Hi,
just got a new 16GB Sandisk Ultra class 10 card for my ageing HD2 and tried firing up a tytung CM12 Nand rom data on ext4.
i installed from magldr with the zip file on sd card and installed ok.
i have used this rom before on an 8gb class 4 but was hoping for a bit of extra speed.
the problem is that each time i reboot, i lose the changes and the phone goes through the initial setup.
what causes that?
while it was running, before the reset and losing everything i added, these were the figures:
Sandisk class 4 8GB HC
read 19Mb/s
write 4.1Mb/s
Sandisk Ultra class 10 16GB HC I
read 14Mb/s
write 8.7Mb/s
so class 10 is down on read speed but double on write speed.
--------------------------------
incidently Sandisk Ultra 64Gb on my HTC M8
read 107Mb/s
write 45Mb/s
times have changed...
tytung has said not to use UHS ultra cards on the HD2, but I have not heard of your problem before. They usually work fine for a bit then things start to go wrong. How did you format it to ext4?
Hi, @robbiep: thanks for the info. i do remember something about a warning now you mention it.
first partition was fat32, about 12GB and second was ext4 about 4 GB.
i had a 64GB Sandisk ultra in there before when i used it daily but just found the order for it and it was sold as class 10 but actually was Sandisk 64GB Ultra XC I (not HC I)
the 16GB was cheap so i will write that off to experience.
read speed was actually slower that the calss 4. i was really looking for a class 6 or 8 as i heard the class 10 were not really suitable for a smartphone but couldnt find any.
8GB is back in there now and all working ok.
still really surprised just how fast the M8 is now

Might sound like a strange question, but what would you suggest getting for most stable Android run. I've had a SAN DISK 16GB but it would always get corrupt and formatting (tried using SD Formatter/windows tools/phone) would only fix the problem for short time.
So which of the following in your opinion is the most reliable choice:
1. SAN DISK
2. PATRIOT
3. Kingston
4. ADATA
5. Transcend
6. Lexar
7. SONY
Also, what class (2,4,6 would be nice if someone could explain whats best and generally what it means). As well as capacity (whether it affects reliability)
No one buy the kingston class 4 4gb card, does not work well at all! I trashed it lol
i got a Class 10 Patriot card, works well, really well
Transcends 8gb Class 6!
Never had a problem with it
Hi, I am using transcend 8Gb card. I dont find any problem till now.
RiData 16GB Class 6
Been using it for 2 weeks. No issues.
Write & Read transfers are averaging 9mbs when transfering backups to and from.
Kingmax 8Gb Class 6, not bad
Don't buy transcend 8gb class 6 card in any situation, it has really bad power drainage problem in every build, after I swapped it with my friends verbatim class 4 8gb I have top 1 % per hour drain in standby, believe me.
Stock 16 gb san disk I got when I purchased my hd2, runs amazingly

Any way to check faulty micro sd?
Thanks everyone for the input, seems like I've either got a faulty SanDisk card or doing something wrong here. Are there any tools to test whether or not my 16Gb SanDisk micro sd is faulty or possibly corrupt... By the way, I got it off ebay for $20... seems fishy, although it came in original packagin brand new.
...
German TakeMS 4GB Class6, works like a charm...
Transcend 16gb class 6 runs Android with no hiccups at all and the transfer rate is blazing fast
Samsung 4Go Class 4, low battery drainage, performs like a class 6 card. Original style (grey coloured).
Battery consumption
Battery consumption on Transcend sucks if you want long battery life use sandisk or best by my tests 8gb class 4 Kingston.
i have 4 different sd cards kingston 4 gig class 2, 2 sandisk 4 gig , and a class 6 transcend 8 gig...and i always get better results with the stock card

Sd card don't have jack sh*$ to do with battery drain. As far as cards go, it don't matter. Just pick one. There all the same regardless if someone says this one is faster because it's a class 6, or 8. I have a class 2,4, and 8. No difference what so ever. Even though its written on the class 8 at a higher speed.
Any idea on why sometimes I find non-removable random symbol files on my SD? Does this indicate corruption?
German TakeMS 8gb class 6 extreme fast and stable.
beware buying microsd on ebay

As some people reported this sd card will cause multiple lags and slow down market place and app installing, others are saying its working fine for them.
Does someone know about a workaround?
Well I have a Kingstone 16GB card and I can confirm I am experiencing some lags while browsing & listening to music, i'm unsure of the installing speed issue since everyone on WP7 experience slow sync and slow deployment of XAP files, but it is terribly slow.
thinking on getting a new one just for WP7...
just test it without sd card for some time, its such a big difference
the question is if it can be fixed in some way or if its necessary to buy a completly new sd card
i've spent last two nights with installing wp7 on my kingston 8gb class 4 and my sandisk 2gb (hd2-bulk) over and over... my result: the 8gb kingston card is so much slower... not to speak about the annoying lags in marketplaas as described above and the multiple reboots on startup (up to 8 times till it boots all the way through to homescreen!) now i'm forced to stay on 2gb until a solution is found, or someone will sponsor a compatible 8gb card (or larger) to me

