Micro SDHC Card Speed

I heard there was a 32GB Card included with the thunderbolt. The 6GB card on my Droid X was only class 4, so I replaced it with a class 10. Anybody heard anything about the speed on the card included with the Thunderbolt?

A card of that capacity will more than likely be a Class 2. I can't see them putting anything more than that in the phone considering the price and that 32GB microSD card's are far from openly available as it is.

It's actually class 4. :]

From what ive seen and heard is that its not neccesarily the class that determins the speed as it is the manufacturer. Sandisk from my understanding has the fastest cards out and that is in part why you pay a premium price for them. My buddy bought a 16gb class 10 , I honestly do not remember the manufacturer, and his old 8gb class 4 sandisk is way faster according to him. He was pretty pissed after finding that out.

I have a 32 gb Sandisk (class 2) in my Inc and I store all of my music and video on it.
I even have a couple of full 2 hour videos on it. I experience no lag or any other issues with it.
I have also installed the "Let's Golf 2" app from the leaked TB RUU on it and it runs flawlessly.
The only place where the speed is any issue for me is putting large files on the card, it is slow. But once the files are there the read speed is fine.

As far as Sandisk over the last 5 years I have had 3 cards corrupt themselves and die. Usually it is within 6 months.
Since I switched to Kingston branded cards. From what I understand they are also sandisk but the batches that didn't meet standards for Sandisk themselves.
Anyway I've had this 16GB Kingston for well over a year and works faster than the Sandisk.
If any card would fail it would be running XDAndroid off the sd card like I am now.

how do you test theres cards without paying?

i couldnt download it

Whatever class it comes with will be fine for me. I just can't wait for the xtra 16gb of storage. I know for most people that 16 is plenty, but with all the roms on my 16gb card, and switching it between my fascinate and incredible plus my 5gb of music that 16gb disappears quickly. I do like having the 8gb internal of the droid x but undone ever see myself using it all until androids apps get more polished, and with polish they will grow in size very fast. I can't wait til we has a preloaded maps that can work without cell signal!!! Go tbolt!

[Q] Microsd card 16 or 32GB ?

What sdcard can you recommend 16 or 32 GB? Of course I am considering only 16GB class 10 and 32 GB class 4.
I would like to know some points of view, like if it is useful to have 32GB rather than 16, how works the phone, I mean slower or normally with 32 and so on.
Thanks for your help

Well tell me this.. are you even using 16 or even 8gb of data on your micro sd card? 32 and 16 seem overkill.

Actually I have almost full my current 8GB, you know some ROMs for emulators ,some movies etc. so maybe 16 shall be ok.

My advice is that if you can afford to pay for a good 32gb from genuine traders, then go for a 32gb. It will save you the trouble of buying a 32gb sooner than later.
I have a 32gb on both my winmo and on my DZ. Can record without crossing everything for fear of running out of space.

Be very careful if you buy from eBay. I bought a fake, but since I had paid using paypal, I got my money back.

if you're going 32gb, then I'll be assuming you'll be putting your music library in there.
I"m also in the market for a 32gb micro sd (maybe if i can get my paws on a class 10, but that's really dropping some serious money on it [atleast for me]) since my music library is at a scant 16gigs (maybe more, but i havne't checked) so I wouldn't mind 32gb so i have lots of leeway to get my stuff in there.

There is only one question here:
Music or no music?
If you have music on your phone, go for the 32GB.
If not, I'd go for the faster 16GB.

I just bought a 32GB Class 10 Patriot card for a little over $100 at Frys .
Definitely an improvement over the 16GB Class 2 I was using . Buy the best
once and never look back IMO

id say grab a kingston 8gb class 10, just got mine for 19.99 ill wait on a 32 class 10 when they're not so obscenly priced..

I have one of these too, make SURE you follow the format instructions on patriots forums otherwise the card is going to go tits up and corrupt all your data once it stores over 16GB of data. There are "issues" with newer android/wm7 phones and patriot class 10 32gb microsd cards (they admit its true). Their current workaround/fix is to format it a specific way WITHOUT LBA and with 32k clusters.
I haven't tried it yet since, I said screw it, and went back to my 16GB a-data class 6. I lost all my data on the patriot 3 times and using my phone for music is not that important.
Other people on that forum say the "fix" works though so it may benefit you to format it per the instructions if you haven't already and you are worried about data loss.
I put the 32gb patriot card in my dslite so my daughter has more games to play. She's 6 and is beyond happy with all the stuff on it now. Anyways, here are the two important threads over on patriots website for the 32gb class 10 LX card.

I didn't notice enough of a speed difference between the class 10 and class 6 on my g2 anyway. I DO, however, notice a difference in speed when I use the class 10 card on my ds lite. Certain games don't stutter or freeze with it.

Ok i have bought 32GB class 4 Kingston for some about 90USD. As i had been reading i have found the highest class 4 for 32 instead class 10 :/ so i was too fast.

[Q] Which MicroSD do you use??

