"Even though there is a plethora of mechanical hard drives on the market that support the SATA-600 interface, we really need a solid state drive to make use of the bandwidth available. Today we are going to compare five different models from Crucial, Intel, Mushkin, OCZ, and OWC to see how they perform.Recently, there has been a mass adoption of the SATA-600 interface by motherboard manufacturers thanks to native support in the latest chipsets from AMD and Intel. So if you're going to be building a new system anytime soon, it's likely that you'll be able to make use of the extra bandwidth of SATA-600 over the previous generation SATA-300 interface.Before continuing, we'd highly suggest that you read our Anatomy of SSD Units tutorial which provides all the background information you need to know about SSDs. The SSDs featured in this review use MLC memory chips.In the table below, we compare all the drives we're going to review. All five units use the standard 2.5" form factor
and the SATA-600 interface. The Vertex 3 unit from OCZ is available in two slightly different models. We have the MAX IOPS version for testing today.The advertised capacities of the drives on test vary slightly even though all of the drives on test feature the same number of memory chips. All five drives feature 256 GB of physical memory, but some of the manufacturers set aside a certain portion of the available memory for over-provisioning. This helps to improve the performance of the drive in the long run. The capacities of the five drives are displayed in the table below."
