Just when you think solid state drives are about as fast as they are going to get, OCZ's Vertex 450
was released and proved us all wrong. As of lately SSD read and write speeds have pretty much capped due to hardware limitations of the SATA6 controller. Anywhere from 500-550MB/sec read/write speeds are about as fast as you are going to get. Manufacturers today are focusing heavily on the SSD's IOPS (Input/Output Operations Per Second). IOPS are used as a general benchmark for read and write performance so it's important to factor a SSD's IOPS in addition to it's read and write speeds when determining how "fast" an SSD really is.
The Vertex 450 is pushing some pretty strong ratings according to OCZ. Random read speeds peak at 85,000 IOPS, and random write at 90,000 IOPS. These numbers are very close to the Vertex 4 so it will be interesting to see how this newer generation compares to its predecessor.
As far as capacity goes, the Vertex 450 comes in three sizes: 128GB, 256GB and 512GB. Each come with OCZ's home brew NAND controller which based upon past reviews, has shown outstanding performance when compared to SandForce. The Vertex 450 uses the OCZ Indilinx Barefoot 3 M10 controller.

I mentioned on the previous page that the OCZ Vertex 450 is equipped with OCZ's own in-house controller, the
