I'm not a big fan of using hdparm for real benchmarking or comparing
things but for the sake of completeness.
/dev/sde:
Timing cached reads: 24004 MB in 2.00 seconds = 12025.18 MB/sec
Timing buffered disk reads: 982 MB in 3.00 seconds = 326.98 MB/sec
This is on a dual: Intel(R) Xeon(R) CPU E5645 @ 2.40GHz with
05:00.0 Serial Attached SCSI controller: LSI Logic / Symbios Logic
SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] (rev 02)
