ok.. im a noob at this... bt what is SWAP partition??? how does its size effect the performance??
It's a partition on your device that the system use when the RAM is full.
so if its grater in size.... that means its good... right??
and if so.. then y do devs prefer to keep it as 0mb??
Beceause it's easier to maintain it i suppose ^^
Its because there is no need for swap and it can reduce the life of your sd card, according to most ppl

But remember, swap partition will never be fast like device ram chip.
And if u want to achieve good performance witch swap partition, buy microsd card class 6 (not 4)
good luck
Or use the stock class 2 card

ok... how do i check the class of by card?? coz here in India they dont provide class info along eith the card... also there is nothing written on it.... my card gives me a decent transfer rate of 4-5 mbps while copying to the card...
Class 4, it give me 10mb writing speed
Sent from my HTC Wildfire using XDA App
then i'd say mine is class 2(4-5 mbps while copying pc to sd, where as 9-10 mbps while copying 4m sd to pc)??? any software that could assure me??
interesting I have 8GB sd card class 4 and writing speed is 2mb max... is anything wrong? ****

Either u have been fooled, or its a problem with ur Pc(coz my class2 card gives me 4MBPS),
or the number of files is too large
Example :- 1 file of 100MB will copy faster than 100 files of 1MB each...

Hi,
Has anyone tried either the Lexar or Patriot 32GB microSDHC card with their Droid/Milestones?
Any issues at all?
Thanks!
Any information at all would be appreciated.
I haven't been able to find any information by searching forums.
I am running Cyanogen 6, 2.2.1, so I should be able to format the 32GB card. I'm just concerned with compatibility issues with the original Droid 1 and the Milestone.
Anyone?
Thanks!
this would be interesting for me too. im searching a 32 gb card which is workin!
yeah, would love to hear something about 32gb goodness too ^^
Yeah I'm surprised that we aren't getting more feedback with this topic.
I've found threads with 32GB cards with EVOs and Droid Xs, but, that's about it.
I think it helps if you manage to get it formatted properly, either on a desktop computer or on your device (if it supports it).
I'm tempted by the Patriot 32GB Class 10, but, some of the people on Newegg seemed to have some issues with it on a their Droid Xs.

Do you experience any subjective speed increases with the new card?
Have you run any SD Card speed tests with the card? If not, would you mind doing so and reporting back?
Just wondering if the Milestone will benefit from a class 10 card (or any card greater than class 2).
Thanks again!
i got 8.8MB/s write speed and 12.7MB/s read using antutu system review btw im also using apps2ext and cm7. I dont know by using apps2ext if the benchmark is effected. I was using a 16gb class 2 Kingston card before this and generally haven't noticed much of a speed difference but I mainly use the card for music
Edit: SD tools gets 10.6MB/s writing speed and 14.4MB/s reading speed

Hi,
Thanks for sharing your results. Those performance speeds are quite attractive!
I'm surprised that you you don't feel any subjective speed increases though. I would have thought that when accessing applications stored on your SD card, or when you initially remount your SD card and have to search through media using Gallery, that the difference would have been significant.
Although it is possible that our phones doesn't support much more than Class 2 speeds.
But, at least we know that the Lexar card is compatible with the Droid/Milestone!
Thanks very much for the information!

Class 2 is (roughly speaking) 2MB/s writing speed. Imagine you want to copy a lot of mp3's or a movie (or use it as USB dongle) with 2MB/s. unusable.

Oh sure, I understand that a faster card will make file transfers with my desktop much faster. I guess I was hoping to get more of a performance boost from my phone (ie. Apps2SD) with a faster card.
I'm not sure I'd call 2MB/S unusable for desktop file transfers. But, then again I don't change the music on my phone more than once a month. I can see it being more troublesome if you changed it more regularly. And hey, more speed is always good
Something else to consider - I have an 8GB class 2 card.
Loading angry birds seasons from my SD card = 15 seconds

Yes, that's a great point. I just don't know if the Droid/Milestone can take advantage of a microSDHC card with a higher transfer rate than Class 2.
Have you tried a faster card with your phone?
Does anyone have any comparison numbers with faster cards and application loading using Apps2SD?
Thanks!

Is anyone using the Patriot 32GB with a Droid/Milestone?
With the Milestone SD card which came with the phone (I think this is a UK retail version) "OEM SD SU08G", I got these results:
3.8 / 14.8 MB/s
I added this simply to have something to compare with.

