James,
you are almost right, you have it right about SATA being optimized
for linear access speed, but you missed the point when you thought that
they are just as good as SCSI or that the major difference is marketing.
"optimised for linear access speed", when translated into english, means
"no optimisation, cheap electronics". SATA is really ATA with smaller
number of wires. This is not buying you anything in the server
environment. The request queing leading to sustained throughput on random
requests is the real advantage of SCSI over ATA / SATA. julius
