CrystalDiskMark

Hello,

have you tried 'CrystalDiskMark' for benchmarking the MicroSD-Card? It runs under Windows and has a benchmark for 4k blocks (which are important for ext3/ext4 file systems).

Yesterday, my new SanDisk MicroSD card arrived and i tested all of my Cards. The results (all values in MB/s, the 4K entries are the interesting ones) are

SanDisk 16G Ultra Class 10 Micro SDHC (my new card)

Read: 18.76

Write: 11.92

Read 4K: 3.2

Write 4K: 1.54

SanDisk 4G Class 4 Micro SD (this card was originally delivered with my HTC Desire)

Read: 10.59

Write: 3.05

Read 4K: 0.9

Write 4K: 0.47

Tanscend 16G Class 4 Micro SDHC

Read: 18.65

Write: 4.85

Read 4K: 2.64

Write 4K: 1.26

Tanscend 16G Class 10 Micro SDHC (my actual used card)

Read: 16.47

Write: 16.07

Read 4K: 3.4

Write 4K: 0.027

As you can see on the last card, writing can be very slow on small blocks. I think, the internal block size on the most bigger class 10 cards is not optimized for small, but for big blocks. These behaviour is also documented here: http://xdaforums.com/showpost.php?p=29365127&postcount=6827

Also, the partitions must be aligned to 4k. I did this by using the Linux fdisk for partitioning directly (sorry, all in german)

As you can see, the sector size is 512 Byte, so for a 4K alignment, the sector number must be divisible by 8.

I'm using sandisk 16GB class 6 and still okay for desire
[Desire Accessories] Mika83AC:
Currently i'm using a "16 GB Poppstar Micro SDHC Class6" and it's working fine as a sd-ext in ext3. Cheap and good value for the money.
[Desire Accessories] stifu:
Samsung Class10 Micro Sd, partitioning with 4ext recovery. Everithing went fine and fast.
[Desire Accessories] Mato_K:
Transcend 16gb class 6 do the best job for me but I usually format the card with 4ext before flash new rom
[Desire Accessories] vBurak:
Hello,

I'm sorry that I answer only now. I forgot this problem with my sd card totally :). Thanks for the recommendation, I will look for a Samsung SD Card or another SanDisk SD Card Class 4. Maybe it has some problem with this Ultra MicroSDHC cards....

I use 4ext recovery touch and did the partition with it. I checked the alignment too. I tried to partition the sd card with GParted by myself, but it failed as I wanted to install the ROM. I don't know what matter was.

Thanks.
[Desire Accessories] nonline:
You should look for a Class 10 (x150, up to 20MB/s read and up to 15MB/s write), mine emtec 8GB has been bought for $15 with adapter and 5 years manufacturers warranty. Working great in Desire :)
[Desire Accessories] Hiridur:
I have some Kingston 16 Gb class 4 micro SDHC and it's ok even if I use data2sd, int2ext and such.
[Desire Accessories] captain67:
No, class 10 is designed for recording high definition video. Class 4 and 6 are the most compatible with the Android operating system, and the apps used by it.

Try reading the thread, or actually doing some research before you attempt to make recommendations.

[Desire Accessories] vBurak:
I have now Samsung Class 10 16GB Micro SD Card and it works well. I use some modded a2sd script (lx2sd or something i don't know) and everything is on the sd card except dalvik cache. If I open some apps I have to wait 2-3 seconds but it's no big deal.

I didn't find any class 6 sd card from samsung, so I took the class 10. random 4 write was really low like 0,03 mb/s but now i have it and I don't care anymore ;).
[Desire Accessories] island3r:
That is not entirely true. That random 4k read/write speed is just a benchmark. Who told you that the .dex files are scattered in random blocks on the sd-ext? 99% of the time they are not. That's where the sequential speed kicks in and that's why anyone who uses a class10 over a class 4 sees a huge improvement in responsiveness.

