SD card question

hey guys, which sd would be the best for the legend? iam interested in an 8gb one, but i dont know which company to choose. Also dont know about the "class"system. Can i use a class 4 sd on this phone? thanks and regards

Class 6
Sent from my Legend using XDA App

Mine is class 2, 16 GB by SanDisk and it works great. Even apps2sd+ works with it...

oh, vert great 16 GB by SanDisk and it works great.

i'm using Kingston 16GB Class 10, doesn't feel that much fast and i test with SD speed test it only run up to 4-5MB on Legend, so i guess, Legend hardware doesn't support new type of SD

I'm now using Pretec 16GB class 6 and it is just fine with Legend, but before I used 8GB Sandisk ultraspeed and it was way slower in Legend...it went around 20 / 15MBps (R/W) in the card reader, but only-MBps in Legend...so Legend definitely reads/writes much slower...

Any a2sd mod can work with any sdcard, but you might get some lockups on slower ones. I was using original 2 GB sdcard (I think it was Kingston class 2) till yesterday and had no problems using a2sd whatsoever...

[Q] X8 support class 10 of memory?

I bought 8G (Class 10) memory card. but i don't think my phone(x8) support it?
in all of tests, My phone shows has class 4. Is it correct?

did you buy the card from Ebay or is it from a reputable source? Eg are you sure the card is a genuine class 10?

I don't know, how can i understand it is original?

insert your card into cardreader and record big file, and check record speed.

Have a look at the sdcard.
The most of the sdcards have a little number in a circle on it, and that´s the class of the sdcard.
So, if you can find a "10" in a circle on your card, it´s class ten.
if you have another number in a circle on it, then it´s not class 10

It may be a hardware problem, but testing the speed on a pc would be taking you out from the doubt.
I'm using a class 10 8gb Kingston microSD. No problem at all.
However, I experienced heavy writing problems with class 4 8gb Kingston. This was the reason why I had to resell this card, only to check with my own eyes the problem was on the x8 and not in the class 4 microSD.

I tested my 8G-Class 10 microSD with Ram Reader,
File: 699 Mb
write: 90 s ----- 7.8 Mb/s
Read: 65 s ----- 10.75 Mb/s
File: 398 Mb
write: 50 s ---- 8 Mb/s
Read: 20 s ---- 19.9 Mb/s
How do you think a bout my class of microSD?

Its class 8

kingstone products have a lot of compatibility problems, i know they're popular but they suck.
I'm using an SDHC A-Data 8 Gb class 10 and works great.

Those results mean nothing, there are lots of things that can influenciate speed. Also, the cards' speed is tested on factory with a special machine, not a computer, so real world speeds are always a bit slower. If the card was a fake i think it would be getting far worst performance.
Test it on a desktop pc (rear ports) using a decent card reader.

I have a kingmax class 10 8GB.
In pc, i can reach around 14.x mb/s.
In phone, fastest is 8mb/s, but in average 6mb/s+.

Friends
At last, I tested my microSD (class 10) in Galaxy S I9003 with "SD Tools v2.1" & "SD Card speed test v1.9" applications, They show that the class of my microSD is 10, then tested again in x8 and show class4 or class6.
conclusion: Our x8 can't support class 10. it support class up to 6.

It's true that the sd card interface of the X8 can have a limit below class 10, but remember that there are always factors that can limit the speed.. Partition type, allocation unit size, ROM, kernel.. But yeah, i won't be surprised if it had a limit of roughly 6MB/s..and it's not that bad

Class 10 is very smooth for ungaze...

I test my 16GB V-Gen class 10 memory card with sd tools and the result:
read speed : 14,4 mbps
write speed : 8,2 mbps
i use 32k allocation unit size when formatting through computer,,

i have 8GB AData class 10 and work fast and smooth
Read 20 mb/s
Write 12 mb/s and some time more

can someone confirm if X8/W8 can benefit class 10? cause I have here class 6 offered by a friend for a very cheap price cause it is second hand

[Q] Issue with 16GB MSD card

Anyone has the problem with scandisk class 4 16gb msd card in your 2X?
mine is rooted with CM7.1 and before and after i upgrade to 7.1
constantly having problem with the sd card
either is not present when physically in the slot or it cannot be read.
does 2X has any problem of using 16gb msd card?
i usually have to eject and insert back the sd card in order to solve the problem.

I have the same problem (i'm running Miui)
Sometimes the 16 gb sd gets very hot and my phone can only see externalsd/download (not my music and other data)

welcome to the club...

maybe it is the "class"
try class more lower
like "class 2"
...
if I'm wrong tell me.

I use a 32gb class 4 card, currently in Topogigi's v2.0.
My 2x doesnt read the whole card automatically at startup. I can access the media files through music and gallery app, but not via file manager. After reinserting the card though, it does read everything and theres no problem

so we have problem with 16gb class 4 sd card..
havent been able to find a class 2 16gb card to test it out..
so glad that im not alone with the 16gb class 4 issue in our O2X..

CM 7.1 with a Samsung 16GB class 10, working good.

