Quick stripe-size question...

Recommended Posts

Apologies if this has been asked before, but I've just got a quick query about choosing stripe-sizes for my RAID-array. I'll putting together a RAID5 array with the following drives:

4x 160GB, 2x 320GB

I'll be doing it by creating two 320GB RAID0 arrays from the 160s, and then creating a 4-drive RAID5 array from these two arrays plus the 320GB drives. Now intuitively it seems to me like it would be a good idea to choose the stripe-size for the RAID0 array to be half the stripe-size of the RAID5 array? So that a chunk of the RAID5 array splits up into exactly one chunk for each drive in the RAID0 array.

Is this correct? Also, what stripe-size would be good for a fileserver which will just be used for storing files, and streaming audio/video over a LAN (so STR is what I'd like to optimise). I was thinking 32KB for the RAID0 arrays, and 64KB for the RAID5 array?
