When I moved the Dalvik-cache and /data/data to my SD card (class 4) my phone slowed down a little. I also had the apps and app-private on the SD card.
I then moved the dalvik-cache and /data/data back to the internal memory, and the speed came back and it was back to normal.
My question is which one really slowed down the phone. The /data/data moving to the SD card, or the dalvik-cache moving to the SD card. I suppose I'll save about 2 MB by moving /data/data back to the SD, but I'll save about 40 MB moving the dalvik back.
If I move the /data/data to the SD card, is this where the Browser cache is stored, or is the dalvik-cache. If anyone has a class 6 and has moved ALL cache and apps, do you get the lag when moving icons and things like that.
Thanks,
It's a MUCH better phone now, I should have done this months ago.!
Good question. I too have been interested to learn in the performance differences in having the data and cache on the SD card.
Dont move data. It causes the lag (e.g. when you move or add/delete an item on your homescreen!
dalvik+apps is more than enough and works like a charm with my class4 card
Same here lads, very interested in knowing what is beneficial for speed, my 8gb Sandisk Mobile Ultra class 6 should be here in a day or two (yay) and I'll be wiping, reinstalling JF1.5 and then sorting out apps to SD.
I have everything on an 8gb class 6. The speed seems to be just fine.
When I had the class4 with my apps, and cache on the SDCARD it was slower and crashed quite often. I got a high speed class6 and my phone is reliable as ever and just as fast. I have not had a crash since I went to the class6 and only had 1 force close which was after a update.
I am running dudes cupcake .93
I got over 150 apps installed
dalvik cache and data on the SDCARD
*Lucky* Got a class 2 8 GB microSDHC card with read-speed about 6 MB/S and write about 3 MB/S.
No Lags.
Just out of curiousity. What is the point of moving the Dalvik-cache besides trying to spare the phone from memory IO's on the internal flash (wear and tear on flash chips)?
Something I've wondered, does the phone use the 71mb free (if you move everything) for extra RAM or is it just free storage space as I thought it was. If it is just free storage space. There is no difference between 40megs and 71megs - people seem to have gotten increasingly obsessed with getting more and more "free space" on the phone.
Thanks a lot guys, it seems like this answered the question perfectly. It seems like the /data/data causes the problem on my class 4.
I suppose people with the class 6 can put Everything on the SD card.
About the guy with the class 2 and EVERYTHING on the SD card, what brand are you using, and can I get one?
About the browser cache etc . . . does dalvik-cache hold all that information? I suppose it does, and the /data/data are the actual System apps that run the phone for the most part. I'll keep those on the phone.
I hope moving the dalvik-cache doesn't require a re-sign in etc . . .
Thanks a lot.

Class 4
You should probably try to get your hands on a class 6 or higher (they do make a class 8 8gb - but it is not needed) Anything slower, you will see a lag. NewEgg sells one for 15 including SandH. Also I have been running the overclocker app and it is solid at 572.15. That may help you as well and the app works on 1.5 either JF or H's builds.
Hope that helps.
Ive got a Patriot 8g class 4 with apps2sd an dalvik-cache with no lag I haven't had any force close apps, Ive been running JF 1.5 and apps2sd since Saturday.
Thanks a lot, I'll look into the overclocker app. Which one in particular are you referring to?
As far as class 6 and below goes, I have good news. Just moved my dalvik-cache back to the SD card in recovery mode. Wiped it from my internal, got back roughly 30 MB, and NO LAG!
Whoever said it was /data/data that causes the lag is absolutely right. For me at least.
Now I'll move over a few select cache (browser / maps / market) to SD card also, to see if any speed hit comes on those apps. I'm now EVEN happier than before with 1.5 and a regular T Mobile G1. It's like a completely different phone. Only if OHIO would get 3G, then it'd be one of the nicer phones out there. Sorry for the rant, just feels good to have all this stuff working.

Hey,
i screwed it up somehow. my phone doesn't work anymore.
After installing the memory card and a hard reset it stops working during the installation.
it just says:
Code:
"INSTALLING APPS
A few more applications still need to finish installing. It should just take another moment or two."
i wait 40mins before i removed the batterie.
after this i try to restore my phone with zune to the NoDo restore point.
failed with error code: 80180090
But the phone restarts normally and my phone recognizes the 16Gb card.
but it doesn't feel smooth anymore. (for example it takes a long time to start enter the settings)
i was also able to connect my phone to zune.
Zune recognizes my sd card as well but when i try to sync Musik it throws an error (C00D124D) after a few songs.
it tryed a softreset but the result is still the same.
right now it shows the
Code:
"INSTALLING APPS
A few more applications still need to finish installing. It should just take another moment or two."
again
it is a vicious circle...
any other ideas?

