840 EVO

Samsung introduces yet another solid state drive in the 840 family with the 840 EVO. This Client PC SSD is capable of reaching a Samsung-840-EVO-SSDmaximum sequential read speed of 540 MB/s and a maximum sequential write speed of 520 MB/s (except for the 120 GB model which only reaches a maximum write speed of 410 MB/s). IOPS numbers for 4k random read and write are listed as 10,000 and 33,000 respectively. Users can choose between 120 GB, 250 GB, 500 GB, 750 GB and 1 TB capacities.

As expected, Samsung utilized their proprietary 3-core MEX controller and Toogle DDR 2.0 NAND on the 840 EVO. Among its features are TRIM support, Garbage Collection, S.M.A.R.T., and AES 256-bit encryption. The 840 EVO comes with a limited three-year warranty and a Mean Time Between Failure of 1.5 million hours.

To say that I really like the EVO is an understatement. If Samsung can keep quantities of the 840 EVO flowing, and keep prices at or below its MSRP, it’ll be a real winner and probably my pick for best mainstream SSD.


Quick and dependable yet roomy and affordable — everything we’ve been waiting for in an enthusiast solid state drive.


This is definitely the most complete package released to date yet.
