NAS 542 SATA speed

[Heribert]

Hi,

I have a NAS-542. The first three disks work at 3 Gbps, but the fourth works at 1.5 Gbps.
Is it normal? Or is my NAS defective?

If I plug in only one disk into different slots, the result is the same - The same disk works at 3 Gbps in slot 1..3, and at 1.5 Gbps in slot 4.


Sometimes the disk4 is mounted half an our after the NAS is powered on, so the RAID must be resynced. Have you seen a similar problem?


Thanks in advance
