-Product
That's incredibly fast indeed. The class thingy is official, because it's just as an official label as an Full HD TV is Full HD. So you can't doubt about that.
How many formats it will survive is the question, but I think the quality of SD cards doesn't matter so much anymore (except the classes)
I am wondering about that as well. It says it has a lifetime warranty so that's great. Also I found this at Fry's (32GB MICRO SDHC CLASS 10, PATRIOT PSF32GMCSDHC10) for $109.99
I just bought two WINTEC 32GB Micro SDHC Class 10 cards at Fry's Electronics today, and so far they're working very well in both my Viewsonic G-Tablet and Samsung Galaxy Tab.
I haven't had time to benchmark the card(s) yet, but there's quite a noticeable difference in the performance of my Samsung Galaxy Tab.
So Far - So Good...
Well, based on just the reviews I've read on Newegg recently for Wintec-branded cards, I'd have to avoid them myself.
I was looking at the 16GB version of the card you're looking at now (Item=N82E16820161405), from Wintec and a Class 10. The feedback appears mostly negative, with many complaints about the card not functioning at all when the customer received it, several about it's speeds diminishing over time (under 6 months), several more about data corruption and/or complete failure occuring within a few months, and one unsettling one about Wintec blaming the customer for damage/abuse and refusing to honor their "Lifetime Warranty."
I can't speak from personal experience, and customer reviews are not 100% reliable, but there are enough people on Newegg dissatisfied with their Wintec MicroSD card to convince me to purchase another brand.
I have two of the 16GB Class 10 cards and they both are working pretty well. One is in my Nookcolor and the other in my Nexus One. Benchmarks were 18.7Mb/sec sequential read and 16.7Mb/sec sequential write. It's a good price and works well so if you are on a budget or just don't want to spend too much money for a card I would recommend these. Hope that helps.
Saw this on newegg for a pretty good price, a class 10 32GB card for $76 sounded good to me. While there are a few bad reviews I don't hold much stock in newegg buyers tbh. They aren't always the most technically proficient individuals and I always like to try things myself anyway. I'll be more than happy to fight to return the thing if it turns out to be bad. Hard to pass up this kind of thing .
Here's the newegg link in case anyone is interested. Mine will get here Tuesday so I will post back with a benchmark. Fingers crossed.
EDIT: After some google searching about similar cards from this company I found a thread on this forum about the 16GB model: http://forum.xda-developers.com/showthread.php?t=830491
If you skip to the last page you can see the OP and others had some problems with it. I figure I will stress the crap out of it when I get it, try and find any problems before the clock runs out on returns. I'll probably just write to the the entire card, read it all back, then erase and repeat until something bad happens. Im sure doing it this way I can recreate a month or two of use in just a day or so.
I just ordered on of these yesterday from newegg, I'll be sure to report back how well it works in my SGS once I receive it!

What file system did you use for those devices? I'm not sure what I should format my 32gb card as for my Droid 2. So far from what I have read from google searches it seems android doesnt support exFAT or NTFS which means no large file support :/. I could format it to ext3 or something but that would mean I couldnt use it on windows. Not sure what to do.
EDIT: Well I've been reading and writing to the whole card all day and so far no problems. Writes at 15MB/s and reads back at 20MB/s, pretty good. No corruption or slowdowns at all.

Just wondering, how much did that run in USD?
its already stated in my previous post.
Damn, I guess those reviewers were right. Phone is crashing alot, all apps that use the SD card freeze up the second they start. It was working fine on my PC but my Droid 2 Global doesn't like it. Lame. Thank god for Youtube's return policy.

stick with the usual brand, and you should be ok.
sandisk
adata
kingston
kingsmax
pny

transcend etc.
and stay away from ebay.
I have been running one and while it is not stellar I get decent speeds with it. The write speed is 9.4 MB/s and the read speed is 19.9MB/s according to the sdtools app. It is noticeably faster than the class 2 card I was using. I have it formatted with fat32.
I am wanting to replace my SD card in my phone for a 16GB.. It seems the best cards out there are the Class 6. A LOT of the class 10's I can find get horrible reviews stating the perform really badly. I am looking for some recommendations on what to get.
The card must be a good performer for apps2SD, and be at least 16GB.
Much appreciated for your feedback.
You wont notice the difference between a 6 and a 10 on the phone itself. The only time you will notice the difference is when transferring files to and from the phone and a pc.
Good to know. Any recommendations on a good class 6 card?
I have a 16gb class 6 Kingston micro SD and its great no problems whatsoever
Sent from my nightly EVO
16gb class 6 komputer bay from Amazon. Kombuter bay is a direct seller on Amazon; I couldn't be happier with my card and how fast it shipped. The best part about it is the price(31 bucks shipped).
if i understand it correctly, with a class 10 micro-sd the phone doesn#t work faster ...only copy some file between a pc to micro-sd get faster?
thx
If you look at your card that it originally came with, it should have been a class 2 or 4. Class 10 isn't worth it in an evo.
thank you for your answer.
which kind of micro-sd would you prefer? San-Disk/CN-memory/...?
Hi, i wanted to replace my class 4 sandisk, because i need more storage and want just to buy the best available.
The problem is which of these cards are better, idk since no proper SDTools results available. Can you post some if you have those cards?
For anyone holding sandisks, please make sure your card is bought before 3 months, i heard older and newer sandisk card had difference in performance.
If you want high quality pick Kingston.
They will not let you down in terms of build quality.
Also, class 10? Talk about overkill. This will go as fast as a "bat out of hell with its ass on fire"
Hit thanks if I helped.
