Thanks Jack, understood.  Don't know if anyone has tried it on the HP3K yet.  Wouldn't even know if they could be configured.

I added the last question only because I read in one top google searches the following quote:

"SAS/SATA stacks, being designed for disks with millisecond latency, aren't optimized for the 50-microsecond latency of flash and are adding latency themselves."
