class 6 cards?

are there any class 6 16 or 32 gb cards?
my class 6 8gb card just died and im looking to get more space to get rid of my ipod but i dont think a class 2 card would be fast enough to handle 12gb worth of music fluidly like a ipod....
i tried looking for some san disk class 6 cards but i can only find class 2 16 and 32gb cards
and some random "ts" cards that say their class 6 which i really doubt they are

http://www.amazon.com/Transcend-mic...1?ie=UTF8&s=electronics&qid=1277324728&sr=8-1

lmao i feel stupid now thanks a lot bro i think i might buy that card then

so i found a class 10!! 16gb card on amazon by kingston what do you guys think? 30 more bucks than the class 6... worth it?

They get kinda warm, or even kinda hot, and can burn out. Especially in the Evo, underneath the battery, which already can easily get >100 deg. F, and not being able to vent.. yeah. Also if it's a cheap card it can just be made really crappy and r/w operations can damage the memory

How do you verify the card is real? I bought a 16gb class 2 from eBay. It says scandisk on it and it only cost 26 bucks. I haven't seemed to have problems with it, but worried about the overheating.

Use h2testw to check for capacity. You can't really tell if it is sandisk or not. Check the read/write speed using atto disk benchmark.
Anyways, a class 2 16 gb microsd goes for ~30-33 on Amazon via third party seller/fufilled by Amazon (less likely to be fake)

if you have a sandisk chip that you know is genuine, compare the two chips. Other wise Google image for a sandisk chip and compare. I think that sandisk usually has a serial or part number on the chip. Not sure of the details but I've heard that fakes are usually lacking something. Also compare the size and build quality to the chip that came with the phone. Sometimes fakes are slightly larger or have crappy glue jobs. Google how to detect a fake. There's some good info. Most of it is what I said.

Ok conducted a test and got this.
Warning: Only 15101 of 15193 MByte tested.

You can now delete the test files *.h2w or verify them again.

Thanks for all your help guys!!! Looks like I have a good card.

i just got the 16gb class 10 card and here are the benches. im also testing the stock card the phone came with. enjoy!
btw i tried fixing the pics but i dont know why they are coming out like that i give up...

so i synced all my music and pics and the card works great just as fast as the itouch... but now it brings me to another issue.... the itouch is louder the evo is loud enough but it just kills me to know that i could go louder on my itouch this is bull****

which is card to get ?
you know... i personally would go with some 8 gig class six models, example, transcend is selling the 16gig class 6 for 64.99 on new egg but also selling the 8 gig class 6 for 19.99.... which means you could get 24 gigs for less with over 5 dollars to spare which you could use to get a nice 5.99 2.0 card reader all free shipping. besides most custom roms and all future android updates use apps to sd which shortens the life of you sd, why put all your eggs in one basket? i had 2x 8 gig cards on my g1 using apps to sd for a year and a half and never opened the second 8 gig card sold it in its package when i sold my g1 had 1 gig ext3 partition 256 mb swap, plus over 2 gig of music and a bunch of t.v shows its hard to fill up an 8gig card on a mobile device.

I wish I knew about the class 10. I just got an AData 16gb class 6 for $59.99 to replace my other one that went bad.

32 gb sandisk

hi, i hope this is right place to put this and also to let you know i did do a search of the forum and couldn't find an answer...
i just bought a 32 gb sandisk micro sd card and inserted it into my galaxy s, i have tried to add thing to this via my pc and also via astro on my phone, each time it seems to get a little of the way and then the external sd card unmounts its self (at least i think thats whats happning ) and then i get an error on my pc saying the read/right disc was unreadeable, then my pc says that the external memory needs formatting before i can continue use, if i then go back into my phone i notice te external memory is no longer mounted, this is driving me mad, if anyone can help please do before i throw my phone out the window lol....i am using a rooted galaxy s with 8gb onboard memory

It sounds like you have a bad card. I would return it for a new one.

Let me guess, eGay. . . . .
I have 2 fakes sitting right here. . . . This is a huge scam.
Buy memory from reliable sources only.
my 16Gb card is a 1Gb in reality.

Hmmm...did you make sure that the USB mode is set to debug and then the dial up mode is off. This same thing happened to me last night. Make sure that's done. Restart the phone and THEN plug the cable in. I'm guessing it keeps flipping out and there's a red pyramid in the upper left hand corner?

Bad Memory
I believe you got a "fake" memory. I have experience of this before. A lot of programmer will be able to re-program the card from 2G to 32G or whatever the capacity they want. just google it, there is a free program will be able test it and tell you the real capacity your card has it. if the price is incrediblely low, there will be a problem. if you got it from ebay, just dispute it and get your money back.

Look for the program h2testw, it will tell you actual capacity of your card, likely 64-512mb only.

Yes, scams. You should only buy to respective shops. Sadly some of my friends bought things like 10pcs. Too bad they got scammed. I learned my lesson and it is just somehow like 3-5$ difference.