Plus, no lag on 720p recording with sense roms. That's just a bonus.
[Desire Accessories] Snusmumr:
I'm using a Transcend 16 GB class 10 card. The card is working very good as sd-ext with ext4 partition
[Desire Accessories] danerty:
I'm using a Samsung 32 GB class 10 card and I have no problem
[Desire Accessories] Sivra:
I'm gonna perform necromancy ritual on this thread :D.

I'm thinking about buying one of these SD cards

Samsung Evo 16 GB

http://www.amazon.co.uk/gp/product/B00J2973JG/ref=noref?ie=UTF8&psc=1&s=electronics-accessories

or

Sandisk Ultra 16GB

http://www.amazon.co.uk/gp/product/B007JTKKOG/ref=noref?ie=UTF8&psc=1&s=electronics-accessories

Any recommendations? What do you think, which one would be better for kitkat rom and A2SD?

Thanks
[Desire Accessories] SaySayonara:
I'm using this one and I have to say I am very impressed and satisfied with it:

[Desire Accessories] bl0ndynek:
I would recommend don't use A2SD removed it and install some CronMod Script for example INIT2EXT
[Desire Accessories] Valerio-M8:
use samsung cards! great value and high reliability! the 8 and 16 gb card cost less than 10$
[Desire Accessories] Saf98:
Something with 6 or 10.
[Desire Accessories] Osmoso:
Sony class 4 8 gb
[Desire Accessories] wildchill:
Ive used a mix of cards from Samsung, Sandisk, Patriot.... and Ive never had any problems.

However I felt they all seem to perform roughly the same.

Such that a Class 10 card didnt seem to make apps n pics to load any faster than a Class 4 card.

I suspect its just a limitation of such a dated phone.
[Desire Accessories] stratoll:
There was a whole thread dedicated to sd cards that I participated in a long time ago. I would just like to say that sandisk gave me problems by automatically unmounting itself because it had more than one partitions on it. Therefore my HTC desire would freeze on supernova as files on my sd card could not be accessed. So I bought a transcend 32GB class 10. I still have that very same card albeit a different phone and never gave me any problems. Plus it was cheaper than sandisk so win win

Hello dear Note owners

Just joined the party

an of couse i am looking for lite rom - for note with great battery life

i moved from sgs1 vibrant where the best rom is miui 2.3.7 360 team

so as i readed on the note 2.3 is better for battery too..

and what are the best lite rom (dont like aps and etc anyway need to configure myself)
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] Thai Damen:
battery life is not really depending on rom.. it depend on the kernal n modem too..

basically from what i read here.. i think speedmod is great for smoothness n speed n battery life.. n lpt is good of signals.. try Kingdroid v4.1.1 watch their installation video before you stall installing
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] little-vince:
+1 speedmod kernel.

you could give checkrom a try too seeing as you're on gb.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] dcdancruz:
Used KingDroid v3 + speedmod kernel = just fine

Using RocketRom v7 + speedmod kernel = almost perfect on performance and batt life. Except for issues on lag using s.memo after making a screenshot. Other than that,

RocketRom v7 for me is a good go.

[Motorola Photon 4G] bjvanwash:
I've already installed the bootstrap recovery and it's working fine, however, I have a question about doing a nandroid backup. When I go to the backup/restore option, I only have 2 options. I believe the options are for the sdcard and the external sdcard. I'm not sure at the moment which one I chose at the time, but the backup files are as listed:

.android_secure.img, cache.img, data.img, nandroid.md5, and system.img

It seems like I'm missing a file, such as boot.img or something else and I don't want to install a custom rom for bootstrap before I know for sure. Also, in the recovery mode, I didn't see an option to nandroid restore.

Can someone explain this?
[Motorola Photon 4G] rbeavers:
I back up to the external sdcard it can be removed and has more free space.

