Samsung SSD 845DC EVO/PRO Performance Preview & Exploring IOPS Consistencyby Kristian Vättö on September 3, 2014 8:00 AM EST
|NAND||Samsung 19nm 128Gbit TLC|
|Sequential Read||Up to 530MB/s|
|Sequential Write||Up to 410MB/s|
|4KB Random Read||Up to 87K IOPS|
|4KB Random Write||Up to 15K IOPS|
|Endurance (DWPD)||0.3 DWPD (4KB Random) / 1.6 DWPD (64KB Sequential)|
The PM853T is the OEM version of the 845DC EVO and as you would expect, the two are very much alike. The difference between the 845DC EVO and PM853T is the firmware and the PM853T is geared more towards sustained workloads, which results in slightly higher random write speed (15K IOPS vs 14K IOPS) for the highest capacity. Endurance is also a bit lower (0.3 DWPD vs 0.35 DWPD) and warranty has dropped from five to three years, but otherwise the 845DC EVO and PM853T should be alike. Unfortunately I do not have the full data sheet, so all the specs are 'up to', but I will update the table when I receive the full specs.
