OCZ has shown that the venerable Vertex line still has some life left in it after all despite the Vector taking the performance crown earlier this year. As we mentioned in the intro, the key difference between this drive and the original is the move to smaller 20nm NAND modules. While this does impact performance slightly, it's not really enough to worry about. In fact, you'd be hard pressed to find any differences between this drive and the original in daily use.
What you will notice, and what OCZ has noticed, is a lower overall manufacturing cost - savings that are passed on to the consumer. As of writing, the 120GB Vertex 3.20 retails for $129.99 while the 240GB unit can be had for around $235.99 at various online retailers - or about $15-30 cheaper than comparable Vector drives. Whether or not the added performance and extra two years of warranty coverage (five years total on the Vector) is worth it will be for you to device.
Perhaps the only knock I can find on this drive is that it still includes the older SandForce SF-2281 stepping chip instead of the newer B02 revision. The newer revision would have been nice for mobile applications as it sips less power which means, longer battery life from your notebook.
That said, the Vertex 3.20 is still a great solid state drive for anyone looking to boost the performance of their desktop or notebook. As I've been saying for years, moving from a traditional spinning hard drive to a solid state drive is the single best overall performance upgrade you can do for a computer.