Newegg's comments on the microSD 32 GB cards they offer rate the cards very low in general. Appearently quality assurance on these cards, or the cards themselves, are extremely flaky. Put the card in your PC and run a stress tester on it.
As for your original 16 GB that seems to be worse, try a hard reset. When changing the cards around, that could have something to do with it.
I used the 32GB card linked in my sig. It actually came in a red package that says for mobile devices. It also appears to be the EXACT same card as the 16GB that came in the phonem only difference is the capacity.
0 issues whatsoever, seems every bit as fast as stock if not a bit faster.
I had such problem with my old 16Gb Kingston Class 2. There were no any problems with installing apps, but phone was not smooth. And there were some problems with syncing Music, it was taken a long of time, and sometimes there were problems during the process.
So, I've installed my original SD 8Gb card, made another hard reset. Now it looks smooth and sync is fast. I decided not to change card anymore, but buy mp3 player with 32 or 64 Gb of memory. Because I don't like how this phone is playing music.
I've purchased a Wintech 32 GB microSD card from Newegg and plan on installing it in this, when I get my tri-wing screw driver set. So I'll let you know how that turns out.
Until then, I've ran just about every stress test I can find against it - and it has no issues. Note: I am not going to do a full format like others are, that seem to have issues in the long run. I am going to use it as the card came.
EDIT: Don't buy the Wintech for WP7.
i managed to bring my phone back to life by simply replacing the new card (Toshiba microSD card 16GB class 4) with the original card.
But 8 GB is a mess i will try it later with another sdcard.
Did anyone could recommend a 16GB/32GB card from a retailer in germany/europe?
Joel
For the record, I had issues as well with my 32 GB upgrade.
After some research, I now see that you should not be getting the highest class card. You need to focus on random access times. The Sandisk 32 GB microSDHC really is the card to get perhaps. Still a bet.
I'm ebaying my Wintect 32 GB class 10 to some Android user. For our WP7, it's all about how quickly you can find the fragmented data - not how fast you can read the data. Think, "need to find it fast enough, or the phone will reboot".
A month ago I ordered this item:
http://www.amazon.com/Lexar-MicroSD..._m=ATVPDKIKX0DER&pf_rd_r=1PQ8JS4R3GMEAF3KKA5X
Yesterday it arrived, a 32GB, Class 10 MicroSHDC.
Previously I had a Sandisk 16GB Class 2.
Today I'm gonna try it on my Nexus One and keep this thread updated regarding my experience with this card.
Let me post ATTO test result screenshot first
4 May 09:10am Partitioning it, 256MB swap, 2GB ext2, rest = FAT 32
4 May 09:24am Done an ATTO test on my old Sandisk 16GB Class 2 and upload screenshot
4 May 09:27am Preparing for a complete wipe on my Nexus One. Re-format 32GB card using 32KB allocation unit size. Using Windows Explorer to copy and paste music into it, speed is around 9.9MB/s
4 May 09:33am Writing is very steady, at around 9.85MB/s. Finger touched on the card, it's very hot I'm using Lexar card reader (which came with the card).
4 May 10:19am Just cleaned my phone (physically ) and copied lot of music into the card, gonna put it back into phone and do a clean wipe
4 May 10:59am System boots fine, configuring settings, no noticeable boot speed improvement since I have not installed any app yet.
4 May 11:13am Noticed that the phone's speed of installing & downloading multiple apps at once has increased significantly.
4 May 11:29am Installed about 30 apps system runs smoothly, no any problem so far.
4 May 05:19pm Has been running the phone for half a day, noticed no battery consumption difference, the SD card is stable.
5 May 18:25pm Today I installed more apps (185 in total), and started experiencing serious performance problem, system stuck when listening to music and installing multiple apps. Re-partitioned the SD card into 0 sawp, 1.2GB ext 4 and rest is Fat32, still using 32kb as allocation unit size. I'll see if the issue gets solved. By the way, the battery consumption of the new card seems to be equal as my previous Sandisk one.
6 May 08:47am After re-formatted the card last night and updated to the latest CM nightly, IR's kernel and Gapps, the issue seems to be little better, although it is still laggy to install more than 10 applications at once however the phone does not freeze anymore (so far). Probably 2GB ext partition was too big for DT app2SD?
8 May 10:03am Everything seems to be very stable and fast, partition configuration is: 1.2GB Ext2, 0 Swap, rest = FAT32 using 32KB file allocation unit size, have more than 200 apps installed now.
9 May 15:47pm Well, after installed totally 300 apps yesterday, the system has been not very responsive, applications often lose response and come back after a while, Market app sometimes lose response and crashes, system is pretty unstable. I was on Nightly #64, IR's 0506 kernel and Gapps 0503. I have just re-partitioned the SD card again, trying 1GB Ext2, 0 Swap, rest = FAT 32 and use 16KB as file allocation unit size. This time I'll use CM stable 7.0.3, IR's 0507 kernel and Gapps 0301, see if everything becomes OK.
10 May 13:15 Really tired of re-installing system for more than 4 times in just one week. The card initially performed well but now it just can not handle App2ext, Market app keeps crashing, application forces close and system reboots automatically multiple times every hour. But I don't plan to give up and go back to my old 16GB card yet, I'm seeking for a solution and I'm confident that Nexus One can handle a 32GB sd card.
11 May 09:00 Yesterday I thought about changing the partition characteristics. Eventually I formatted the card into 1.2GB Ext3, 0 Swap, rest = Fat32 using 64KB file allocation unit size and now the stability issue seems to have been resolved, no more force closes or system reboots. Is it the key that 64KB allocation unit size resolved the issue?
11 May 20:00 I've just re-installed (I can't remember how many times I've done this in the last 10 days) system, did a clean and complete wipe and re-partitioned SD card into 1GB Ext3 and rest = Fat32 using 64KB file allocation unit size. I feel like the reason of instability is now determined. Now I'm installing apps and will report back later on stability and make a conclusion with this Class 10 32GB card.
12 May 20:03
Now I can make a conclusion on how to correctly use this card on Nexus One.
There are two factors, which contributed to instability of my previous installs, one is CPU voltage, another is partition layout.
The new card seems to use a bit more voltage to work, that's why my phone became unable to use (reboots and FCs) after I applied my own voltage table (undervolt 100mV at each frequency compare to default table) with IntersectRaven's kernel. The card works fine with the default voltage table of IntersectRaven and CM's kernels.
However, that's not all.
Why the system was very unresponsive when installing many applications, and simple multi tasking would completely freeze the system? Another factor contributed to the issue: File allocation unit size. From the speed test screen shot we can see that the card achieves its best performance when block size is 64KB, that indicates that the card internally is formatted into 64KB blocks. I am still not sure why using 16KB or 32KB file allocation unit size for its FAT32 partition will cause system to be very unstable, however after using 64KB as file allocation unit size, the system runs very smooth and stable, now I'm happy with the card's speed and quality.
Current partition layout:
1 GB Ext 2
0 Swap
Rest = FAT 32 using 64KB as file allocation unit size
18 May
Re-partitioned into 1.5GB Ext2 (1GB was not enough for 400+ apps) and rest=FAT32, still using 64KB as file allocation unit size.
The card has been stable and noticeably fast with more than 400 apps installed.
9 Aug
This card has corrupted for about 7 times due to rapid random accessing by phone, and proven unstable for daily use. Do not use this card on your phone if you have more than 200 apps installed on Ext partition!
See this post for more details:

