OCZ Vertex 3 Pro SandForce SF-2000 Based SSD Preview
Test Setup and IOMeter 1.1 RC
Our Test Methodologies: Under each test condition, the Solid State Drives tested here were installed as secondary volumes in our testbed, with a standard spinning hard disk for the OS and benchmark installations. The SSDs were left blank without partitions wherever possible, unless a test required them to be partitioned and formatted, as was the case with our ATTO, Vantage, and CrystalDiskMark benchmark tests. Windows firewall, automatic updates and screen savers were all disabled before testing. In all test runs, we rebooted the system and waited several minutes for drive activity to settle before invoking a test.

As we've noted in previous SSD articles, though IOMeter is clearly a well-respected industry standard drive benchmark, we're not completely comfortable with it for testing SSDs. The fact of the matter is, though our actual results with IOMeter appear to scale properly, it is debatable whether or not certain access patterns, as they are presented to and measured on an SSD, actually provide a valid example of real-world performance for the average end user. That said, we do think IOMeter is a gauge for relative available bandwidth with a given storage solution. In addition there are certain higher-end workloads you can place on a drive with IOMeter, that you really can't with most other benchmark tools available currently.
In the following tables, we're showing two sets of access patterns; our
Workstation pattern, with an 8K transfer size, 80% reads (20%
writes) and 80% random (20% sequential) access and IOMeter's default
access pattern of 2K transfers, 67% reads (34% writes) and 100% random
access.
The upcoming OCZ Vertex 3 Pro significantly outperforms every other drive according to our IOMeter tests. Using both our custom Workstation access partern and IOMeter's default pattern, the Vertex 3 Pro offers the most IOps, the fastest transfer rate, and the quickest average response time.
