thanks for the reply.

Okay, I guessed so, but I wasn't sure. Thanks.

Normally not. But unfortunately, I am on dedicated storage with a
superfast Adaptec 5085 RAID controller. It has a disadvantage: When
using RAID 6 (which is very fast on this hardware) it has only enough
segments for 4 logical drives. And 4 times 2 TB are too less :(
