Toshiba Debuts 12.0 Gbit/s SAS Enterprise Performance HDD

The AL13SX delivers mission critical disk drive performance in up to 600GB

IRVINE, Calif. — (BUSINESS WIRE) — March 11, 2015 — The Storage Products Business Unit of Toshiba America Electronic Components, Inc., a committed technology leader, announces the addition of 12.0 Gbit/s1 SAS interface 512 native and Advanced Format models to its 15,000 RPM Enterprise Performance Class HDD model line. These newest additions are specifically 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. Customer 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 600GB2 in a power-saving, low-latency 2.5-inch form-factor. The 600GB is a 100 percent3 capacity increase over 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 optimum 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. Model options with self-encryption features are also offered.

With a speed of 15,000 RPM, the 12.0 Gbit/s SAS host interface delivers up to twice the host transfer bandwidth as older 6.0 Gbit/s SAS models. The AL13SX Series offers the same 600GB capacity as legacy 3.5-inch 15,000 RPM enterprise HDDs but with lower latency and higher power efficiency. The smaller 2.5-inch form-factor supports higher storage density, saving rack space and reducing the mission critical storage footprint and operational burden.

“Drives with 15,000 RPM continue to be the backbone of mission critical IT operations, and Toshiba’s latest AL13SX models can double the SAS host interface transfer rate to 12.0 Gbit/s over prior 6.0 Gbit/s models,” said Scott Wright, director of disk drive product marketing at Toshiba Storage Products Business Unit. “Our customers demand performance and reliability in mission-critical storage as well as flexibility to support legacy storage applications and hardware – the AL13SX series meets these demands while also reducing operation burdens, delivering a real win-win for our customers.”

“Mission critical enterprise storage is transitioning quickly from 6 Gbit/s SAS to a faster, 12.0 Gbit/s SAS infrastructure to improve I/O performance,” according to John Rydning, IDC research vice president for hard disk drives. “Toshiba’s new enterprise performance 12.0 Gbit/s SAS interface 15,000 RPM HDDs, formatted with either native 512 or 4Kn (512 emulation) Byte sector formats, are a timely addition to its enterprise HDD product portfolio.”

Samples of the AL13SX 12.0 Gbit/s SAS interface enterprise HDD and Advanced Format enterprise HDD will be available later this month.
