The Plextor M3 looks exactly the same as the previous model the M2. The new drive also supports SATA 3 but it's now a lot more affordable, costing just around $1.40 per gigabyte, compared with the $1.80 of the previous model.
The Good
The Bad
The Bottom Line
The only explanation for this is that it's also now slightly slower than the M2 in my testing, though still very fast, performing on par with many other recent SATA 3-based SSDs. That said, it offers a great boost to any computer that moving to a SSD from a regular hard drive.
If you have a computer that's using a hard drive as the boot drive, the Plextor M3 makes a good replacement.
