I currently have 2x74 gig raptor's in raid0 @ 16k block size, in the past i had always used 64k for my raid0 but a friend told me that i should use 16k size for my gaming rig, what is the best block size for a gaming rig? i mean this pc is straight gaming, nothing else.
Smaller files do not really need to be split, since it can slap them on disk so fast anyway. I am using 64k on my 2 74gig Raptors. I get 110MB sustained transfers and 7.5ms avg seek times.
In games the benifit is mainly on boot times, and large blocks are loaded, during gameplay, RAID does not help much anyway.
2 years ago I used 16k on my Abit AthlonXP board, and it actually hurt transfer speed compared to 64k.