Hi there, I just bought the Sensation and I started the research for a good Micro SD to use on it. On my previous phone (the Desire I have in my sign) I had a Sandisk 8GB Class 6 which never gave me any prob, but I'm reading here and there that with the size of the new ROMs having less than 16Gb would mean meeting a few problems when it comes to have more than a couple of nandroid on your SD, plus video & pics in HD require more & more space.....SO: I wanted to get a 16GB class 6 or 10 but I'm having quite a hard time to find a Sandisk one (I'm wondering if Sandisk even produce something like that...) and at the same time I read here & there in various forum people having some trouble with non-sandisk memory card
At this point I thought to ask all of you which card do you use and if and what problems did you experience with it(?!?)
Tried to use the search tool but couldn't find out much out of this subject...
P.S. If you choose "Other" in the poll please then specify with a post which one you use exactly!

I have the Lexar 32 GB class 10. It works perfectly fine.

Sandisk 32gb, class 4, its perfect

SanD ftw! Haha

PNY 32GB Class 10 working flawlessly.

So it looks like SanDisk wins once again anybody else?

the Kingston 32gb class 4.

Probably not. mmmmmaybe some choppiness on hd video playback, but more than likely the only thing you'll notice is it takes longer to transfer large files too and from the card.

[Q] 32GB SD Cards

Hi all,
I'm thinking about buying myself a bigger SD Card soon.
I'm thinking about going for a 32Gb card, I can't justify splashing out for a 64Gb card IMHO.
I've been looking at a few cards, I've seen and heard that these are pretty good.
http://www.amazon.co.uk/gp/product/B005FQLN28/ref=noref?ie=UTF8&s=computers&psc=1
I've been looknig at the first 4 from this search: http://www.play.com/Search.html?searchtype=allproducts&searchsource=0&searchstring=32gb+micro+sd
The card I posted a link to first is in that list, I'm wondering about the classes though. Which class would be best? I've heard that either 6 or 10 are the best for phones.
Does anyone have any Exp. with one of these cards?
Cheers,
T-L-H

I have a SanDisk 32GB Class 4. Works fine, I got it on sale for about £16.50 which was a bargain.
IMO Class 4 or Class 6 is best for phones, unless you transfer films and things often
If you're going to buy a Class 10 I'd go far a SanDisk Ultra due to the better small file write speeds.

I use 32GB Sandisc card class 4, for me it's OK

I use a Lexar Class 10 32GB. Works like a charm! £29.99 from Amazon UK! http://www.amazon.co.uk/Lexar-32GB-...2ZTM/ref=sr_1_1?ie=UTF8&qid=1329762527&sr=8-1

I have a question and need assistance from experienced members here, I have a HTC Sensation and i am also looking forward to increase my SD Card memory to max 32 GB Class 10, now i have doubts over this, kindly open HTC official site and check Sensation technical specs, it says that Expansion slot: microSD™ memory card (SD 2.0 compatible) and while i was checking the product on an online site, it says Fully compatible with SD 3.0 Standards, the product is Transcend Micro SDHC 32 GB Class 10. so my question is that since HTC says sensation is SD 2.0 compatible, will it runs SD 3.0 Standard card without any problems ?
kindly answer as i need to take decision asap.
thanks

the best purchase atm is: Samsung micro SDcard class 10 - good price, good quality, very fast

Go for a class 10. I really notice a difference using my SLR camera when I swap between a Class 6 and the 10 - the 10 being way faster.

Class 10 all the way. I have a class 10 and it's slow, I wonder how slow will a lower class be.

I use class 10 cards in my DSLR, and would normally recommend them, however after installing CM7 on a microSD for my mother's nook color everything I read said your better getting a SanDisk class 2 than anything else, even in class 10. Apparently there is not a good standard for rating cards. I would recommend looking up specific benchmarks and choose from them.

I would not suggest a class 2 card as Android has issues reading it due to it being too slow. I have used class 4 and class 10 and I can feel a huge difference in the read and write speed.

Careful when buying sandisk especially online. There are some bad apolss out there selling improperly marked sd cards which say class 10 but really are just class 2.

Well Class 2 guarantess you 2MB/s, Class 6 6MB/s and Class 10 10MB/s.
6 is enough, 10 is better, see what you can afford.
Probably a tradeoff between speed and space.
Check how much space you really need.

Is it class so important?
I mean..when you have a class 4 isn't just enough for a smartphone?

Same thought. I have an 8GB class 4 SD card and i feel fine with it.

For just having media files on there, probably.
If you start putting apps to be run from there, you wan't as much speed as possible.

I think it much more depends on your ROM, not your external card. I have installed my apps on the ext2 partition and it does not appear to have any differences.

I havent noticed any differences between class 6 and class 10.

From personal experience, the speed of the card makes a big difference for the Desire because of all the app2sd games.
As someone mentioned before, brand and the store are also very important.
I bought a Lexar class 6 16GB and quite happy with it.
Make sure to do proper alignment on it.

I was thinking of this link coming into this thread, it needs to be a forum-wide sticky. For a camera, a class 10 would most definitely be required. But for Android, there does not seem to be a consensus.
Good luck

you should buy a class 10 dude samsung or another

Go for a class 10. If you aim for sales and such, you can get one for the normal price of class 6 cards.
