SteveRo,

Sorry about that, the default size is 1GB, 4x the size of the controller cache should be fine.

The cache run was impressive, especially at low QD's, it did flatten out quite early compared to my LSI 9260 but then again the LSI is more like your last run at lower QD's.
(I've never tried a run using only cache on the LSI so I'm tempted to try)

It looks like xs somehow is nesting the zip files, strange one.

I nearly ordrered an Areca 12xx when I looked at your first results file
The Areca 1880 series is still a few months ahead, must resist.
