Hi,
The read speeds on my Pegasus 32 R8 are much slower than write speeds. (WRITE: 1407 MB/sec - READ: 506 MB/Sec). The R8 is formatted RAID 5, so that gives it a capacity of 98TB and I have roughly 20TB free. Also, I made sure to set the cache in the Logical Drive to ReadAhead/WriteBack in the Promise Utility but the read speeds are still much slower than the write speeds. Any ideas?

Hi Eric,
If there is any error with the drive it can cause a performance issue, did you get any alerts/events information for any drives recently?
It will easier for us to troubleshoot if we can have a case registered so please visit support.promise.com then create a web support ticket, attach a subsystem report to the case so we can investigate further.
No, I did not receive any get any alerts/events information for any drives recently. Ok, I'll set up a support ticket now. Thanks.

Did you ever find a solution to this? I also have the R8 in Raid 5 with no error messages and it was working at the expected write/read until recently the read dropped to around 550 MB/s.
Should note that I'm on Windows 10