Hi,
Thanks for sharing your results!
You're the first person I've heard of who is using this combination. Your speed test results are very impressive.
May I ask you to clarify your comment regarding reboots? Do you mean that if you move large files, or a large quantity of files from your PC to your Milestone, that you have been experiencing reboots? What other issues have you been experiencing?
Have you noticed any kind of speed increase?
Thanks!

In my place, there are many persons who are using this sdhc, so don't worry MS can support it.
In our experenice from our fourm, some MS work great and nothing happened.
But, some MS including my MS have the problem about reboot, app exit when you are using it, if you move a large quantity of files once a time from PC to MS.
There is also a problem from my experenice, not for all others.
My MS could not identify the SD card, or need to format the Sd card.
In this situation, the SD card repairation by some sd format app could be settle the problem, and then the card is back. The information of the repairation shows that there are some unknow link, bad sector, or error link. When I look further, I find the files that often appear above three error message are in the below folders /sdcard/LOST.DIR and /sdcard/LazyList. Thus I think these are the reason why the problem happens.
There is an interesting thing. I have fat and ext partitions in my card, but the partition of ext never has any problems. Last month, I format the fat32 by 64K formation, and it works well so far. (someone prefers 32K)
The speed increase. Yes, but not so significantly. I feel the system is more smooth. The delay when open the app is also less, but you know the speed also involve the size of memory. So, it's haven't extreme different.
i upgraded to a new SD card and run antutu to see how fast it is but to my surprise this new class 10 card is not faster than my old class 2 card.
so is there like a hardware limit or why could that be?
both cards have about
6mb/s write and
15mb/s read.
anyone got some better results with a class 10 card?

Hi, with my 16GB Class 10 card I get these speeds;

My card is a no brand card I bought from eBay in March for £16.

I have a Samsung Plus 16GB Class 10 and get:
According to SD Tools: 12.4MB/s write and 17.2 MB/s read.
According to AnTuTu: 11.3 MB/s write and 14.7 MB/s read.
16GB Sandisk Class 10 (Antutu 2.3.1, 2nd run.)
10.4 MB/s Read
10.0 MB/s Write
The card has 12.4 GB on it of real data before testing.
This is on GR3, which I don't think has any "SD-Card optimization". (Too lazy to check.)
Keep in mind that we don't know, at least I don't, how Antutu tests. If it's testing with a lot of independent reads/writes, the speed will invariably go down. (If copying a single large file from my computer, I get a much higher throughput.)
"Class 10" should only mean that your card is able to sustain 10MB/s of continuous writes, it doesn't say anything about access times/block erase speed (which can influence any benchmark.)
Hi TrymHansen, there is a free app called SD Tools which does nothing but test SD card speeds.
Edit:
FOR ANYBODY ELSE READING THIS THREAD:
The class rating of a card indicates the minimum speed the card will write at. Class 10 = 10 MB/s write speed. Read speeds are usually higher than write speeds.
Anil
Excuse me for being dense, but I don't get the point of your post. I explained in my post what Class 10 means, and then you post as if I asked what class 10 means.

My post wasn't only for you. The first part about SD Tools pertains to you. And anyway your post is incorrect, the Class rating indicates the MINIMUM speed the card will write at. Which isn't the same as a sustained speed.

I can confirm the quality of Kingston SD cards. My 16GB "Class 10" gets the following in SD Tools:
Writing Speed: 7.2MM/s
Reading Speed 13.5MB/s
It's good enough for me as I was considering just getting a Class 6 as I don't exactly do much HD video recording, but if you need the speed - avoid this card!
I am using Sandisk 32gb class 4 card.
Antutu Benchmark
SD card write: 5.6 MB/S
SD card read: 8.9 MB/s
Your SD Cache size matters when u perform SD Speed test in your phone. If you are using CM7 ROM, the default is a mere 128kb cache.
Cache size of SD can be from 128kb to 4096kb and different sd cards will perform better/worst with different cache sizes.
Just thought it would be a good info to share.
why is it that im getting two diff figures when i test my card with antutu and sd tools?
sd tools - read 33MBs
write 6.1MBs
antutu read 10MBs
write 2.6MBs
something doesnt add up
sd read is 2046 default on miui rom
my card is a ridata 8gb class 10
which figure could be correct?

This is sort of true, but if it was a mere cache it would always be a good idea to set it as large as you can afford RAM-wize. This is not the case.
It is a read-ahead cache. In short that means that whenever a read is requested, it first checks the cache to see if the data is already there, if not it reads the amount of bytes specified no matter what.
Increasing the read-ahead cache will help when reading large files, since it leads to fewer (actual) io-commands being executed.
However, if you're reading a lot of small files it will hurt performance, since for every read issued it will read a lot of unnecessary data before it can go on to the next request.
(I also think this is at a block-level, which means that it merely reads the next blocks, not knowing if they actually belong to the file you're reading at the moment, but not sure about that.)

