bump post, but i'm looking to find some sort of CCTL (TLER) utility for this here hitachi raid. running ich10r and matrix. somebody inquired as to whether or not i could mess with it and now i'd like to know myself.
From the platter density, it's clear that they hold 330GB at most, so I wouldn't choose a 500GB disk unless I'm sure it has 3 heads, not 4.
The random access measurement on the first 200GB can only be compared with 200GB on another disk or group. And anyway, as Hd Tach asks for a single sector, this figure is meaningless for a Raid. Raid increases access times for files split across several disks, making 7200rpm Raid slower than a single disk for OS and applications loading.
But then, their measurement by HdTach and HdTune tells 19ms random access! Max stroke and minimum delay are just as bad. They probably had the AAM on, but then, was it active during CrystalDiskMark measures as well?
