| - | As an example, one of our VPOP3 hosted service servers was running with a RAID 10 array on SATA drives, with no BBWC. This hit performance issues, the IOPS was around 170 IOPS, and the Avg Disk Queue was regularly over 3 or 4 for long periods of time. We moved this to a new server with a RAID 10 array on 15000 SAS drives with a BBWC, the IOPS has increased slightly to 230 IOPS, but the Avg Disk Queue is now about 0.2, and the performance is much greater. | + | As an example, one of our VPOP3 hosted service servers was running with a RAID 10 array on SATA drives, with no BBWC.
