Class 10 Micro SD Cards

How come only class 10 Micro SD Card I can find are Kingston brand? on Newegg.com review said it has horrible write speed although it is a class 10.. Can anyone point me to the right direction on best class 10 micro SD money can buy? (16gb at least)

I don't mean to be a jerk, but, do you really need a card to move data that fast? I mean I'm all for speed but really, don't sweat the class ratings so much.

Yea, I spent $100 on that Kingston class 10 16gb micro sd and I was severely disappointed. I think the problem is that the phone doesnt need to read and write data that fast. It makes caches of all the pictures, album info and art, and anything else if needs.
I spend $53 on the San disk 32gb class 2 micro sd and cant tell the difference. So now I'm using the 16gb as a flash drive for my key chain.

Where did you find a 32GB card for $53??

I think he might have gotten it when Verizon screwed up there website and had it for sale for about an hour for $50.00. That is how I got mine for $50.00

Verizon's online store the 1st day they listed it. They were supposed to have sold the card for $150 to anyone, $99 to people buying a droid x. Well, they dun goofed up and someone listed it for $49. I think its still listed for $99.

Anybody tried this 32 gb sd card? Awefully cheap, is it worth it?

Found this on Ebay, don't know though. It comes out of Shanghai and the price is cheap. I'm more worried about cheap crap wrecking my phone. Anybody try one of these yet?

it won't wreck your phone, but it will probably die after a few weeks - if that long. If you but it, be prepared to throw away your money at some point and all the data on the card.
SanDisk probably won't warranty it because it is probably counterfeit.

don't think u ever will get it
last 16gb card i bought over ebay was about 7€cheaper then all the rest and i never saw it - got money back by paypal thats why i tried (and he had about 100 positive votings).
this seems to be about 50€ cheaper then a normal 32GB card and he has 0 votings - so he propably tires to get the money and vanish into dust before Paypal can claim the money from him.
would buy something more recent.

I bought a 16gb kingston class 4 on amazon, it was around 45$, and they had a promo that if you signed up for an amazon credit card you get 30$ off your first bill. so bought it and paid it off for 15$.
Honestly, with Froyo coming soon and apps2sd, Id really reccomend investing in a good class 4 or 6. The faster the speed of the card, the faster your phone will be able to pull and push data to it.
Another note, my class 4 can move large files at about 8-9 mb/s, but if there are many small files it will only run about 3 mb/s, so Id really recommend a reputable brand. That is not to say the kingston doesnt work good, just to say one of those cheapo 30$ cards advertising class 6 will probably run much slower and break apart quickly

Good point about the speed issue. Can't wait for Froyo.

Class ratings apply to write speeds not read speeds. Theoretically you can write faster to higher class cards, but this usually applies to direct writes on the device (camcorder recording to card) not USB between phone and PC. The USB copies (PC to phone) may be faster, but you have a additional overhead of the USB bus.
Buy a name brand card. I have an 8Gb Sandisk class 2 and it works great for Camera, camcorder, and anything else i want to do with the phone software. My 1080P camcorder has class 6 cards, but it requires it.

I'd steer clear from buying memory cards/ usb flash drives on eBay. I've seen way too many people get scammed on getting what they thought was a 16gb flash drive and end up with a 128mb stick with 16gb screenprinted on it. These microSD's are no different.

Actually I tested this using the sdhc adapter directly to the SD card slot. so no USB/phone interface interfering here. And again, thats what I was stressing. Buy a name brand card, probably a class 4 or 6 considering the move to froyo.

So you got the same MB/s throughput with the card reader as well as the phone connected to the PC? Still puts the USB bus in the way. EDIT - NM I see what you were measuring.
I wonder what the transfer rate is on the phone - back and forth between internal SD and external SD.

Huh, interesting concept. I dont even know of a way to test that

I bought a 32gig card from China for 18 bucks shipped. 1st time I've been scammed on ebay. It seemed to show up as a 32gig, but the phone wouldn't recognize it and wanted to format it....sure thing I figured. Now it shows as an 8mb card that won't format no matter what I do. I disputed it to paypal after the auction/seller disappeared on ebay, but they want me to send it back to China to refund. I considered this might happen and was willing to risk 20 bucks, but it didn't end up well. The funniest part was that it showed up in Kingston packaging, but the date was 2008. I'm pretty sure 32 gig microSD's didn't even exist in 2008.

