OCZ Agility Series

The OCZ Agility Series is an internal 2.5" SATA II Solid State hard drive that is available in 30GB, 60GB and 120GB capacities. This drive is similar to the Agility EX Series with the difference being this one comes in four different capacities whereas the EX only comes in 60GB, while the EX is an SLC (single-level cell) design as opposed to the cheaper and more common MLC (multi-level cell) found here.

A notable difference between SLC and MLC would be write speed, which is greater with SLC, although both are SSD and thus share similarly fast performance that is becoming more popular, especially with professional users and gamers. The ability to turn your computer on with almost no wait for the OS to load is a plus, as well as data intensive applications like video editing and rendering where fast data transfer to and from a storage device is crucial. Also there are no moving parts which extends the life of the drive to an estimated 1.5 million hours.
