The Plextor M5M is the most recent mSATA SSD I have looked at. It has both the same controller and NAND flash (albeit with fewer channels) as its regular SATA sibling, the excellent M5 Pro. The performance figures for the M5M lag the top nine SATA group leaders by around 30% on average. The weakest area of core performance is shallow queue 4K write speed which clocks in at 57 MBps on the M5M vs a group average of 118 MBps. In terms of server orientated performance, the M5M takes 13th place out of 29 with an AS SSD total score of 946. That said it's only fair to look at the M5M within the context of other mSATA SSDs. It's not a clear cut performance win between the M5M and the Intel 525 Series but the M5M is retailing for 23% less. Unless shallow queue random writes are a top priority for your use case the M5M is the clear value winner, and my top mSATA pick for 2013. ^{[Oct '13 SSDrivePro]}

The Evo is remarkable in that, like the Sandisk Extreme II, it features a second level cache. For the 250 GB Evo this consists of a 3 GB Turbowrite cache (TWC) which is a block of high speed Flash Memory. When the TWC is exhausted write speeds drop by approximately 50% but that won't often happen under typical consumer workloads. In terms of raw performance, even with its cache, the Evo still isn't the fastest drive. With a real world speed index reading of 439 MB/s the EVO is however, within reach of the two speed leaders (Vector and 850 Pro). At a price point of $130 the Evo is around 30% cheaper making it the best value for money SSDs I have seen in 2014. Comparing the Evo and the Sandisk Ultra Plus shows that the Evo is the winner but the Sandisk may be a viable alternative thanks to its cache-free, and therefore more consistent performance during extended writes. ^{[Aug '14 SSDrivePro]}
