Pros: Very fast drive. The first SSD I've used in a computer for myself. I use this in a corporate environment. The slowest part of my old computer was Outlook and searching Outlook. With this SSD, Outlook flies. I can sort by FROM and it responds instantly. I do video editing and accounting and a whole lot more and it makes all the difference. I'll never use rotary storage for my OS and software again. I've upgraded most of my users' computers with a Kingston V100+ 128GB drive and it is also very good. This drive, being SATA III and just plain rated faster is a noticeable difference between those two drives. I'm impressed.

Cons: After being up and running for 3 months, all of a sudden, Windows 7 froze and the hard drive activity LED was stuck on. I could get the computer to run normally for 20-60 minutes before it would do the same thing again. On reboot, the motherboard got stuck in a POST reboot loop. I blamed the motherboard for the freeze b/c the POST reboot loop happened with my HD removed. It had to be the mobo. I arranged for a new mobo and while I was waiting, I checked for updated firmware of my Plextor SSD. Plextor's website sucks. They don't give you previous version changelogs and it's hard to find and navigate. Anyway, I upgraded from 1.01 to 1.03 (on July 21, 2011) and got back to Windows. The problem was solved. If you get this drive, be sure to update the firmware to 1.03 (or newer) to prevent this activity. I'm not sure exactly what caused it (TRIM, maybe...it was mentioned in 1.03), but upgrading the firmware saved me. Didn't lose any data, either.
