Testing:

Testing the OCZ Vertex 4 256GB solid state drive will consist of running it through multiple suites of tests...

» CrystalDiskMark 3.0.1 x64
» HD Tune Pro 5.0
» ATTO Disk Benchmark v2.47
» AS SSD Benchmark 1.6.4237.30508
» PassMark Performance Test 7.0

For comparison purposes, the OCZ Vertex 4 drive will be matched up against the following drives:

» Kingston 128GB SSDNow
» OCZ Agility 3 120GB SSD
» Patriot Inferno 60GB SSD
» Intel 520 series 180GB SSD
» Seagate 7200.12 SATA III hard drive.

CrystalDiskMark 3.0.1 x64:

CrystalDiskMark is capable of testing sequential and random data transfer speeds for drives. All tests in CrystalDiskMark were conducted using 1000MB test files; the average of 3 test runs is presented in the charts below. In these tests, the higher the score the better the performance.