Good review!
Nice review.. I'm thinking of getting 32GB class 10 myself this'll help me lots.. hey can you tell me what speeds you get on usb mounting in android..not through recovery..Its frustrating to have USB writes less than an MB/s and have a class 10 card..
yeah that speed is very slow, no matter how good the card is, so i never use that way to transfer files i always take my SD out and put it into a card reader.
I actually tried pershoot's kernel right after the first post and then found it to be extremely good at USB transfers..even idling current is at an all time low..iR's and Redstar's used to give me about 105-115 mA on idle and screen on but pershoot's is giving 80-90!! and ROCK STABLE too!! no hiccups or jerky scrolling on any screen.. hell of an improvement..
may i ask if there is any difference in performance if the app partition is set as ext2, ext3, or ext4?
Thanks for the post. It got me going in the right direction.
32k clusters have mostly corrected the crashing and locking up my phone was doing with a new Wintec 32GB Class 10 card.
strangely If I create a file system in linux with
mkfs.vfat -s 32 -S 512 -n "Sdcard" /dev/sdc1 it results in 16k clusters..
mkfs.vfat -s 32 -S 1024 results in 32k clusters but windows XP can not access this file system and asks me to format
mkfs.vfat /dev/sdc1 results in 16k clusters
I had to use fat32format.exe on a windows machine to get 32k clusters with 512 bytes per logical sector that work both in Windows and Linux
so my question is how would I use mkfs.vfart to make a file system with 32k clusters that windows can read as well?
edit: my opinion on the ext question is that ext2 has a leg up on speed because it does not journal data and spends less time writing. however most people care about the integrity of there data and fsck is a terrible use of battery.. it seems the best of both worlds is ext4 with the mount options noatime,nodiratime,barrier=1,data=ordered as most roms now use