Thats terrible!! well good luck getting your money back... Lol so I guess if it looks too good to be true, it probably is. Id just stick with trustworthy sellers, brands, and sites, and look for good deals!

Hi Everyone,
Please do not risk your money on the any of the EBAY 32GB cards.

User manual says 16gb is the limit
"Important!: The Camera, Audio Postcard, Music Player, and Video

Did anyone get a 32gb to fly?

I am not sure where you found this - but the official specs call for up to 32GB card:
http://www.samsung.com/us/mobile/cell-phones/SGH-I897ZKAATT-features
Many people are using 32GB cards. It is the limit of the SDHC spec, so the 16gb is probably a typo from somewhere.

Whoa. My quote was from page 34 of the user manual. It's crazy to find that download on the Samsung site. Here is the link (I can't post links yet in this forum):
downloadcenter.samsung.com/content/UM/201008/20100806021015421/SGH-i897ATT-Captivate_English_User_Manual.pdf

Not sure if the one I purchased is the same because the item post has been removed but mine came from Beijing I believe. Came in a Kingston package which was obviously fake. Put it in my phone did a format and it showed a 32gb card. Writing files takes forever directly from the computer but everything looks good so far. Mainly using it for music.

[Q] Best sd card

I have a scan disk 8gig sd card, the one that came with the phone. I'm looking to upgrade the sd card. I have two questions (I did search on xda sorry if I didn't see this question answered already)
1) What's the highest gig the Evo 4G will support?
2) What type of sd card should I get, like company name and all that?
Thanks.

32gb, san disk class 6

There really isnt a best card, just get the highest class you can afford.
The one piece of advice though, do NOT buy memory cards off ebay. 80% of the cards on there are fakes. Purchase from an authorized retailer, like newegg.

The company that has had the most positive results is SanDisk. Not all packages will say what class the card is so look for a "C" with a number inside of it. 10 is the best right now but SanDisk ones are hard to find. Like a previous poster said, Class 6 is the most popular and fairly nicely priced.

Unfortunately, it's not just eBay. Both CircuitCity (when they were in business) and most recently BestBuy have actually had fake SanDisk cards ON THEIR SHELVES. That's pretty brazen by the forgers.

Because SanDisk seems to be such a big target for forgeries, I switched to Kingston for my memory cards in my phone, tablet, camera, my kids' Nintendo DS, etc. I've been very happy with them.
Just recently I got a 32gb Class 4 Patriot for under $40 (for my Acer A500 tablet) and I'm very happy with its performance. So don't overlook Class 4 if money is a bit tight because it will get you a much bigger card for the money that still does the job well.
I have a 16GB Class 4 Kingston in my HTC Evo 4G and currently have it partitioned for running Synergy RLS1, which is also performing very well.

what do you think - surely better than than class 6, or not?
be aware some people are not fond of play.com and their customer service. i have never tried their preordering service - perhaps others can share their experience?

whew! I just bought 64Gb Class 6 version. Since this is a new product, I hope it'll also work with our Note.

It works. But didn't want to work initially, formatted to fat32 and still nothing, but all of a sudden it works. Plugged in and out of my phone finally worked. When transfering, my phone crashes (turns off) Running latest Stunner, have to pull the battery, dunno what the bug is, but I have to install files plugged in directly for faster transfer, kinda slow with USB Mounted anyways.

I trust Rakuten, they are the best source to get East Asian goods and are very reputable, I guess you could say their the equivalent to an Amazon specialising in East Asian goods mainly from Japan.

thanks -
they are a reputable company and been around for ages but apparently their customer service is not very good
do you know if this card would be better than the class 6 64gb sandisk ?
are there any class 10 cards where the read data access times are as good as class 6?

Oh great if it's work with our Galaxy Note !!!
It's strange because it's a class 10 and it's not cheaper ... the class 6 cost very more ... I don't understand this one.

