Toshiba Electronics Europe (TEE) has expanded its 15,000rpm Enterprise Performance Class HDD model line with the release of 512 native and Advanced Format drives with 12Gb/s SAS interface. According to the company, customer applications such as online transaction processing (OLTP) and databases will gain enhanced performance from faster host transfer rates using 12Gb/s SAS controllers.

The devices are specifically designed for mission critical workloads, delivering the benefits of 12Gb/s SAS host transfer rate and improved power management features for integration with rack-optimised data centres. The models that support 4K native sector technology may further boost application performance in supported environments, added the company.

With a speed of 15,000rpm, the 12Gb/s SAS host interface delivers up to twice the host transfer bandwidth compared to older 6Gb/s SAS models.

AL13SX series

The AL13SX series is available in capacities up to 600GB in a power-saving, low-latency 2.5in form factor. The smaller form factor supports higher storage density, saving rack space and reducing the mission critical storage footprint and operational burden, noted Toshiba. The 600GB is a 100 per cent capacity increase over prior generation 2.5in models and provides faster seek performance and a lower power profile compared to legacy 3.5in 600GB models, the company revealed.

Models supporting 512 native sector length technology provide optimum compatibility with industry-standard applications and operating environments. The 512n models offer industry migration to higher performing, more power and space efficient 2.5in 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, Toshiba indicated.

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

Samples of the AL13SX 12Gb/s SAS interface enterprise HDD and Advanced Format enterprise HDD will be available later this month.
