In order to fully utilize SATA III you need a system with native SATA III support. P67, Z68, Z77 and X79 systems are preferred, but AMD has made advances in their newer SATA III systems as well. Older X58 systems with Marvell based SATA III ports do not deliver the same high levels of performance, so we recommend newer systems when available.
ATTO Baseline Performance
Version and / or Patch Used: 2.34
ATTO is used by many disk manufacturers to determine the read and write speeds that will be presented to customers.
What we really like about this drive is it doesn't ship with the TRIM killing firmware from SandForce. OCZ has their own naming system for firmware so we weren't sure if this was 3.3.2 or 3.3.4, but it was definitely not 5.0.1 or 5.0.2. What that means is you still have working TRIM and when OCZ's version of 5.0.3 comes out with working TRIM, you'll get a nice performance increase too. The 5 series firmware is around 10% to 15% faster than the older 3 series.
That said, the Vertex 3 480GB does take a performance hit when compared to the 240GB and even the 120GB. Can you really complain though about 540MB/s read speed and 460MB/s write speed? We didn't think so and even the most critical of performance have to admit that having 480GB of SSD capacity is means you can trade off some performance and still walk away with a big smile. This goes double for notebook users who don't have the space to install more than one SSD.