I'm looking forward into upgrading my SD Card, right now it's the default CLASS 2 with 2gb. I pretend to buy a 16gb class 10 one, from Adata.
But I need to know some things first. The only reasons that I want to upgrade is to get more space to install apps, place musics and maybe expand my RAM a little.
So, is it possible to expand my ram? I don't want performance upgrade, it's just that I tend to multitask a lot of programs and my memory runs out really fast.
If so, how much more memory I can allocate on my SD?
Same for apps.
How much big can my apps partition be?
I saw that the recommended limit is something around 1.2/1.3gb, but is there a safe way to expand a little bit further? Or would it make the phone too much unstable?
And also, is it really worth it to upgrade my SD to a CLASS 10 one with 16gb? Or is it just a waste of money?
Thanks for the support and excuse me if I'm asking on the wrong section/way. I found somethings about it but there was nothing too much concrete. :/
EDIT
I just flashed my X8 with the latest firmware and baseband, as pc companion didn't want to install the baseband ..15 nor the newest drivers. Also installed the CM7, dualtouch and all that crap. It already installs apps to the SD and I've noticed a small slowdown on app startup. Would a class 10 sd soft it out?
Up to 200MB on SWAP partition, up to 2GB on apps EXT3/4 (any1 have so many of them???) rest for music/videos etc.
I have made a guide for partitioning the SD with ext+swap (you need AlfsKernel+GDX)
Look my signature
Thanks. But just another question. Is it really necessary to have a Class 10 SD card, or would Class 2 (the default one) slow things down while using swap?
Edit:
Also, a class 10 sd card is way too much expensive for me. I found a 16gb one, class 4 but it's SDHC. Will my X8 read a SDHC?
Everything above (and including) 4GB is sdhc, so yes, it reads them fine. About speed, yes it's important, apps will load faster.. but never amazingly fast. The X8 is slow nowadays, don't expect awesome results. If you are used to class 2 speeds and you buy a class 10 card then yes, you will notice improvement.. Not that much with a class 4. Do you really need a 16GB card? Maybe a 8GB class 8 or 10 would be better if you don't need that much space.
About adding more ram, just forget it

Hi all, I have a couple of questions before I get my new sd-card.
1. I got my eyes on the SanDisk Ultra UHS-1 8gb class 10 sdcard with a write speed of 30mb/s(advertised). I was just wondering if there would be a noticeable speed difference (i.e. App loading time) if I partitioned that sdcard, as compared to my current class 4 Kingston sdcard.
2. Also, I've read from many forums that some devices don't see noticeable increase in speed from class 6 onwards... Is that true for our device too? (SGM)
3. Is ext4 partition better or ext3 partition better?

1. Well u surely won't get the advertised mb/s, but it will be a reasonably fast speed, as speed depends on your cable too (for trasnfer). I'm not sure, but yes u will notice that apps load faster (im basing this on what michie said in the swapping section of the performance thread, so its probably the same for loading from external partition)
2. Yes probably little difference between a class 6, 8 and 10. Maybe because most devices can't read beyond a certain speed or even if they do, that threshold speed is enough and lies in the range of class 6 upwards.
3. I don't really know, but i would suggest ext 4 as i see it recommended in many app to sd apps. Someone could clarify this.

Try Sd tools free on playstore to test your sd speed write/read before partition
(I try Speed Write true normal like sd class : 10Mb/s (class 10)
and test again after partition.
(I Test it & The Result Sd speed write reduce to 8Mb/s after partition but sd read Increase, test on my sd class 10)
If you want to boost more speed you can try free app called sd booster on playstore.

So buying a class10 sdcard does help increase the apploading speed in a2sd?
Maybe yes maybe no? some sd different so you must try in my case. yes the speed reduce.
From 10 to 8Mb/s
but Read Speed Increase from 23Mb/s to 28Mb/s
if I use sd booster and set it on 6Mb. my sd write reduce to 6.8 mb but Read speed increase to 32,1 Mb/s
and I got more speed read to gain more smooth performance to play game and more.
also speed up booting on your phone.
but decrease performace make a file like recording and take a photo.

Yes off course Increase If you boost your memory... more speed you have but low write.
I'm use ext4 partition too as my Internal memory with Internal HACK memory and OC.
