In terms of hardware there is nothing new here, the combination of SandForce SF2281VB1-SDC controller coupled with 25NM Intel flash memory is the tried and tested solution of yesterday. This drive of course has the same characteristics we have already seen with this combination of hardware: relatively weak incompressible data throughputs, fantastic compressible data write speeds, average real world (424.5 MB/s) and average server workload performance (AS-SSD Total 836). The thing that is unique about this drive is its mSATA form factor which is approx one eighth of the size of a regular 2.5 inch drive. If you are looking for an mSATA SSD, this is one of your only and therefore best options. If you are not then there is far better performance and value for money offered by the newer generation of controllers. [Apr '13SSDrivePro]
The 250GB Samsung 850 Evo has a similar architecture to its hugely successful predecessor, the 840 Evo. Both drives are TLC based but the 850 uses 3D V-NAND as opposed to regular NAND. Both drives also feature a Turbowrite cache (TWC) which buffers up to 3GB of writes. The TWC enables high burst write speeds but when the cache exhausts write speeds drop to 300 MB/s. Comparing the 850 and 840 Evos shows that effective speed, has improved by 11% and the warranty has been extended from three to five years but prices are also up by 11%. The 850 Evo does put in superb benchmarks (second only to the 850 Pro) but these are only valid within the TWC. At current price levels the 850 Evo struggles to compete with the value leaders.
