[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.

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

Which card to buy.

Confused ......omg ebay scares me....duo pro,sdhc or class2,3,4.....can someone help me make a choice.....also is 32 gb properly supported by our device?

Hey,
i've bought a 16GB class 6 card from memorystar...
If you want to install Link2SD/App2SD a class 6 card will be better (Class 6 is faster...)

I saw a class 10 card smwhere......now is this class 10 faster than class 6?
Sent from my GT540 using XDA App

yes, a class 10 card is faster than a class 6 card, but a class 10 card is very expensive.
Don't buy a noname class 10 card for 30 Euro that might be a fake...

yeah i have that doubt too , about if a 32gb sdcard is properly supported by our phone and not brick it in the trying lol , also how will i know what class if my sdcard? is there a software for check that info?

On the most cards its on the body...
If not you can also ask the shop where you bought the card

A memory card with class 4 or higher is good!

Buy class 6, thats save

Try to avoid buying memory cards on ebay unless you have a clear idea about memory cards and the ebay seller. Some cheap chinese cards on ebay could be fakes which either would not work well or would have the capacity inflated by a driver hack.
microSDs come in class 2, 4, 6, 8 and 10. The speed difference between each of these classes is tremendous. However, the price is also different. Class 10 being most expensive and class 2 being cheapest.
You'd have to strike a good balance between speed, price and capacity. I'd recommend a Class 6 with 16GB capacity.
Of course, if you have lots of money to spare, go for a class 10 32GB.

it is faster but you will only see difference when you move big files from pc to phone.

what not to buy : Kingston 8gb class 4

Best uSD card to run CM7

I just put one of the CM nightly builds (build38) on a uSD card (sandisk 16gb class 2) and there is a major lag to even enjoy the device. I have been reading about that sometimes class numbers on the cards don't mean too much.
Which card would you recommend to run CM from (Brand/class/where to buy) from your experience?

any class 6 card should be plenty enough (as long as it has enough room for the ROM and stuff) even class 4 should work much better (but still some lag i beleive, idk ive never tried it)
newegg is a pretty good place to shop for them. Heres one such card - newegg.com/Product/Product.aspx?Item=N82E16820211341&cm_re=8gb_micro_sd_card-_-20-211-341-_-Product

There is a long thread about this on here and the class 6 Transcend 8GB card got the most mentions for good perfomance. The probability for issues to arise increases when using cards over 8GB.
I have a class 2 Sandisk 8GB and class 6 Transcend 8GB card. They both work well.

I have been buying the Wintec cards from newegg for a couple months and run them in both my captivate and my nook they work awesome. Class 10 and fast. http://www.newegg.com/Product/Product.aspx?Item=N82E16820161411

Patriot Signature 8 GB Class 10 MicroSDHC
Did anybody have any experience with this card?

Are you running a rom (e.g CM7) off the card? Did you ever run a speed test?

Not at this time. What speed test would you like if I loaded one up on the card and booted from it?

I used that card for HC v4 and it was fine.

I've got 4 uSD card: one Dane-Elec 2G no class, one Kingston 2G no-class, one Transend 4GB class 6 and one PNY 8GB class 4. All run CM7 very well, maybe I didn't pay attention but didn't notice much different in performance. In benchmark, the write speed is about 5-7 MB/s.
The higher capactity 16GB card seems to have more problems, other than that every card will do.

You should check into the random read/write performance of small files on these cards. sometimes the class 6 or 10 aren't all they are cracked up to be. Fast transfers of large file yes, but general performance can suck.
sandisk class 2 or 4 cards can have excellent perf. I have a class 10 that is outperformed by class 2/4 and 6 cards.
if you are having problems with crashing, etc. try a basic sandisk and see if perf. is better.
there is a thread about it but i can never find it.

[Q] What class sdcard to buy?

Hi guys,
I'm getting a new sdcard for my phone, but I'm not exactly sure what class should I get. Is class 4 enough or should I get at least class 6?
I'm worried about full HD videos recording.
Any tips appreciated

Im going to get 16gb class 6
Sent from my LG-P990 using XDA App

Equipped with Team MicroSDHC 16GB Class 6.

