Hi

I have three units connected to Intel NUC and 2 of them are performing very good. The other one for last 1-2 months is fast with reads (>100MB/s) but painfully slow with writes (2MB/s).
All units have 4 HDDs inside, all are configured with RAID5. All 3 units are the same - the same firmware etc and they are connected for over 1y to the unit.

I've swapped the cables between them, removed HDDs and them inserted them back... no help.

In Buffalo RAID Management Utility all units are fine - no HDD errors. On all of them cache on Windows level is enabled.
Any ideas what can be wrong with one of them?

Regards
Paul
