What size microSD cards ?

Hi all.
Just want to see what everyone is using as in size and revision.
Why i ask is HTC said ( to me anyway ) that it only takes up to 2GB microSD. On the other hand iv read on other pages they can take the microSDHC cards as well and larger than 2GB so some feedback will be cool before i go spend cash.
Thanks ahead

What is microSDHC?
How is it different from normal microSD

I've just bought a 4gb microsdhc card for my s730 and it's perfectly working.
(microsdhc is the new version of the microsdhc card which allow capacity over 2gb)

My 2 GB card (Sandisk Ultra II) is that fast...
write 760.68 kB/s
read 1976.20 kB/s
Hows your SDHC? (Use SKTools for benchmark)

yeap
yeap the microSDHC is a newer version of the microSD card. bigger capacity, also refered to as Rev 2 microSD.
Cool, looks like ill go for a 4GB microSDHC card
thanks...

I have a 6Gb one in mine works fine was £36.99 from PLAY.com, free delivery + Quidco points

I'm using the 8 GB från SanDisk, and it works just fine.

I have a 6gb sdhc works without a problem.
The phone should take up to 8gb and maybe 10 before it will need a firmware update to read it.
HTC probably has only tested a 2gb.

4GB SanDisk from play.com, £17.99
Pack included a microSD>full size SD adaptor* AND USB adapter for PC!
* not micro>mini>SD as with some cards

well i had 2gb .......then i replace with a 4gb but didnt read the size of the 4gb and it went in as 2 storage card .....so what i did is put the 4gb in hard reset as new and the card read as a 4gb.....so much better....... I instaill everything to my card

SanDisk 8Gb class 4
Working perfect since almost a year.

I'm using a SanDisk 8gb microSDHC for about 3 months now and no issues!

sdhc 8Gb clas 6 wmtorent need storage )

Difference between Sandisk Ultra microsd card and normal card?

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?

http://en.wikipedia.org/wiki/SD_Memory_Card#SDHC_cards_with_greater_than_32.C2.A0GB_capacity
as I understand it the only advantage of SDHC is an increased card storage. And im not sure if an SDHC card works in the HD2.

Both of them should be SDHC (>2GB). I'm asking about the Ultra thing.

Sorry, got it wrong

They're the same thing. One has an adapter however

Ultra means it has higher transfer speeds.
There's also Ultra and Extreme in the regular SDs.
Ultra=15 mb/s
Extreme=30 mb/s
So it's all about speed.

@apallohadas: they have different model number, one is SDSDQY-016G-E11M and one is SDSDQ-016G-FFP. And I suspect that just a card reader will make that difference in price.
@joooe: but they're both class 2?

I've tried several different class cards in my HD2, and regardless of advertised 'class' r/w speeds only changed noticeably if I took it out of my phone and used a card reader or adapter like shown in the "ultra" listing you have.

Hello apallohadas
can you confirm or any one without any doubt that there is no difference in R/W speed between class 2 or class 4 or class 6 inside HD2 with Windows 6.5 or Android
thanks

I don't have Winmo installed on my phone anymore, so I can't rerun that test and I didn't keep the numbers last time that I did it.
But if you'd like to try testing cards yourself, I used a program called H2test and a card adapter. My Class 2 Sandisk 32GB card gave numbers comparable to a class 6 Transcend 16GB.
Inside of the HD2 however, while on Android the tests take too long (setting read/write file sizes of 1GB+.) I've read in several places that the hardware limits performance as though they were all class 2 cards.

There are reviews where a class 4 card is superior to a class 6 card.
Sandisk cards are just great.
In the sandisk website there is no info about the class of both cards. Don't believe they have the same class.

thank you apallohadas for replay
I think so, hardware limitation to Class 2 with HD2 although I read in several places that there is more performance with Class 6 or 10 card in Android especially SD Android
I have Sandisk 16G class 2 and want to upgrade to 32G and I don't want to wast my money in useless class 6 or 10 with my EU HD2,
any one use Sandisk class2 then upgrade to class4 or 6 with EU HD2 and get faster performance in read and write inside HD2 not as disk drive ??
thanks

Which type of memory chip?

Hello. I bought this phone last week and I absolutely love it. I've been searching the forums and can't wait to upgrade Android and install apps. This is my first android phone and I like how it can be customized. Before I do anything, I want to purchase a memory chip for the phone. I want to install and run apps from the chip but unsure of which to get. What size, brand, and class do you recommend? I have a 8gb class 2 from my old phone. Is that good enough? I'm thinking about getting either a 16-32 gb. Thanks.

I have a 8GB Sandisk Class2 for ~12€ from eBay. Works perfectly, even with Apps2SD.

I think a memory card class 4 or higher is reasonable!

I'm using a 16 GB Class 6 (14 GB free memory and 700 MB for Link2SD).
I bought a Class 6 because i heard that there might be some problems with Link2SD/App2SD and Classes less than 6...
I haven't any problems with it -> Ebay 40 €

If you are going to install a custom ROM then I would be careful about using a 32Gb card as I have heard of people having problems with them. As vqt907 has said, I would go for at least a class 4 card.

I have a Kingston 8GB Class 2.
Works very fast, also with app2sd.

