RAID strip size : 64K or 256K?

[fiza]

Just configuring our new HP Gen 9 server and want to use RAID 10 for the data drives. When im in the config utility for the controller and I choose RAID 1+0 it defaults to 256KiB as the strip size. Should I leave it as 256 or change it to 64KiB? The server is going to be our main file server.

 

what do you think?

I did a whole load of experimentation with this a while back by creating various level RAID arrays with varying stripe sizes and benchmarking them all. I eventually came to the conclusion that a 64kb stripe was the best to use as it seemed to be the best compromise between throughput and simultaneous operations.

Was 64kb still the best at RAID 10?

Yes, it was
