I had been reading a lot from this drive, I have a server with 6 of this drives, no issue yet, just wondering what is the read/write speed for this drives?
The manual just say 110MB.
I run this on Linux Centos 5.5 x64.
Running different benchmark tools I have this:
basic:
hdparm -Tt /dev/sdf && hdparm -Tt /dev/sdf && hdparm -Tt /dev/sdf
/dev/sdf:
Timing cached reads: 22752 MB in 1.99 seconds = 11426.02 MB/sec
Timing buffered disk reads: 344 MB in 3.02 seconds = 114.09 MB/sec
/dev/sdf:
Timing cached reads: 22752 MB in 1.99 seconds = 11424.32 MB/sec
Timing buffered disk reads: 352 MB in 3.01 seconds = 117.11 MB/sec
/dev/sdf:
Timing cached reads: 22736 MB in 1.99 seconds = 11416.38 MB/sec
Timing buffered disk reads: 352 MB in 3.01 seconds = 116.77 MB/sec

The server is running Xen kernel, this test are from the hypervisor with 2 cores dedicated and 1GB RAM dedicated to.
Do this numbers are in the normal performance?
What numbers do u have?
Thanks all for your time :smileyvery-happy:
