B140i RAID5 write @ 80 MBs read @ 500 MBs

Just wanted to ask what peoples experience are with these base model ML30G9 with a B140i embedded controller using 4x MB001000GWFWK 1TB SATA drives in RAID5?

  • I have enabled/disabled write cache and it does not make any difference
  • I have enabled/disabled controller caching - no difference
  • Tried different drivers 62.6.0.64, 62.8.0.64 and 62.12.0.64

According to ATTO, the highest write is 80 MB/s (Megabytes p/s)  from 4MB although read is fantastic at 450 MBs+ at 4KB.

Any help would be much apprecaited.

I have logged a case and was advised it was write cache and waiting for further reply.
