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 250GB Crucial BX100 SSD is the value orientated variant of Crucial's M range of SSDs. The BX100 uses the same NAND as its premium MX200 sibling but the BX100 uses a Silicon Motion controller as opposed to the Marvel controller found in the MX range. Feature wise the BX100 is missing SLC caching and there is no hardware encryption (so security frameworks such as windows Bitlocker will operate less efficiently). In terms of I/O performance the BX100 looks promising. Comparing the BX100 and MX100 shows that the newer BX100 may be faster than its predecessor but as yet there are insufficient user benchmarks to draw any definitive conclusions. The BX100 has only just started hitting the shelves so there's plenty of room for price reductions from its already reasonable price tag. I will revisit this review when I have more performance data for the BX100. ^{[Jan '15 SSDrivePro]}
