Hey guys,
I'm buying another 36GB Raptor to have a play with RAID-0. I'll be using the drives as my OS and programs (not games though) drive and testing various stripe and cluster sizes.
My concern with other people's use of RAID 0 is that they set the stripe size too big to really benefit their system (ie 64kB when >90% of their files are <64kB) because they don't understand striping and/or go on what HDTach tells them (we all know HDTach likes big stripes ).
Can anyone think of any real-world benchmarks I could run? Windows boot time is one obviously...
My theory is that my stripe size should be ~ (median file size on the drive/the stripe width) (ie 2 for two drives in RAID 0) and that the cluster size should be ~ (stripe size/2).
I expect when I set the cluster size too small, CPU usage and / or access time will become an issue, offsetting the increased throughput.
And before anyone jumps on the old 'RAID 0 doubles your chances of data loss' - it's cool, because it will be on my gaming rig and I use Ghost images for my OS. If the RAID volume gets screwed for whatever reason, it's no biggie.