Boot strap recovery is not the full CWR and doesn't back up all the system files. (I am pretty sure)
[Motorola Photon 4G] bjvanwash:
I know its not the full version of CWR but I was thinking I could do a nandroid backup like normal.

I don't really want to unlock the bootloader yet as I'm in a 4G area.
[Motorola Photon 4G] mof9336:
The CWM recovery in the bootstrap is an older version and does not back up the boot.img.
[Motorola Photon 4G] bjvanwash:
Thanks for your help guys. I may just unlock the bootloader and get a real version of CWM. I just hate to break my 4G.
[Samsung Infuse 4G] Ty113096:
ok im making a custom rom and i flashed it through CWM and everything was working except for a couple bugs here and there nothing major then i added aroma installer to the rom. I flashed using aroma everything booted up and now everything went back to the cm9 base instead of my rom. Any ideas what happened/whats wrong?
[Samsung Infuse 4G] vulle5:
i have problem when i try to install any rom whit aroma installer i get stuck to 1% then it says installation completed and it boots to my old rom what,s the problem
[Samsung Infuse 4G] Whizzpopper:
Was this with Th3Bill's CNA rom by any chance?
[Samsung Infuse 4G] mg2195:
I know very little about aroma...but,

You have edited the updater script to match the options in aroma right?

Chances are the aroma is recognizing the choices but the actuall updater script isn't because it isn't matching the aroma options...so its just flashing the base stuff instead if all your options
[Samsung Infuse 4G] JustinOkay:
GB Kernel

Flash a GB kernel before you use any aroma installer. From my experience I've ran into many issues with some ICS kernels and all GB kernels.

You can use SGS Kernal Flasher from the marketplace to back up and flash kernels.

Hope this helped.
[Samsung Infuse 4G] seamo123:
Same story here, I ALWAYS have problems whenever I have to use AROMA to install a ROM. AROMA sucks - CWM mightn't be as pretty but at least it works!

Checking betterbatterystats shows that mediascannerservice is preventing my phone from sleeping under partial wakelocks. How can I fix this?
[Samsung Galaxy Nexus] Jubakuba:
Fairly Certain that's a signal search.

I get the same thing at work where nobody gets service...

You're probably in an area with bad signal...and not much you can do, really.
[Samsung Galaxy Nexus] gadgetluva:
My phone gets excellent service here at work and at home, so I know that can't be it. Plus, there's a different section for it under the battery stats.
[Samsung Galaxy Nexus] killyouridols:
Reboot. Usually happens to me once in a while. I think its the OS scanning /sdcard for music, pics etc.
[Samsung Galaxy Nexus] Jubakuba:

Media scanner will run while music is playing as well.

[Samsung Galaxy Nexus] gadgetluva:
I saw this behavior the other day, hopefully this reboot fixes it. Will keep an eye on it and investigate further if need be. Thanks!
[Samsung Galaxy Nexus] gadgetluva:
It seems that the problem keeps on popping up as mediascannerservice continues to be at the top of my battery usage. Any other tips on how to correct?
[Samsung Galaxy Nexus] maw230:
This service is killing my battery. I've read that it could be a corrupt media file causing the device to constantly scan for media. I;m just going to delete a bunch of **** and see if that helps, because i haven't found any fixes yet.
[Samsung Galaxy Nexus] paulr24:
I'm experiencing the same issue on both my GSM Gnex and Nexus 7. I don't even really have any media files on either of them at the moment besides the stock ring tones and that sort of thing. I don't know if it's an app misbehaving or what. Pretty annoying, but what I'm doing as a temporary "fix" is going to settings > apps > running and stopping the media process. I need to do this every time I reboot.
[Samsung Galaxy Nexus] maw230:
Hmmm, if you dont have many media files then maybe thats not the cause at all. Are you running stock android on both?
[Samsung Galaxy Nexus] paulr24:
I'm completely stock but rooted on the Nexus 7, and on the Gnex I'm running Liquidsmooth JB beta 1 with Trinity kernel. Last night I let my Nexus 7 battery drain instead of stopping the media service hoping this issue would stop after it was done scanning, and it did stop after a few hours, but as soon as I rebooted it was back. The only files I can think of that could be corrupt would be my Titanium Backup data (would make sense since I have the same backups on both devices), and I did restore some apps/settings. I may try a full wipe soon and see what happens from there.
[Samsung Galaxy Nexus] madd0g:
You probably have corrupted images/media on the SD. Move all the stuff and test it out.
[Samsung Galaxy Nexus] maw230:
Let me know if a full wipe fixes it. I'm not in the mood to do all that work atm. I haven't noticed any problems on my N7 just my Gnex.

