Enterprise SAS SSD vs Consumer SSD

 The time was allocated to do a quick test to compare consumer grade SATA SSD drives to Enterprise grad SAS drives.   The SAS drives are 12Gbps, the SAS card is also 12Gbps.  The tests were done on the same Windows 10 desktop with the same LSI SAS card, expect where noted a PowerEdge r730 was used.

Impressive results!  12gb SAS SSD drives are very near NVMe performance, and nearly double that of the SATA drives.  Is the performance due to having more cache?  Or is it because the SAS drives are 12Gbps vs 6Gbps on the SATA drives?  It should be noted that during testing the SAS drives consume roughly 2 more watts at idle 5 more watts during the test.   The SAS drives were also MUCH warmer to touch where the SAS drives were ambient temperature.
