Samsung SSD 840 EVO Series 750GB Solid State Drive

**~*77*~**

Samsung has knocked another one out of the park with its new 840 EVO Series SSD. Designed and built entirely in-house, this ultra-slim, high-capacity drive combines Samsung's triple-core MEX controller with their second generation 3-bit MLC NAND flash. Add in a massive DRAM cache and Samsung's new TurboWrite technology and you have a drive capable of some pretty impressive performance. In our sequential read and write tests, the 750GB version of the SSD 840 EVO was able to read at speeds as high as 560 MB/s and write at speeds in excess of 490 MB/s. The drive also did very well in our random write tests, producing more than 85,000 IOPS at low queue depths. While a big improvement over the SSD 840, these numbers aren't as high as what we saw with the SSD 840 Pro. However, with RAPID mode enabled, the performance can be boosted beyond what a single, SATA SSD is normally capable of. cdrlabs.com