I'm so glad i came across your post, I have the same sdcard as yours and had exact same issues as you had post. I was starting to believe my phone is faulty until reading your post pin pointed to the problem.
So i Formatted with 64KB allocation size, 27GB FAT32, 2.5GB Ext4 and 500MB Swap. I can already tell the phone is snappier, gone the reboots , app freezes ..etc.
UPDATE:
So i jumped the gun. Having not done anything about the voltage table i'm seeing the Freezes/Reboots time and time again. @houzuoguo Where can i find a voltage table that will work with my SGS II KE7 CF-Root?

do you know... idle current should normally be below 20mAh, otherwise it means that your phone doesn't "sleep", something prevents it from sleeping... nightmares probably.
my phone uses about 4-9 mAh when idle.

i've read a lot of posts, people don't recommend using ext4 for flash storage since ext4 read/write more while enhance file system integrity, however i have not read anyone who says ext 4 runs slower.
these file systems are very much compatible with each other so basically i can say that their performance is very close.

I in fact have noticed that lowering voltage still works fine with the card, however previously i could lower voltage by 100mV, now i can only lower it by 75mV, and the card still runs stable.
i don't have a SGS2 (i really want one ) so i'm afraid that i don't know much about android development of the phone.
Voltage table is built into kernel, some kernels support you to modify voltage table, while some others do not. First you need to make sure that the kernel you're using supports customizable voltage-table. then i suggest you to look into your phone's kernel's code, find out the default voltage table, and make changes accordingly.
I've got the same card. I haven't noticed any bad issues. Phone is noticeably faster than with a class 4.

I am using Lexar 16GB Class 6 MicroSHDC. Transfer rate from PC by USB cable was ~ 1Mbyte/sec. Some days ago I installed CyanogenMod-7.1 for Nexus One and transfer rate dropped to ~700 Kbyte/sec. So you can try another ROM.
Well I just bought an ADATA 32GB class 10 and I’m having issues. It’s formatted fat32 w/the 32kb (did try 64kb) cluster, but any time I move data into the EXT3 or EXT4 partition that’s when the issues come up. I can use my ADATA 16GB class 10 without any problems. My ADATA 32GB class 4 just went bad, so that’s RMA. There were never any issues with that card. I did have a Patriot 32GB class 10 for a while, but lost it & that one never worked out either. If anyone has any other ideas I should try before I return this card, I'll try it.
UPDATE: Official response from ADATA “ split partitions are not guaranteed, EXT as a secondary partition is very complicated..”

Class 10 sd cards are no good for smart phones so you'll always get sub par results. Class 6 is the highest you should go for best results

64kb cluster size?
What tool are you using to adjust the cluster size to 64kb? I've got a couple SD card formatting utilities but I don't see that option anywhere, and they seem to default to 32kb.
Thanks
I've been reading that the higher class SDHC cards like class 6, 10 aren't great for random write access, small blocks, but since we run our OS/apps on the phone's internal memory and we don't do the A2SD+ stuff, should it be ok to use class 10 cards?
Or does android still do a lot of significant random access on SD cards for the sensation?
Class 10!
I use a 32GB class 10 with nearly all my apps stored on there. I don't suffer and read / write lag. All I'd say is you get what you pay for, so don't buy a cheap one
I understand but do you know if the OS does the random r/w on sdcard? I'm not running any a2sd for my apps or anything so AFAIK I could run my phone without an SD card...
well since gingerbread came out app2sd is integrated into the OS, so you can transfer your apps to your SD card or they can be internally stored
just go to settings>applications>manage applications then tap into any app (thats not a system app) and you can move it to your SD card o to the phone
?????
I'm not asking about transferring apps to SD card?!
I'm asking if the random read/write access matters since our OS and apps are on the internal 4GB memory of the phone. Does the OS use the sdcard for any operations at all?
i read somewhere in the forums that class 4 will suffice. class 10 suits those HD camcorders as the write speed is high. if i'm not wrong, the read speed is the same for all (don't blame me if i'm wrong though)
I'm actually also wondering about this. Since the sensation can record 1080p, does that mean we need a fast writing card for our phone?
I have just bought a 32GB class 4 Sandisk micro SD (£28.99 Ebay) and i have no problems at all recording video at [email protected] Mbps. It may seem slightly jerky when you are actually filming on screen but when you play it back its smmmooottthhh!! Don't buy cheap memory cards. YOU WILL REGRET IT and waste your hard earned cash!! Just a personal experience warning.

