Posted on by Daniel Kirstenpfad

This time we got a Hardware RAID0 Volume with 4 drives which made a volume size of 2431630530 sectors = 1187320 Megabyte.

Interface-Transferrate with a blocksize of 128 sectors at 0.0 percent of the capacity:

sequential read rate medium (unthrottled): 46290 Kilobyte/s
