The OCZ Vertex 4 is a fast SSD with a strong price/performance ratio. It also has 16GB more capacity than much of the competition. Unfortunately in our tests it was relatively slow when reading our collection of small files and folders. It also comes with only a three-year warranty. See all storage reviews.
OCZ Vertex 4 review
Although it's not quite as fast as its Vector sibling, OCZ's Vertex 4 is a very speedy SSD. It uses the company's older IndiLinx Everest 2 controller, but contains the same 25nm, IMTF (Intel Micron Flash Technologies), MLC NAND used in the Vector. The combination proved fast enough to perform well against rival SSDs in recent SSD reviews.
OCZ Vertex 4: performance results

OCZ's Vertex 4 is a very good value in the current SSD market.
The Vertex 4 wrote our 10GB file/folder mix at 411.3 MBps and read it back at 343.3 MBps. That second number was the slowest in the roundup—an odd hiccup for an otherwise very fast drive. The drive wrote our single large 10GB file at 599.3 MBps, and it read it back at 443.3MBps—the fourth- and seventh-fastest transfer rates, respectively, that we saw in those individual tests.
The 256GB Vertex 4's retail price is about £165, or about 64p per gigabyte, which is a very good price for a drive this fast. Only the Kingston HyperX 3K 240GB SSD and the SanDisk Extreme boasted lower street prices than that.
OCZ ships the Vertex 4 with a mounting bracket and screws, and if you look in the included manual, there's a serial number for Acronis True Image to aid in cloning your old drive.
The OCZ Vertex 4 currently sits at the sweet spot for SSDs: It's very fast and relatively affordable, and it has 16GB more capacity than most of its competitors.
