Reading an ATTO score?

Hmmmmm...

Well I don't know what to make of this, except that my array shows negligible performance differences in any configuration. I was hoping to get a second or third opinion on that.

VIA 8237 SATA RAID 0
Disk 0: WDC1600JB w/ SilImage PATA->SATA adapter
Disk 1: WDC1600JB w/ SilImage PATA->SATA adapter

First number in title is stripe size, second is block size.

Test methodology:
Install Win2k professional on WDC2500PB hard disk on PATA Primary Master. Install all drivers, windows updates, and patches. No VIA latency patch since VIA lists the 8237 southbridge as incompatible with the latency patch, and it shouldn't be needed since the RAID controller isn't on the PCI bus.

Use VIA Raid Tool to create RAID0 with 16KB stripes. Reboot
Create primary NTFS partition on new disk array.
Format partition with 4KB allocation units in Windows Disk Management interface.
Benchmark with ATTO Disk Benchmark.
Format partition with 8KB allocation units in Windows Disk Management interface.
Benchmark with ATTO Disk Benchmark.
repeat and increment allocation unit size up to 64KB.
Delete RAID array in VIA RAID tools.
Create new RAID array in VIA RAID tools using 32KB stripes.
Reboot.
Repeat above for 32KB stripes.

Anything I'm missing? I didn't use quick format, but the array never took more than a minute tops to format for some reason.

Ok, looks like 16K stripe and 4K block is a winner for this array. Highest all-around read and write scores.
