I`ve got a pc with 2 harddrives setup in Raid0 (can`t give the model numbers atm cos a checking program is running).
The problem is that when u write to the array, it starts bursting @ 20-40 something m/s, then after a few seconds drops down to as low as 256kb/s - and stays there, perhaps fluctuating up to 1.5m/s.
Reading from it seems to be fine.
I`ve run the likes of HDTach, as it was one of the only things on the desktop, and the speeds it shows are in excess of 100m burst, averaging at something like 56m, short and long tests. I really expected it to give very low results, but it didn`t.
Could it be anything to do with strip size being not liked by the drivers ?
I`ve tried giving them power from other sources, just incase they lacked power from the system as a whole, but the same results occured.
EDIT: Also I`ve put 2 different harddrives in the same situation (different models) and they work great, average 20-30m/s.