I'd say stick to Newegg and Amazon for memory purchases.

Which is the best company for 32 gig class 10's

I've bought 8GB and 16GB cards from those Chinese deal sites. They worked out alright. They weren't too experience. But I agree, if you want a 32 GB card, go buy a reliable brand from a credit-worthy source.

where can u buy cheap memory cards

I've got the Patriot LX Series 32gb Class 10 Micro sd card in my Galaxy S, and it's awesome... was $99 with free shipping from newegg.com
http://www.newegg.com/Product/Produ...=patriot_32gb_class_10-_-20-220-547-_-Product
I've had great luck with mine, and it flies.. now it's $83.99 after mail in rebate with free shipping..

Newegg had the 8 gb transcend for 15... that thing is so fast 15 MB/s read and write. Was using a sandisk was awful.

I ordered a 32GB Class10 Lexar SD from Amazon compliments of swagbucks. Waiting for it to ship. Anyone used Lexar cards before?

I'd say Sandisk is the best quality memory card you can buy. Class 2 and 4 Sandisk work great for WP7 or for running Android off of on a HD2. Class 2 and 4 cards generally have a better random access speed than class 6 or 10 cards. You only want higher class cards for digital cameras where you are writing a lot of file sequentially. For running operating systems where itneedsto read small amounts of data from many parts of the card quickly, a quality class 2 or 4 card works best.

You should test the card with CrystalDiskMark and HD Tach to get the random read and write speeds and random access time. I'm curious as to how the class 10 Lexar rates in those speeds.

patriot class 10 32GB microsdhc announced

Patriot has released a Class 10 32GB micro SDHC card.
Newegg is out of stock but has the price as $99.99.
Just thought y'all might want to know.
Edit: Newegg sez its availability will be 1/8/2011

Do our phones support 32GB microSDs? I read somewhere that 32GB didn't work with our Vibrants which was really ****ty but...was what it was.
Can someone either confirm this or deny it? Specifically, do so by testing with a specific 32GB card...

I've had a 32 GB microSD in mine for months - works fine!
I listen to music (I have approx 20 gigs of music stored on it) and store the pix I take with the camera on it - haven't had any problems.

The benefit would probably be in it being able to keep up with HD video recording, and decreased time scanning the microsdhc card when booting up, or mounting or unmounting it.

Yet, the bigger the card and more data would slow down the scanning. Double edge sword.

Maybe. I depends on how many files it has to catalog. I imagine that a 32GB microsd with 10 2.3GB movies would scan much faster than a 8GB card filled with mp3s

Have you noticed that the card makers are going away from what the Class system is supposed to be. Look at the transfer rates of the Class 4 cards now and they are equal or better than some of the class 10 cards. Doesn't make sense to me, but maybe people didn't understand the Class system and its relationship to transfer rates.

So the Class system is supposed to specify a minimum transfer rate, which increases as the Class goes up.
However, it seems that it is applied arbitrarily by different manufacturers.
Check SD card wiki for more information.

Newegg says they are available
Newegg just notified me that the Patriot 32Gb class 10 micro SDHC is now available. Now it is $99.99.

Newegg also has a Wintec Class 10 32GB for 82.49 - it isn't by Patriot, but it comes with a lifetime warranty.

I have a Wintec 16 gig class 10 in my Vibrant.
Works very well, very snappy performance.
I've never figured out a way to test it in the phone, but thru a adapter on my laptop it hovers around 17-18 meg thruput both read and write.
(edit) BTW, I got it at Frys.
It was 38.99$
Nice price.

Patriot LX 32GB Class 10 benchmarked with SD Tools v1.3
(HTC Desire HD + Android v2.2 rooted)
Oh, by the way, about the SD Class system, it only rate the minimum sustained write speed of the card, but not for random writes.

Wow. That's pretty awful if the benchmark is to be believed.

i have a scandisk class 4 32gb , it has a write speed of 4.8 and a read 11.4

Semi-related, I have a patriot 8gb class 10 card that is holding up very well, including quick transfers. Patriot seems to be pretty good stuff, so I'm considering getting a 16 and passing the 8 down to my girlfriend. I don't think I could find a need for 48GB on the phone, except to hold backups for reflashing.

Wintec 32Gb micro SD class 10 anyone tried?

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.

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.

It's not all about the class rating.
Nothing can beat the Sandisk cards on random read and write speeds.

I just bought 2 for 18.48 each..thanks for the tip!
As fast as this phone is, it doesnt matter what class card you use; also, just tweak the read ahead speed with rom toolbox or one of the other programs that tweaks that, and you will never know the difference between a class 4 and anything else...

Seems like a good deal. Might have to jump on a 32gb card in the next couple weeks. Don't think I will ever use that much space but I guess I could use it to put some movies and tv shows on my phone.
