The 128GB Plextor PX-128M2S offers modest capacity and modest performance at a modest price (for a solid-state drive, anyway).

Still, the 128GB Plextor PX-128M2S has everything else it needs to be a useful, and relatively affordable, addition to a PC.

Reviews Word on the street for the Plextor PX-128M2S


7.0
Because of the way SSDs operate, comparing speeds across capacities is seldom useful; higher-capacity drives are almost invariably also going to be faster (at least up to a point).

What People Are Saying Give it to me straight

Performance

But to give you an idea of the PX-128M2S's capabilities, it turned out sequential read and write times of 361.3MBps and 179.5MBps respectively in the AS SSD Benchmark; the slowest 250GB-class SSD we've seen, the 256GB Crucial m4, earned 418.5MBps and 222.75 on the same tests.
by PCMag (Jun, 2011)

Capacity

The Plextor PX-128M2S has a 128GB capacity and costs $279.99 (list), much less than you'd pay for a higher-capacity drive like the Crucial m4 ($499.99 list, 3.5 stars), the Intel SSD 510 Series ($584 list, 4 stars), or our Editors' Choice OCZ Vertex 3 ($499.99 list, 4.5 stars).
