HP SATA SSD vs SAS HDD

Hi All,

I just got a HP DL380Gen9 server with 2x SATA SSD 120GB (D drive), and 2x SAS 300GB HDD (C drive) . Both raid 1.

SSD: HP 120GB 6G SATA VE 2.5in SC EV G1 SSD

SAS HDD: HP 300GB 6G SAS 15K 2.5in SC ENT HDD

Installed Windows 2008 R2 Enterprise through intelligent provionsing tools. (hope all drivers are updated).

Just run some HDD benchmark tools. And found that SAS HDD is faster than SSD HDD....... Attached the results....

Any suggest about the odd result? Or this is the fact?

Thanks.
