Toshiba has added 12.0 Gbit/s SAS interface 512 native and Advanced Format models to its 15,000 RPM Enterprise Performance Class HDD model line. These newest additions are designed for mission-critical workloads, delivering the benefits of 12.0 Gbit/s SAS host transfer rate and enhanced power management features for integration with rack-optimized data centers. Toshiba says applications such as OLTP and databases will see improved performance from faster host transfer rates using 12.0 Gbit/s SAS controllers. Also, new AL13SX series models supporting 4K native sector technology may further improve application performance in supported environments.

The AL13SX series is available in capacities up to 600GB in a 2.5-inch form-factor. The 600GB is a 100 percent capacity increase over the company's prior generation 2.5-inch models and provides faster seek performance and a lower power profile compared to legacy 3.5-inch 600GB models. Models supporting 512 native sector length technology provide compatibility with industry-standard applications and operating environments. The 512n models offer industry migration to higher performing, more power and space efficient 2.5-inch form factor (when used with appropriate form-factor conversion hardware). Additional models supporting 4Kn or 512e Advanced Format sector lengths provide effective performance and data integrity for environments that support these sector technologies.

In addition, Advanced Format models offer Toshiba persistent write cache technology for improved data integrity in un-aligned write scenarios. Toshiba is also offering model options with self-encryption features.

Toshiba will start providing samples of the AL13SX 12.0 Gbit/s SAS interface enterprise HDD and Advanced Format enterprise HDD later this month.
