[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 have 32GB Samsung class 10 and I'm very satisfied with it, only 35 Euros

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)

[Q] Which SD Micro memory works best for the Nook Color

I have been searching all over the place for a list of "supported" SD micro flash memory for installing and booting for example CyanogenMods CM7. I have found where people recommend not getting slower than a class 6 but not which brand works best. I am using a Patriot 4GB LX Class 10 and it seems to be doing ok but wanted to know what others were using and what kind of luck they are having.

I'm having good luck with a 4G Sandisk class 4.

Lots of discussion here: http://forum.xda-developers.com/showthread.php?t=1005633

I will add that none of my Patriot SD cards regardless of the class worked consistently or smoothly. After having a ton of weird lock ups and delays (with FC's) I bought a 2GB Sandisk Class 4 and the same exact builds worked fast and like a dream. I then bought a Sandisk 16GB and it too worked perfectly.
Half of my problems were fighting SD card performance issues. There are likely others that are good but it appears the Sandisk Class 4 are a solid starting point.

Agree with Awats
After having problems with Patriot and Kingston I have had rock solid results with SanDisk 2, 4, 8, and 16 GB all class 4. I've tried a couple of off-brand 32 GB class 10 with uniformlly lousy results. Of course YMMV.

I have had zero issue running Phiremod 6.2 off my 16GB Sandisk Class 4 sd (with Dalingren's 4/24 kernel, set at 1200). It has been fast and stable for more than a week. I can't wait for the new kernel that fixed the sleep/battery drain issue.

I bought a Sandisk 16gb Class 2 that works flawlessly with Honeycomb. Only $24.99 at Radioshack right now...if you hurry!

I am using a Transcend 8 gig TS8GUSD C6 with no problems . I think its almost snappier than off of the stock eMMC

How does that Sandisk test out? I have an 8G Sandisk class 2 that tests out as better than class 10 in SD card tools. Not sure if SD card tools is actually testing right. I'd be interested to see how yours tests out.

Just some real world observations that my sandisk cards perform much better than rated, about a class higher I think. I've got an adata and a patriot (class 6 16GB) that haven't given me any issues so far, but I'll never buy another kingston (poor performance, bad cards)

Radio Shack has ALL of the SanDisk cards on sale until 5/14.

I'm running a Transcend Class 6 8GB MicroSD in mine and so far it's been running great. Noticeable difference over the class 4 sandisk I had in there before.

If you're running CM7 off that Transcend, I'd be interested to know if Pulse works without FCs or other issues on yours. I ditched the Transcend Class 6 8G for a Sandisk Class 4 8G.
http://www.appbrain.com/app/pulse-news/com.alphonso.pulse

Which app are you using to test the speed?

Sandisk, 8 GB, class 4 here. The Sandisk class 4 is the way to go, IMHO.

I am using a Transcend Class 6 8GB, running fine. Will buy a Sandisk 16GB to try out.

this.
i've tested many cards with zone bench on the mac. class 4 sandisk outperforms all the others on random read/write of small files. it also coincides with how well my sd card installs run. some cards would run ok but now and again i'd have problems, especially multiple downloads running at the same time from market. I don't have this problem with the class 4 sandisks

for honeycomb: A-Data 4GB class 6 (writes at 6MB/s, reads at about 10MB/s, got it for ~$14, cheapest 4gig class 6 around these parts)
Quite noticeably better than my previous class 2 8gb samsung I got off eBay, which I now use for storage of videos/books & cwm flashing.

16GB CLASS 6 vs. 16GB CLASS 10

I have found 16GB CLASS 6 strontium brand which cost around 26USD. You think 16GB class 10 is a big difference for class 6?16GB Class 10 is still not available now in my area. What do you think? Planning to use it on link2sd/app2sd to focus all my apps on SD

Both are fast but class 10 is faster.

I use a transcend 8Gb class 6 SDcard. ofcourse, apps2sd is already included with most Custom ROMs (you do NOT need to move apps to the SD card, a partition,ext3/4, is used as apps and data storage and is treated as internal). Use Link2SD only on the stock ROM.

What i mean is that class 6 enough for day to day operation oe gaminf ie better buy class10?

Class indicates minimum data rate.
6 = 6MB/s
10= 10MB/s
So it is almost 2x faster
Some of "pro" class 10 have speed over 20MB/s

This isn't a huge difference for using app2sd. You can search in web a test of both sdcards. If the price difference is so big, buy the class 6 one.

Guys will our beloved W8/X8 benefit the class 10 speed or it is only for card reader? I mean in terms of gaming. Does class 10 outshines class 6? cause right now Im using a class 2 stock 4GB microsDHC with the write speed of 4.9 MB/s and a read speed of 11.3 MB/s on SD Card tools

You only need a class 10 card if you will be doing 720p video recordings. Since our cellphone can't record in 720p, it is not worth it. If you plan on upgrading your phone soon, then you'd better wait.

i have AData 8GB class 10 card and i pay for it 15$ dollars and worth that money because is very fast and good..

I have AData 16 Gb Class 10 for 28$ and its great =) fast card for good prize.

Class 10 is faster a lot compare with class 6. Because I am always copy files from Office to my laptop everyday, i feel the difference.faster 1.5-3x.
But, our x8 is only run about class 6 speed. So class 10 used on a x8, the speed is only faster about 5-10%.
If you ask my comment, i will still recommend you to buy the class 10,because: it is faster, and the price is not a big difference. maybe few dollars. you still can use the memory card on future phone.

Hmm I had bought a RiData 16GB Microsdhc class 10 worth around 35USD. But when I test with sd tools in market I can get only 9 and if lucky 10.1 most of the time 8.9

Class 10 cards suck at reading a lot of small files (gaming).

but is that normal for class 10? my stock class 2 can go over 3

that is normal for our x8. my stock class 2 was able to run at around 4mb.
my current kingmax 8gb class 10 able to run at 7-8mb
in pc, that is 14-16mb.

Kingston 8gb class 10

I really want to share with you guys this,before i bouth this card: Kingston SDC10/8GB i had an HP 8gb class 4,but the diference between the two is noticeble.Files are copyed very fast...i'm not saying that the HP was c*ap,it was good but the way i acces now my music,videos and copy new content its really a joy...even the androidOS scanes the card faster at boot.
I may say that the Kingston is twice as fast... and the card itself cost me 49lei with taxes (thats about 14$ US).
Do you guys know a benchmark tool?

BENCKMARKS
Kingston SDC10/8GB: read- 21.78mb/s
******************write- 9.0mb/s
HP SDC4/8GB: read- 12.34mb/s
************write- 5.1mb/s
the results from SD Tools app

use antutu bencmark it can do bencmark forsd card read, write speed

The speed increase has to do with the class of the card. Class 10 is way much faster than class 4.
I'm on my way to buy a class 10 Kingston SD too.

of course. class 10 has minimum speed of 10 Mbps while class 4 only have minimum speed of 4 Mbps...
any class 10 microSD will be faster than that HP, or whichever class 4 microSD.

im using transcend class10 n the best read only 16,7mb/s

how are Samsung's Class6 , 8 gb cards i have ordered one for me
and guys do i need to root my phone to run those benchmark tools

the greatest and fastest micro sd now is UHS (ultra high speed)..
it's above 10 class bro

The best one would be a 32 GB UHS Sandisk for me :good:

Anything above Class 10 is supper fast...
Well, I'd suggest you to take a SD card over 16 GB..because the Ace has less internal storage. Then you can partition and get rid of low internal memory problems.
