Smart Array E200i performance on SATA, good, bad?

Hi,

We're looking at a stand-alone ESX server (ML350 G5) with E200i/128 BBWC with 4-6 3.5" SATA disks in a Raid-5.

Can anybody comment on the read and write performance of this setup? The disks will be moderately busy running 7 virtual machines. Anybody have any IOMETER read/write stats?

We don't want to enable the individual SATA hard drive caches, that's just silly.

Thanks,

Ben

It's looking like in this case I should not worry about the SATA drives and instead worry about the E200i. This guy upgraded to a P400/512 and performance increased quite a bit:

My only other experience with HP SATA is with the MSA20, not a stellar performer.