At least the 2GB sandisk works for you, i got 2 of them and none are even recognized
Well I have 2 more cards
one is a generic 4GB i tested WP7 with which was great! but I didn't cofirm if the slowdowns occur after installing apps and adding music, I only synced about 10 songs before deciding to install WP7 on my kingston one, so I can't confirm that it was better, it just didn't lag, I can't know if the lag is an issue after loading things onto the SD card.
The one SD card I have is another Kingston 8 GB, same model like my 16GB, so it would be stupid to even try it since i've got everything configured for now on my 16GB.
I'm thinking about getting a Sandisk 16GB but i'm afraid i'll just throw money and this issues will appear again because they are size related...
The thing is, Does everyone experince slow downs when listenning to music? (which is the main thing I do with my phone) or that WP7 doesn't load apps sometimes? or when sometimes you swype left for the list and the icons of the applications that are insatlled on the SD card are still loading (grey image with a star).
Facebook is slow.
Because if this is the base performance for everyone i'll just stay with my Kingston.
It just seems that everything that's related to the SD card is working on and off.
The Kingston 4GB class 4 I have is very laggy, big difference with it out. I bought one of those SD cards that where approved as WP7 compatible by Sandisk.
My HD2 is in repair at the moment getting a new digitizer so I can't test it until it comes back.

im experiencing the same, but as i said its probably related to the kingston sd card, its not the base performance
everything works awesomely fast without the sd card inserted...
Deploying applications takes ages, music in Zune stutters, games lag... It's clearly the bad performance of our Kingston...
I have 4 MicroSD :
sandisk 2gig class4
Sandisk 2gig class2
Kingston 4gig class2
Kingston 4gig class6
Sandisk 2gig class2 is the best.Class4 drain more battery and is more lag.
I have 2 MicroSD
kingston 16Go Class 2
kingston 8Go Class 4
16 c2 is perfect
8 c4 is lag and slowdown
Inersting but it seems all the laggy SD's are class 4, while class 2 works good, mine is a class 4 as well.
I have 2 MicroSD
Samsung 8GB Class 2 ( lag and slowdown )
Nokia 4GB Class 6 ( really fast and good battery )
I have a 16Gb Kingston class 4 and magldr doesn't even recognize it let alone wm7 I think its down to that, like the battery issues most are having, in time these will be fixed
I confirm, don't use Kingston class4 (I'll try to get a refund from amazon :/)
No problem with my sandisk class2
same here, 8GB class 4 Kingston doesn't even boot anything :-(
Yea I have a Kingston class 4 16gb that magldr doesn't even read, I have just put a post in the HD2 general about it asking about it

I don't know. But one of my friend using class 4 transcend sd card and he can play 720p videos. While i can't using Sandisc class 4.
Thanks bdw. I purchased it and it's working fine. Write speed is 9mbps and reading at 11-13mbps
Will try diff cache value.
Class 6 gives good performance. Having no problems since 3 months.
I use 32GB class 10 Lexar.
No problem at all.
I've been using a class 10 16GB TOPRAM card for almost a year, with no problems.
I use a Kingston Class10 16GB since a week ago and it's working fine so far. 9.1MB/s write and 19MB/s read on 2.3.6
Thanks for starting this thread
Im going to order a class 6, 8 gig samsung card for my defy from letsbuy.com
@darshan - bro, what is you say ? how are you finding your class 6 card in defy? how about 720p playback and HD gaming?? Is there any issue with day to day usage, like with camera app and something? Does it hang? or does it goes in to READ ONLY by any chance??
Btw, Im running on stock 2.2.2 without root.
Thanking you in advance
Hi,
I have class 4 SD card m running Pda's win7.8 rom. the problem I m facing is its lagging and slow then I did a benchmark test using free benchmark app everything is perfect except the write speed which is just 2.1 something, I know it may be a problem of SD card though wanted to know is there any tweak to speed it up through registry or app like andoirds have?
thankyou
no... buy better card...

Sandisk doing better than Samsung in SD, for higher performance, i use Sandisk UHS-I 8GB SD.
I used both NativeSD and DataonExt. My Scandisk Ultra 16G work fine.
Sandisk 10 class with UHS - hd2 incompatible
I tested 2 microsd cards(I bought in one place at once) with 2 different hd2.
first card worked with bouh hd2, but only 1-2 days => after freeze.
second card freezed at boot always, on both phones.
MD5 checksum was identical for both cards.
Both cards work very quickly with other devices without glitches.
Now i use 4.2.2 with transcend 10 class without UHS. HD2 is fast now, more than ever... A1 SD Bench: 18.9mb/s read, 10.5mb/s write.

I would strongly suggest checking out this thread.http://forum.xda-developers.com/showthread.php?t=1947560
My SanDisk 32gb class 6 card reads about 10mbs higher than yours. My suspicion is that it's your buffer size that needs to be adjusted, but that thread is one of the best resources for optimizing you're card.

Do you test speed by "SD Tools" ? In this programm my transcend show 33mb/s, but it's cached speed, i saw same speed on 2 class card.
I agree what sandisk very fast. But cards with UHS not worked with my both hd2(512mb EU and RU versions )
SDTools seems to be the XDA standard from most when testing you're SD card. I find it very accurate and reliable.
