What about price to performance comparison?
(SATA) Micron MAX 5100 1.92TB is $1,179
(SAS) Toshiba HK4R 1.92 TB is $3,885
(SAS) Seagate 1200.2 1.92TB is $3,169
(SAS) Toshiba PX04SMB160 1.6TB is $3,675
I believe for a 1.92TB with very decent write endurance SSD, I would bet my regular/bursty workload data on it. The Intel SATA SSDs with 0.3x to 1x DPWD are complete garbage.
Additionally, comparing SAS with SATA SSD is definitely not a fair comparison.
