Do these results look right for a RAID-10 consisting of 4x1TB Samsung F3 SATA drives connected via a Dell Precision T3500's integrated RAID controller (which I believe is an Intel-based "FakeRAID")?
I understand speeds will vary based on the controller, but I was surprised to see that the writes were consistently faster than the reads - which seemed counter-intuitive.
