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.

In today's market the only thing the Mushkin Chronos has going for it is the fact that it is an SSD and as such considerably faster than a regular hard drive. Compared to other SSDs this drive is right at the bottom of the pack. Thanks to the combination of its now aged Sandforce controller and the use of Asynchronous Flash Memory, the Chronos has a real world speed of just 224 MBps. Its AS SSD total score of 487 is also the worst I have seen to date on a 240 GB SSD. To be fair this drive is over two years old which equates to around four generations in the very fast moving SSD space. There are far better value for money alternatives available.
