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.

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.

Seagate Momentous Thin hard drives offer feature-rich, slim, lightweight style at price and capacity points that enable no-compromise designs for thin computing. Featuring the world’s first 7mm z-height (compared to a traditional laptop hard drive with a z-height of 9.5mm), 2.5-Inch form factor drive plus Seagate Smart Align technology, provides a transition to 4K sectors without the need for software utilities. Seagate’ has purpose-built the Momentous Thin hard drive to meet our customers’ demand for affordable, slimmer, fully functional computing solutions.

The Western Digital WD2500BHTZ is a high‑performance 250 GB internal hard disk drive from Western Digital’s legendary VelociRaptor family, engineered for users who need faster access and responsiveness than traditional 7200 RPM drives can provide. Unlike standard desktop HDDs, the VelociRaptor spins at a blistering 10 000 RPM and features a SATA III 6 Gb/s interface, allowing it to deliver sustained data throughput and quicker read/write access that benefits workstations, creative applications and performance‑oriented systems.
Whether installed in a desktop chassis or integrated into a high‑performance storage array, the delivers a notable combination of rotational speed, cache efficiency and sustained throughput that makes it a strong choice for applications where traditional HDDs fall short.