The same card, phone (v2.2.2) and problem
Two days ago I updated it to GB, so we'll see now

i have transcend 16gb class 6, with GR5 and HP RC9 it's fine here. have you guys already trade up for your sd card?

I have transcend class 10 16GB on CM7.1 no problem yet.

I had problem with class 4 card. I think 6 is a minimum, no problem since.

Hello, I use verbatim 16gb ( class 10 ) is very good but price is not good

memory related problems

hi friends plz help me out of this problem...
1- running out of internal memory as only using 4GB card
2- which will be suitable micro sd card for my phone as i am going for 32 GB but i am not able to understand CLASS FACTOR OF CARDS i just want mu phone to run smooth either through applications or high res. videos. i am going for KINGSTON but if u have other suggestion plz let me know
plz help me

1) For more internal memory, use Amarullz Script.
2) Buy a class 6 card. It is enough for the Ace. You can also use Class 10 if you watch HD video(not on the Ace of course! ) and you will use the card in another device also.
Kingston is not bad but my personal preference is Sandisk.

I have a Sandisk 32 GB Class 10 and it's not working fine (even if the phone recognizes it, it doesn't recognize the apps intalled on it).
I've been told that 32 GB it's too much for the ACE, so if you got one and it works fine I'd like to know!

i'm got a 16gb class 6 Sandisk running Amarullz Script with a 2gb ext4 partition which is more than enough to get over 100 apps with ease and runs quick btw look about forums for app 2 sd scripts theres many with many different names
and ace can run a 32gb sd card

[Q] What SD card you use? ZR destroys cards

Hey everyone. I started my ZR with an older (don't remember the brand) 8G class 6 memory card. All was fine for 2 weeks.
Then I bought a Kingstone 16G class 10. After 2 days, error message "SD Card unexpectedly removed". The card was dead, no computer could read it anymore.
I went back to the store and changed my card. Another Kingstone 16G class 10. After exactly 2 days, the same error. Card is completely dead. I cannot go back to the store, because they checked the second one and it was working fine.
I am sure the phone somehow destroys the cards. But the first one I used seems to be fine.
My question is: What memory cards do you use? Should I try a card with a different brand, a different capacity or a different class?
Thanks!

I'm now also using SanDisk 32GB UHS-I. Speed is very good and stable. I have 2 dead Kingston SD already so I would avoid them.

I did have a SD has been removed failure once but that i think i restarted and it was ok.

Using a SanDisk Mobile Ultra MicroSD Card 64GB Class 10 UHS 1 (not plugging SanDisk or anything. I just copy pasted from the email confirmation after I ordered it). Been over a month and no issues so far.
I think Kingston has issues. Bought a 16 gb one from them and it packed up in a week. My dealer replaced it and cautioned me never to buy them as though cheap, they're prone to failure. I then bought a SanDisk and have been using them ever since

I use a Samsung 32GB Class 10.
It's great, fast and didn't cost that much at the time. I think it cost me € 31,- at the time.
That was 1,5 years back or so and now there are really cheap.:highfive:
Big capacity and high speed, so you can watch series/movies on your ZR!

I use a Transcend 32GB class 4 and it's working fine without any problems.

What sdcard are you using now?
Previously I said my Sandisk 32GB class 10 card is fine. But after upgrading to 4.2.2, I was having similar issue as yours. First there was "SD Card removed unexpectedly" message appear. Today my card is not recognized by the phone anymore. Though it's still working fine in PC and other phone.
Similar issues have been reported by users of other Xperia phones as well. Some Xperia L users said the problem is fixed after upgrading their firmware which was released a few days ago.

im using samsung 32gb class 10 with no issues so far.
http://www.samsung.com/in/consumer/memory-storage/memory-cards/micro-sdhc-plus/MB-MPBGC/CN
and im on 4.2.2

So it looks like it's a problem of class 10? Hmmm. I wish I knew the exact problem before I buy another one.

Using Sandisk 16gb class 10 Ultra HC - 0 problems,fast and stable

Last night I switched to my old Kingston 32GB class 10 because my Sandisk 32GB UHS-I can no longer be recognized by the phone, thought it still works fine in my PC and old phone. So far zero "unexpected removal" has been detected. Interestingly, I bought this Sandisk sdcard a few months back because the Kingston was not working properly in my previous phone (HTC Incredible S).
So this post starts to make sense. Maybe class 10 cards doesn't play well with smartphones after all.

I have a SANDISK Ultra microSDHC Card UHS-I, Class 10, 32GB for Android.
So far I have no problems with it, so I don't know if it's the same SD like you were using @itandy.

I have the same one too man but no problems here I've even been flashing back and forth between firmwares testing out different regions. If you still have the warranty you should try get a replacement.
Sent from my C5503 using xda app-developers app

I doubt it's the problem of my Sandisk card since it's working great in PC and in my old phone. In fact, when I first saw this post my reaction is the same. It must be your sdcard. But now I'm not so sure. I'm very surprised when I Googled about the issue and found many people are having similar issue with different Xperia phones. Specifically the latest Xperia L firmware fixed issue with class 10 sdcard too.
