OCZ Vertex 4 256GB Solid State Drive

Performance Test Platform

The hardware chosen was picked to reflect that of a relatively modern computer system that an enthusiast may own.  Thanks goes out to our sponsors who have allowed us to keep some of our review sample parts, which in turn are being used for our SSD test bed (as indicated by *).  The configuration of our SSD testing system is as follows:

  • Intel Core i7 2700k @ 4.5GHz
  • ASRock Z68 Extreme3 motherboard
  • G.Skill Sniper 2x4GB DDR3-1600 memory kit

A base Windows 7 Professional 64-bit install is used for the operating system.  Non-essential services including Fax, Firewall, System Restore, Windows Defender, Windows Search, Windows Update were disabled, as they can affect testing results.

All tests were performed 5 times each, and the average of all test runs were used as the results.  Between each test run, each SSD had the ATA Secure Erase command executed on it using Parted Magic to restore performance.

The SSDs were connected to the SATA 6G connectors on the test bed's Z68 based motherboard.  Intel's Rapid Storage Technology AHCI driver was used.
