Testing methodology
We'll take a look at the OCZ Vertex 2E in relation to another SandForce-powered drive, this time in the form of the Corsair F80. What's more, we'll see how it compares to a couple of Force drives in RAID, a cheaper 64GB SSD from Crucial, and, finally, RAIDed and non-RAIDed mechanical drives from Samsung.Here's a more detailed look at our seven-way comparison:

Benchmarks |
|
|---|---|
| ATTO Disk Benchmark v2.46 | The freeware ATTO benchmark provides basic sequential speed results for both read and write operations. Using the default queue depth of four, we record read and write speeds during 1MB transfers. |
| CrystalDiskMark v3.0 beta 3 | CrystalDiskMark provides various storage benchmarks, but we're interested in the returned 32-thread 4K performance numbers to see how well the drives fare when tasked with numerous small transfers. |
| AS SSD v1.5.3x |
Another freeware benchmark, AS SSD is designed primarily for testing solid-state storage. We run the benchmark and record the drive's overall read and write scores. The final numbers take into account sequential speeds, input/output performance and access time. |
| Iometer v2008.06.18-RC2 | Iometer is an I/O subsystem measurement tool originally developed by Intel. To measure a drive's I/O performance, we set the benchmark to utilise 4KB transfers in a random spread. Read and write distribution is set to 50 per cent, and queue depth at 32. The test is run for two minutes and we record the total I/Os per second. |
| PCMark Vantage v1.0.2.0 | Emulating real-world use, PCMark Vantage spits out a bunch of data on the relative speed of the drives when undertaking common tasks. We record Windows startup, application load time and gaming performance. |
