SATA-II 3 Gb/s RAID Performance Guide

[TechZ]

- HardCoreWare has posted a SATA-II 3 Gb/s RAID Performance Guide.

[confus-ed]

Thanks Techz .. an interesting read with a hole load of benchmarks which if I were foolish enough to show to someone in the market for a low end server using sata instead of SCSI might lead to me killing them as they fail to grasp what sustained transfer means ..

Stuff like this

This is the ONE test that is going to show a 3 Gb/s transfer rate at its very best. Here you can see that a single 3.0 Gb/s drive performs at the level of two 1.5 GB/s drives in RAID 0. And check out that burst rate for 3.0 Gb/s RAID 0! We're approaching SCSI 320 burst levels here, with a pair of $100 drives.

is just entirely misleading - even if you follow up with this

Of course, that is just burst speed, and it's definitely not something to get too excited about. If you're the type who likes to brag about benchmarks though, this is the one to use.

(he forgets though to add the phrase 'so you can look a complete tit when talking to anyone who actually understands this stuff !' )
