Re: 10K Drives, Why not?

[Roberto José Etcheverry Romero <yggdrasil.raiker@xxxxxxxxx>]

Dr,
10k or 15k I think the problem there lies in the RAID code. Most
controllers from IBM i I've worked with have the same problem. If you are
initializing the LS BEFORE starting raid, it goes fast enough. After RAID?
slow as heck. Don't know why since it's just writing 0 to the disk. One of
the reasons I love external SAN, 0 writes are detected by the controller
and ignored...
Have you seen a big difference between 10k and 15k on this matter?
