Today we have a SSD that has been a recurring topic for SSD of the week this year. The Samsung 850 EVO was last covered when the 1TB capacity reached an amazing value of $0.33/GB. This week, however, we are focusing on value of the mid-size capacities along with the recently released 2TB capacity.
The Samsung 850 EVO comes in 120GB ($70.68), 250GB ($89.99), 500GB ($159.99), 1TB ($343.30), and 2TB ($706.51) capacities. Other variants of the 850 EVO are the M.2 and mSATA form factors. The 500GB costing $159.99 equates to it only costing $0.32/GB which is even more value than the 1TB previously costing $0.33/GB. On the flip side, if you need a large capacity in one SATA slot the 2TB isn’t far off at $0.35/GB.
The 850 EVO uses a dual-core MGX controller for the 120GB, 250GB, and 500GB capacities. Furthermore, Samsung used their 3-core MEX controller for the 1TB capacity and their new 3-core MHX SATA 3 controller for the 2TB due to the MEX controller not supporting more than 1TB of NAND Flash.
Using Samsung’s 32-layer TLC 3D V-NAND, the 850 EVO can reach sequential speeds of up to 540MB/s read and 520MB/s write across all capacities. Read IOPS for 4KB, QD1 performance is rated at 10,000 and write is rated for 40,000 IOPS. 4K queue depth 32 performance is rated for up to 98,000 IOPS read and 90,000 IOPS write. To achieve such numbers The 850 EVO uses Samsung’s TurboWrite technology which takes a small portion of the TLC 3D V-NAND and simulate it as SLC NAND to achieve faster performance. Along with TurboWrite another feature included is AES 256-bit Full Disk Encryption which is Windows eDrive compatible.

This Samsung SSD is really dominating the market with its price to performance ratio. Right now there are some really good deals on the mid-size capacities as well as the much larger capacity model. If you were questioning to get the 1TB when it was a steal before because you didn’t need a 1TB SSD, there is an even better price for the smaller capacities now, so think about it once more.
