Very odd indeed: 54 vs 8 minutes?!?
And the IO is still at around 33Mb per second. Let's

You're welcome. I still try to get a grid on local vs remote storage, HW RAID against SW, etc, etc. Just do not have the resources to get the hardware, but it would be a nice shoot-out: local vs remote (network), h/w vs s/w.
I think those NAS/SAN boys would be in for a surprise. I think CEO's would be in for a surprise; I think computing can be very cheap, using standard hardware, and just buy an extra spare.
No need for expensive "fast, reliable" SCSI - it is not faster, or more reliable. You seem to be proving it is not faster, Google has proven it is not more reliable than (S)ATA.
I'm from the old KISS school :)