This is my biggest worries about buying microSD card with price that is "too good to be true".
I have bought many many microSD and SD cards (since the days of Windows Mobile phones) and there are tons of fake cards. I noticed that this is usually when the prices of the card is really cheap.
To the OP or whoever bought this card, what's the R/W speed? Use SD Tools from Google Play (link) to measure the speed. In the past, I have bought brand name card from even reputable seller (Amazon Prime) but Amazon themselves got FAKE card. I.e. I got a Kingston Class 6 16GB and the R/W speed is less than 1 Mbps (!!!) My Sandisk 8GB Class 4 R/W is more than 2Mbps.
Not to say bad thing about OP, but just to consider the above.

Hey thanks!
it is always a good idea to be cautious when you buy a memory card and that is why it is important to buy from a reputable store
it seems you were unfortunte to get a dud card as amazon (not amazon market) are usually a safe bet but i guess nothing is for certain in this world ... except death and taxes
Play (again not Play 'Market') are reputable also and been around for many years and i would trust them not to sell fake cards but it is their customer service that is bad. They usually discount things on a pre-release but sometimes they get the availability date wrong and so you might be left waiting. I know Amazon don't withdraw money until the item gets shipped but i don't think that is the case with play and that is where you might end up having a bad experience if they delay shipping etc
some still say a class 6 is better than 10?!!?

I need a good 16gb micro sd?

I'm looking for a good quality or at least good performing 16sd card. I'm trying to find a good value, and I've found some class 10's on ebay for like $13, but I know there are variables such as what format they are, but I'm not too hip on what's best? I have a class 4 SanDisk 8gb, and it's time for something faster with more space for all of my backups. If someone maybe has an ebay or amazon link to something they've bought & have been pleased with that would be great! Thanks in advance.

You can grab a 32 gb from Wal-Mart for a little under $30. Why not go that route? I have 2 of them but use a 64 gb atm.

Class 6 and reliable when I got mine.

I just ordered a UHS-1 30mb/s read speed, sandisk 32Gb micro sd card for 28 euro, for performance i would go with a class 10 or UHS-1 which operates as class 10s maximum speeds
Ideal for HD recording etc.
On a side note, any memory cards purchased off ebay should be tested for their true capacity, use a german software called H2testw, its gold standard for testing memory read/write speeds. And total capacity
One can not determine if the seller is 100% genuine or not unless its a credible company
It is possible to have a memory card stating its 32GB size for example, but in reality this card could really be only 8GB in size, a tiny program could be installed on a hidden partition and as you save more files to your card, once the 8GB limit has reached it overwrites your oldest files with the newly saved files to keep space, operating systems are fooled into thinking the particular card has a full capacity of 32GB which is not actually true

Grabbed my PNY 32 gig at best buy its a class 10 and has pretty good benches online for $40 right now. It isn't as good as a deal as ebay or amazon but with all the insane amount of counterfeit cards I really felt the still over priced on sale micro sd was a better option.

The worlds fastest micro sdhc is the sandisk extreme pro at 95mb/s, the largest size is 16GB at present, but the speed is useless in a phone, as no phone supports UHS 1 specification.
if it's to be used in a phone then the samsung 16GB class 10 is the fastest at write 21mb/s and read 24mb/s, largest size is 16GB.

Thanks Man! I never heard of sdhc before? Until Android supports it then it won't do much good for me, because I only use sd cards these days for transferring files from between phones, media storage, etc. I generally use usb drives for all my other portable storage needs, but I'll definitely be keeping my eye on sdhc for any advancements in compatibility.

My new sandisk class 10, is well over twice as fast as those old class 4 cards I was constantly shuffling around! This is great for transferring large rom files & movies to external memory.

Better go for SanDisk sdhc class6:thumbup::thumbup:

I meant sdhc sandisk extreme pro, and in the midst of screaming children I didn't finish what I was typing. Though I did not know that 64gb or larger is called sdxc? Is that why it seems they have to be formated differently out of the box or ppl tend to have issues when using them with Android?
