OCZ Vertex 120GB SSD

Test Setup

Testing hard disks can be difficult, especially when using such a hard disk intensive operative system as Windows Vista 64-bit - give it thirty seconds and it's spun your hard drives up to handily defragment or index them - not exactly what you want when trying to ascertain a hard drive's peak performance.

To get a decent idea of drive performance in a variety of real world circumstances we tested using a variety of tools. HDTach 3.040 gives us a good idea of theoretical drive performance, FC-Test’s intensive file transfer abilities give us a good idea of real world drive performance, and our image editing suite should expose any problems in the disk controller being unable to keep up with read/write instructions - something cheaper SSDs are prone to.

We've also chosen to now include random read and write performance figures following requests from our forum members. Older SSDs have suffered particularly badly in random write latency department, leading to the infamous "stuttering," hard disk effect as the hard drives lags. While we've been unable to retest every drive and SSD that's been on our test benches in the last nine months, we've made an effort to include the major players and more popular drives.

Finally, we test hard disks in genuine real world circumstances, cloning an install of Windows Vista Home Premium 64-bit onto the drive and then timing the resulting clean boot time before also timing Crysis level load times.

In order to maintain good benchmarking practice, each test was performed five times with the highest and lowest scores discarded and the remaining three results averaged.