I agree. I have a 32gb class 4 sandisk and also a 32gb class 10 lexar and both record perfectly fine (smooth recording and playback). I'm using Amaze Cam v7 with 16mb bitrate. So if it can record and playback (via connecting to USB to computer and playing on PC) smoothly, then it is more than fast enough to run the apps and constant writing apps.

Hello all,
Any help would be very very much appreciated...
I am brand new to the Android world (2 months) and have been following this forum since. I have figured out how to flash my verizon model s7 to the universal, have figured out the best case and best glass screen protector.... I have even read extensively on SD cards and their speeds and the differences between adoptable and rooting....
Here's my question: I am an excessive app user, and yes I know the solution to this is to delete the apps I don't use....
But, I would really like to just store apps on my SD card and run them off of the card
I originally bought a SanDisk Ultra 200GB and a SD Extreme 128GB..... but upon further investigation I'm kind of feeling overwhelmed on what to do and which SD to buy.
From what I can find out there are two options for this:
Adoptable:
But, it's kind of buggy.
I don't want my entire phone, pictures, etc migrated over to the SD, just the ability to fully install apps
There are limitations to which apps can be migrated to the SD card
Best to have a faster SD card versus size, but there is still a significant bottleneck, UHSII doesn't work on this phone... so the SD Extreme or faster is best.
Root (Link2SD etc):
The Root for this phone is very buggy and I have seen quite a few go back to stock. And I don't want to trip KNOX quite yet... still under warranty.
Can move any app to my SD!!
SD doesn't need to be fast as long as I don't mind my apps loading slowly (or transfer the used ones to internal...)
Is there in-game lag, after loading, running from a slower SD such as the SanDisk Ultra?
I am full of competing ideas and the wealth of information on this forum and elsewhere is overwhelming me. I have spend over 20 hours in the last couple weeks researching this issue alone....
Please, any and all guidance and help would be very very appreciated. Thank you!
What did you choose at the end?
Hello! I chose the SD extreme 128. Upon further investigation it seems you cant truly install and run apps, app data and all from the SD card with adoptable, the only way to do that is with root access. So I went for the faster sd which put up really gread numbers. There is an SD card discussion I also posted in with my results and they beat the other same tier cards and rival some of the more expensive ones. I use the card mosty for 3D movies for my gear vr and have put a lot of apps on it (not tbe data of course which takes up the most space). I am awaitkng the day my Samsung warranty expires to root because 32 GB kinda sucks.
However, it would be safer to go with the faster card for adoptable anyway.
Also, I can record HD video directly to it while the 200GB cannot do that.
I'm planning to buy a 64GB memory card for HTC A9 and bind it as its internal memory. Could you guys suggest on this?
1. If anyone is using 64GB card, can you advise what are the specs I need to look it? I have read couple of reviews and seems "SAMAUNG -EVO + and SAMSUNG -EVO-" to be good. Any further suggestions?
2. Is it ok to bind the 64 memory as internal memory and does it work without any problems?

FYI, using a PNY U3 Pro Elite card without any issues. It's one of the fastest out there for the money. I did not bind it as internal memory though, and just use it as a secondary storage just in case (that way I can always remove it and still access thru a card reader on computer).
if you are looking to format as Internal Memory; UHS II, Speed Class 10
otherwise; UHS I, Speed Class 10

Thanks for the info !!
I had loads of problems with this (gone through 3 super fast SD cards... with each install the software would say it was not fast enough. Just ignore it ... the software lies). For almost a year it worked fine and then I ran out of memory space for apps, and I had to constantly delete apps to make room for updates. Finally I was forced to do a factory reset. Setting the SD memory card up after a factory reset means that you can create extended memory from scratch and allows you to put all the apps where the developer has given permission to run from the SD card onto the extended memory. After factory reset and going through and moving apps to extended memory everything has worked great.
I'm using "SanDisk Extreme PLUS 64 GB microSDXC" formated as internal Storage.
No Problems so far
