Plextor PX-128M2S review

Can this second generation SSD drive hold its own in a crowded market?

TODO alt text

To test SSDs in as close to a real life scenario as possible, we install them as a boot drive and install a full operating system, in this case the Windows 7 Ultimate 64-bit. We test in this clean state, fill the drive up with data, then delete it, running through this cycle a few times before testing the drive again to see if there was much difference in the results after subjecting the drive to this usage cycle.
