Cost per gigabyte
SSD prices have been going down since the beginning of the year and the Vertex 4's pricing reflects this trend. The new drive comes in 512GB, 256GB, and 128GB capacities that carry an MSRP of $649, $349, and $179, respectively, making the cost per gigabyte around $1.30 to $1.40, quite affordable. Street prices should be even lower.
SSDs are still much more expensive than regular hard drive and hybrid drives; for example, the Seagate Momentus XT hybrid drive costs just $245 for 750GB, or 33 cents per gigabyte. Hopefully SSD street prices will drop even lower and soon we'll see SSDs that cost just $1 per gigabyte or even less.
The new OCZ Vertex 4 offers much better performance than the OCZ Octane, which uses the earlier generation of the same controller. I tested both the 256GB and 512GB versions of the Vertex 4 and, as stated by OCZ, the 512GB version was faster than its lower-capacity brother. Unlike hard drives, for SSDs larger capacity generally also means better performance, especially in terms of life span.
When used as a secondary drive, the 512GB Vertex 4 offered an average speed of 247MBps, putting it among the top three on the chart. The 256GB version, on the other hand, offered just 190MBps.
When used as the main boot drive of the test computer, the 512GB version scored about 168MBps, in the top two on the chart, just behind the Samsung 830 Series. The 256MB version scored lower at 148MBps.
The two versions, however, gave identical boot and shutdown times, at 12 seconds boot and 7 seconds shutdown. These times are about as quick as it gets. They also both offered virtually the same overall performance in my testing. It's very hard to quantify this improvement but all applications I tried on the test computer with the Vertex 4 installed, especially heavy games, loaded very quickly, much more so than when a hard drive was used. It's the kind of improvement where once you have it, you'll never want to go back.
Despite the minor differences between different capacities mentioned above, it's safe to say that the Vertex 4 will offer the same great experience, no matter what capacity you get.

Service and support
OCZ backs the Vertex 4 with a five-year warranty, which is two years longer than it gives the Vertex 3. This shows the company's confident in its new controller. When it comes to storage devices, the length of the warranty is the most important factor and OCZ delivers that for the Vertex 4.
With great performance, friendly pricing, and included accessories, the OCZ Vertex 4 makes an excellent replacement drive for any computer.
