I have OCZ (3GB/s) Vertex 2's in several of our older Macs and I'm very happy with them. Anandtech has good reviews and comparisons of SSD drives. That's where I went when I was looking. SSD is so expensive, I'd tend to find the lowest priced one and then scour the web for its faults to make sure you aren't getting stuck with a unit that has some flaw like slow transfer rates. This is the biggest issue with SSD. Some have older controllers that don't support newer SATA speeds (6GB/s). Some have slow transfer rates even with the latest SATA.

In my main machine, I have a Seagate Momentus XT. It's a 7200 RPM 500 GB HDD / 4GB SSD "hybrid" and performs very well for only a 10% premium over a normal 7200 RPM drive versus the double or triple or even more you might wind up paying for an equivalent SSD.

 

15 or 13 use the same size SSD, 2.5, check out OWC

 

A 120GB isn't a good option if you need more space and have the money for a bigger drive.

If you need a 256GB drive and can afford it, then look at the 256's.
