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 Sandisk Extreme II uses the 88SS9187-BLD2 controller, Marvel's latest, and Sandisk's own 19MM MLC Memory. On paper this makes an extremely good combination and the benchmarks agree. The Extreme II scored an impressive 1143 in the server orientated AS SSD Benchmark putting it amongst the more capable server drives. In terms of real world consumer performance the Extreme II also fared well achieving a real world speed index score of 570.5 MB/s, amongst the top three scores we have seen to date. The Extreme II has everything going for it apart from its price which is currently significantly above average and hurting its value rating. Because the Extreme is the newest SSD we have in our group test we expect prices will drop with time. Until then, however, there is better value to be had elsewhere. ^{[Jun '13 SSDrivePro]}