Edit - also fwiw, my Gnex is having the problem where it thinks it's charging when it's not plugged in and it switches back and forth constantly. im not sure if that would effect the media service.
[Samsung Galaxy Nexus] paulr24:
So I ended up doing a full wipe of my Nexus 7 that was experiencing this issue (left everything on the sd card though) and flashed Paranoid Android 1.95a. I then restored all of my apps and app data with TiBu and I'm having no issue with the mediascannerservice wakelock.
[Samsung Galaxy Nexus] paulr24:
Does anyone know about how long mediascannerservice is supposed to run for after each boot? It actually looks like it's running for an hour to an hour and a half on both of my devices (I performed a full wipe and flashed MiNCO rom on my Gnex) and then it stops and everything is good until the next time I reboot. Seems like an hour to an hour and a half is still more time than should be necessary, considering my battery is getting killed during this time. Adding a .nomedia file to the root of my SD card hasn't helped at all either.
[Samsung Galaxy Nexus] DrHenley:
See my thread about this here:

http://xdaforums.com/showthread.php?t=1801378

Removed the files and it stopped.

Renamed the folders and it stopped cold.

I've found this topic very useful indeed.

I seem to have fixed the problem by deleting the flickr app's photos folder. I was using flickr yesterday while on a train with a very bad signal, and i think it left me with corrupt image files. I've then put a .nomedia file in the folder to stop it happening.

Just redownload your rom and extract the files you need and push them or reflash your current rom, just wiping cache partition/dalvik cache.

But if you are not sure you have deleted the files...

For the build.prop look in system/build.prop,for the build.pro...?

If noone else is able to help you, maybe just flash the stock ROM found here from Google? NOTE: you have to download and flash the mysid one as that's the one for the Verizon GNex.

If it's not deteriorating anything, you may as well consider leaving it and then doing something when it really does break something.

To All, Hey members. Im new to the community but have been a avid follow of this site for quite some time now. I am pretty tech savy and feel like I can fix this problem. The problem being this: I have a sensation 4g from tmobile that was given to me cause someone attempted to root it and couldnt get it done. So as of right now, I can get to the bootloader screen and it has recovery 4xt as well. I have yet to root a device but have been researching it quite thoroughly on here and with the phone being in the state its in, i felt rather opposed to ask instead of taking initiative and risking bricking the device.

As listed on bootloader screen:

On the SDcard i was able to see the two roms and the other file listed below.

Elegancia_ICS_TMOUS_V3.0.0

Android_Revolution_HD-Sensation_6.6.7

So where can I can from here?? I feel like theres something i can do to pick up where the previous person left off, or maybe start over possibly.

Im open to all feedback and would appreciate the help to further my knowledge of Android devices and rooting in a whole :) To add, I have not installed anything to my laptop at this time.

I went to bed with about 50% power left in my KF but got woken up by a ping in the morning. Pressed the power button and I see a notice saying power is down to 12%. Do all ICS ROM currently function like this which the power button only turns off the screen but not the device? I never had an issue with CM7 and Modoco ROM. Should I just turn off WIFI before soft power off to save battery? Seem kind of silly to sit there and wait for the device to reboot into recovery and shutdown from there.
