Ideal stripe size for SSD RAID 0 running OS and apps?

[Sunayknits]

Dual SSD RAID 0 set-up running OS and apps. I assume the smallest stripe that you can get is optimal with SSD. Does anyone disagree?

I just installed 3x Samsung SSD RAID 0 w/onboard nVidia controller and I'm wondering the same thing.

IIRC, SSD has more trouble with small writes. I would guess that a medium (64Kb or 128Kb) to large (256 or 512) stripe size would be optimal, perhaps even greater.

The problem of course is that this whole system was designed to overcome mechanical hard drive limitations, and in our case all it does is increase available bandwidth. Basically we're just muxing a bunch of memory on a SATA controller instead of the system board.

I think very soon we will see a paradigm shift in the way that data is stored. The whole concept of a 'disk' now seems a bit more vague and unnecessary with available memory that's soon going to approach DRAM speeds ...

Just thinking out loud

I was going to do some quick tests tonight but man that crap takes so much time ...
