Add up to 250GB of storage capacity to an ultra-slim notebook or compact desktop computer with the MX500 M.2 Internal SSD from Crucial. This solid-state drive features an M.2 2280 form factor and is equipped with a SATA III interface, Silicon Motion SM2258 controller, and Micron 3D TLC NAND Flash technology to deliver up to 560 MB/s sequential reads and 510 MB/s sequential writes. For securing sensitive data, AES-256 encryption and Opal 2.0 are available. Additionally, included along with the drive are mounting screws as well as Acronis True Image software, which provides an easy-to-use backup solution.

Quiet – In a notebook drive, silence is golden. WD’s exclusive WhisperDrive™ combines state-of-the-art seeking algorithms to yield one of the quietest 2.5-inch hard drives on the market. These algorithms also optimize the way a drive seeks for data, which significantly improves power consumption. So now silence (and longer battery life) is golden.
Reliable and Rugged – WD’s ShockGuard™ technology protects the drive mechanics and platter surfaces from shocks. WD’s SecurePark ™ parks the recording heads off the disk surface during spin up, spin down and when the drive is off. This ensures the recording head never touches the disk surface resulting in improved long term reliability due to less head wear, and improved non-operational shock tolerance.
The Toshiba AL13SE series of 2.5-inch 6 Gb/s SAS interface hard disk drives offer enterprise-class performance in capacities ranging from 900GB to 300GB.
The AL13SE is the first 10,000 RPM class model enterprise drive from Toshiba to achieve 900GB capacity and is also the first of Toshiba’s 10,000 RPM drives to employ a dual- stage head positioning actuator that provides additional performance gains, including a 32% increase in sustained transfer rate.

The range of scores (95th – 5th percentile) for the WD Blue 2.5″ 500GB is 38.4%. This is a relatively wide range which indicates that the WD Blue 2.5″ 500GB performs inconsistently under varying real world conditions.
