Formating SD Card - General Topics

What are the best parameters to use? What is the optimal cluster size?
Will the cluster size affect performance ?
I have 1 GB new SD Card.

Look at my report...

Does SD card slow the speed of wm6

when i flash my wm6 at first its good.but when i reset wm6.it goes slow.do u guys have any idea.mine is g3.thank u very much
I think it depends on what is loaded in your startup folder. But the SD Card will reduce your Program memory a little, I’ve seen up to a few MB. There is a reg edit you can do to increase the speed the wizard access the SD Card.
hklm\drivers\sdcard\clientdrivers\class\mmc_class
hklm\drivers\sdcard\clientdrivers\class\SDMemory_class
And change value of BlockTransferSize from 64 to 128 or 256.
I don't know if it will help or if you will see a performance increase.

Peak Performance from Sd card.

I want to have maximum performance from my mini sd card.I heard that formatting it in an appropriate way would increase its performance.By performance i literally mean that the transfer rates are increased.Like when i am moving some big songs and transferring big fies via pc.
I had a magician before and it would take less time to copy a 650mb file than my hermes,
So any body tell me can i do anything to get higher transfer rates?
I mean fat ot fat32? And the allocation unit size?
I dont care if i have to sacrifice my space for performance
Have you found out anything about how to format your card or if there are any new drivers for better performance?
I'm on a Blackstone.
the program pocketmechanics let you benchmark sd cards and compare the result with other cards

Why we should divide sd card two part(fat32 and ext 4)?

I will install cyanogenmod[02.14.2012]. Before installing that, must i divide the sdcard two part(ext4 and fat32)?
if i don't divide sd card ,can i install app to sd card(can i experience any problem app moving sd card)?
Well, you hould divide sd card for three parts, not two.
fat32, ext4, swap.
Why ? Because phone with swap works much more faster.
how many megabytes are enough for swap and ext4?
and can we divide using MiniTool Partition Wizard Home Edition 7.0 ?

There is a rule that swap must be two times the size of your physical memory (RAM), so you should set it to 512MB of swap. That's how you have 768MB of virtual memory. The tricky party is that with swap your phone becomes able to run heavier apps which requires more RAM but also since you use SD card instead of ram your phone becomes slower when it's in use of swap.
As for the ext4 partition, I usually set it to ~400MB. But I never manage to even come closer to use all of those 400MB. 50+ apps are arouond 200MB so decision is yours.
Cheers!
additon, how can divide sd card? i used minitool partition home edition.will be this cause any problem?

No problem but it's better to use a memory card reader than to make it with phone in usb.
I tried with phone in usb and I had to pull battery and to retry.

With all new ROMs (CM7 by fjf, Cronos Ginger 1.7, etc) coming in to our phone, are all of them support this swap partition? Thanks.

[Q] Best cluster size for 8GB SD card?

Hi, I have a 8GB SD card that is formatted in a smartphone and has cluster size of 32 KB. Isn't this too big, shouldn't it be 4 KB? Can this increased cluster size increase the NAND FLASH write amplification and wear the card prematurely?
I am using it in a PC all the time, not in a smartphone any more.
P.S. I have a lot of software installed on this card and changing the cluster size would be tedious...

Apps installed on SD

Many people want to move their apps to SD because of the space issue.
I am a minimal app user
What I concerned is performance or speed.
Will the performance increases if I move an app to the internal SD card?
Some say that the phone will run faster because less phone space is used.
Another question is the internal SD card really an SD card?

No... I don't think there will be any change... Just saves a little space...
And internal sd card is not an sd card like external sd card i.e. memory card... It is like a memory card placed on phones motherboard... Maybe It includes system partition and other partitions... You can't remove it or change it yourself...
