It depends on your application, hard drives used, and computer system. You can try to start with 16 kilobyte block per hard drive or 64 kilobyte block total.

You forgot XFS in your filesystem list. I rather use XFS instead of other filesystems that you mention. IMHO, ReiserFS and Reiser4 are experimental.

ive read that 64k is ideal for windows..

with the 4-way raid, im getting 100MB/s in HDTach witha tripe size of 512KB (which seems a little low)

my current plan is to use 2 of the drives with a stripe size of 64k with windows and the other two with linux.. im a general desktop user, bit of divx encoding and lots of compiling. Im using the AMD FX-55 with 2GB of RAM

so what would be an ideal linux stripe size?

is XFS well supported..? do all apps run well in XFS without problems?(especially Cedega,Crossover,vmware..im looking to do away with windows forever)..ive read that XFS is faster but the general public doesnt seem to use it too much...why?

XFS is well supported. It fixes it self faster than any filesystem if it is corrupted. The reason why XFS is not used by others is because most Linux distributors do not enable it in the kernel. XFS does make the kernel a little bigger, so it is a little hard to put it on a floppy. To get good performance with XFS, you need a minimal of 256 MB of RAM.

I have used XFS with WINE, VMware, Unreal Tournament, and many others with out any problems. I do not have any problems with VMware virtual disk image when using one big file without the need to split it in 2 GB files.

Use GRUB as your bootloader because LILO has problems with XFS. For video recording and better read/write performance I suggest keeping the block size of the XFS filesystem low.

Again you have to find out your self that will give you a good balance between read and write performance. Every system is different.

BTW, use Xvid instead of DivX. With Xvid you can make it DivX compatible.