I've got a 16GB class 4 and am happy with it.
In my opinion, the prices of cards class 6+ are too high for the extra transfer speed they offer.

tnx for the tips

16gig class 6 = 20$ off ebay.
And yes its a real class 6 as I have tested its speed

I use the microSD 8 GB I had in my Nokia 5800 and I do not know the class membership, but I like it here because we have spent nothing

I have 64GB class 6 i believe.

I'm using Lexar 16gb class 6, worth the price, the performance is near a class 10 microsd.

Nevr forget the thanX button

In my sensation, on a class 4 8GB card, i got 13 MBps full Hd recording and on same card but LG 2X, i get 18~19 Mbps fullHd video
I don't think class matters that much....
By the way i use internal SD storage for camera and later transfer to extrnal SD

I've read that class 10 is actually slower at reading small files than class 4
You can see a lot of data (real world data) here: https://docs.google.com/spreadsheet/ccc?key=0AjPE3ZAD2eVudE9vZmQ3aHlfTkFvU2J4ZUplRDJQTEE#gid=0
taken from this thread
So if you're going boot from SD for example I would get a class 4
If you are planning on transferring a lot of movies/music/photo's or recording video's in high resolution onto the SD, I would recommend a class 10
But best of all: do some research and pick a card that excels in both, e.g.
SanDisk Mobile Ultra 32GB Micro SDHC Flash Card Model SDSDQY-032G-A11A
Samsung Class 10 MB-MSBGA/EU

I have one Samsung 32gb class 10 (MB-MSBGA) and i'm quite satisfied with it.
It costed 32€ (1€/Gb is really a nice price ) and it's fast
Antutu Bench 2.7 gives me writes of 17-18MB/s and reads of around 20-22 MB/s (these scores with only 4gb free in the sd card (full of music and hd vids))

I use Kingston 8G class 4.
In regular use it has enough speed.

I have a ridata 32GB class10.
Really happy with it too.
My rule is to get class 6 and up. But that's me because I tend to play around with my phone and may come a time where I need to boot from it. As of now, the class 10 helps with loading apps (I hope). Since I have CM7 and it's using the external card as the default sd mount.

team 16gb class 10 forever

i think class 6 is good and the performance is good too. I never heard any of my friends got problem with it

I'm using VERICO 16GB class 10, very good performance!

I had to decide between Class 6 and Class 10 for my P990, but since the Class 10 just had a small additional charge I picked this one.
Samsung Class 10 for 18-19€ (Germany)

Which SD to buy ?

I have been using Sandisk 16GB Class 4 for a while now, and I need to increase my storage (32GB)
I am confused between these two cards:
Samsung 32GB Class 10 for 1599 INR (29.43 USD)
Sandisk 32GB Class 4 for 1216 INR (22.38 USD)
Which one should I go for ?

If your not looking for fast write speeds or using as a "swapped" internal memory, just go for the class 4, never pay more than you need for memory cards, they date to fast.

I thought greater speed (class10) would be nice,
I was just wondering if samsung is good against sandisk or not ?
Also does samsung cards work with WP7 ?

i am using samsung class 6
16gb
and it works flawlessly for wp7 and native sd (android)

Why not go for the 64GB cards that are available now? They are selling for around $50 (for a SanDisk class 10 even) and they work great in an HD2. See my posts about this here http://forum.xda-developers.com/showpost.php?p=33028241&postcount=9 Basically the same post here as well, but I added a bit more info http://forum.xda-developers.com/showthread.php?p=33102891#post33102891 You can never have too much storage space.

Be careful with class 10 cards as for phone memory use they are not the best.
Good quality class 4 or 6 is best all round card with better sequential speeds that are more in line with phone usage thus better performers & cheaper/easier sourced plus less prone to issues/compatibility ...

i use sandisk

I bought the Samsung 32GB Class 10. It is really fast. I'm using Android via NAND and you can improve your smartphon experience by upgrading your system with this card a lot.

I use a 16GB class 10 Sandisk micro sd

I use SanDisk Ultra microSDHC UHS-1 8GB card.
Worked very well with JellyTime NativeSD ROM and now with WP7 ROM 8858. So cheap and lightning fast. I recommend it for everyone, great memory card!

I use 32 GB Class10 Transcend Extrem Speed (Ultimate), this card has a very well performance with WP7 and NativeSD.

Second place in random speed (4k R/W)!
Which is important for WP7, NativeSD or Nandroid with A2SD, DataOnExt, ect.