16 gig speed 6, with two adapters USB and normal memory card size for 25 pounds from Amazon....works well....d

Ps get sd speed increase from market it's a must.....d
MY ANDROIDSKY

I was considering upgrading my SD card from a class 4 to a class 10, for the speed improvement. So, I first tested my card to see what it's current speed was.
My card is an LD ( class4 8GB, bought off the street in China:
Write: 11.7 MB/s
Read: 18.0 MB/s
If my understanding of speed class correctly, this is class10 speed, not class4.
So I tested my Chinese "Kingston" - mostly likely a "ghost shift" chip, also class4 8GB:
Write 7.1 MB/s
Read 14.7 MB/s
This is class6 speed, not class4.
So, if you buy counterfeit chips in China (or online from China), you can get a class10 chip for very cheap, I paid $13 for my 8GB card. Just test the speed before you buy.
So check the speed of your card before you buy a new one.

... and check out if there is the right memory on the chip

16 gb - class 6
best money-performance ratio .
You will not need anything more .

A proper branded Memory card like Sand disk, Transcend, Kingston and so on.
Never get fakes or non-branded ones as a 99% chance of pre broken risk is at your slide (personal experience)
A class 4 or higher would be reasonable.

I've been planning on buying a new sd card since the default 2gb is waaaay to small and I've got a few questions.
My current write/read speeds are 7.0Mb/s~ and 12.6Mb/s - which class is that?
How big is the actual practical difference between let's say, a class 6 and a class 10 card?

look like class 6, class number is write speed in MB/s. btw, there is no reason to buy class 10 duo very slow pc>phone>pc transfer rate. I can get more then 2-3MB/s (cable, wireless)

[Q] About SD Card

Hello
I got my Legend about 2 months ago, and I have a big problem with storage space...
What is the biggest sized SD card the Legend can use?
What is the type of SD card (micro, mini, etc...)
What is SD card class?
Thank you very much

microSD compliant with SD2.0 Standard (aka microSDHC)
The biggest size available currently is 32GB.
I don't know if even more is possible with microSDHC or if bigger cards will only be possible with SD3.0 (aka SDXC) but that question is not relevant as you can't buy any greater then 32GB yet.
The Class of the SDCard is a measurement for guaranteed minimum speed in random read/write.
The Class does not provide any information about real-world speed or max speed.
For your mobile phone the class is a pretty useless criterion as you don't need any guaranteed minimum speeds but good overall speeds ESPECIALLY sequential.
The guaranteed minimum speed is important for HD Video Cameras for example where you write data all the time at a given speed (resolution).

thanks.
but I DO need class with high speed because I want to use Data2Ext...

Don't pick uSD card based on class !! class tels you MB/s for sequential write only... you need a card that is overall fast, I had 16GB class 10 Kingston and data2ext was just horrible!
Now I'm with class 4 Sandisk mobile ultra and it is in fact faster in every test I ran...
So read reviews before you buy

ye but that is exactly why im asking...

well then, I recommend sandisk mobile ultra as I have it and it is OK, there are probably faster cards...just see the small files read / write speeds in reviews those are of greatest importance

i purchased a kingston 8GB class 4 which crapped out. android kept reported sdcard unexpectedly removed. tried all sorts (formatting in windows, android, quick, long, etc).
RMA replacement did exactly the same, so i'm guessing kingston class 4's are best avoided.

If I recall correctly I have a 16GB microSDHC Class 4 card. After applying data2ext with this card, my Quadrant scores hit around 1500, which is crazy.
This is where I found my card: http://www.amazon.co.uk/SanDisk-16G...P06K/ref=sr_1_1?ie=UTF8&qid=1298984123&sr=8-1
I personally recommend this card.

witch is better class 4 or class 6?

class 6 is better , but class 10 is even better

I've got a Sandisk Ultra Mobile 16gb SDHC which works fine in the Legend. Make sure you format it with the phone to stop it being dismounted, well known issue and the fix

Recommend a SD card size

What size sd card should I get? Would 2gb be fine?

If you're gonna be installing a lot of software you should probably go with 4+. I believe 2 is sufficient if you have it on hand

Thanks

Yes I just got a sandisk 16GB Extreme Class 10 45MBPS for 17.00 prime free shipping

Also RPi has a micro SD card adapter, so I am using my old micro SD card from old phone. They are available at adafruit.com or ModMyPi.com. they are cheaper at adafruit.com
Sent from my GT-I9300

The minimum size SD card I would recommend is 8 GB, also check out this list of SD cards that are known to work well with the RPi and this list of SD cards to avoid and that are known to cause problems and not work.

I think 16Gb 10class SD card is best of speed*size/price.

I looking on sandisk extreme 8GB. But I've read that rpi with some kernels have boot problems with some really fast cards.

I you are pretending to really use the rPi as a "real computer" everyday, install softwares, development kits, etc I would recommend a 8GB or more SD card, they are not expensive(as a guy said, a 32GB card will cost less than 30 bucks in USA. This is difficult here in Brazil, today I bought a 8GB MicroSD card for 30 dollars). If you want to use the rPi for small things, Chrome OS or something like that I think that a 4GB card will be fine.

I Picked myself up a couple of these at the start of this year, Class 10's and on the known Good List and only 20GBP at the moment, which is a bargain. Now all I need a RaspPi to go with it

You can be happy getting the 512MB version then, so waiting isn't that bad.
OT: 4GB ist enough for almost everything, but then its recommended to mount /home onto an external drive for storing user data.
