2TB 6G SAS 7.2K LFF (3.5 inch) DP MDL AW555A
2TB 3G SATA 7.2K LFF (3.5-inch) DP AW556A
I'm looking to populate the P2000 G3. The SAS drives are a little cheaper than the SATA drives in a bundle of six. Is there any reason why anyone would purchase the SATA drives over the SAS drives? Do the SAS drive offer any benefit other than 6G? Thank you.

SATA drives may be connected to SAS backplanes, but SAS drives may not be connected to SATA backplanes.
SAS interface is fully compatible with SATA interfaces, SATA drives can be used directly in the SAS environment, from the point of interface standard, SATA is a sub-standard SAS, the SAS controller can control SATA hard drive, but the SAS drives can not be used directly in the SATA environment, because the SATA controller can not control SAS drives.
Hope this may help you.
