Do NOT format your Vertex 2 before using it.
1) Enable AHCI.
2) Attach it as a secondary drive and use the
OCZ Toolbox to update the firmware and then secure erase it.
3) Remove all other drives and install Windows 7. Tell it to install to the raw unpartitioned space, do NOT create a partition or format manually.
4) Install Intel RST 9 series drivers or AMD drivers and restart.
5) Do an ATTO benchmark and Windows Experience Index. Don't unnecessarily do more benchmarks than you need cos it will reduce performance.
6) Re-attach your other drives and away you go. Leave the PC on but logged off for a few hours a week to ensure the garbage collection is given enough time to keep the drive at full speed.
