Toshiba Announces Next Generation 15,000 RPM Enterprise Performance Hard Disk Drives

New 2.5-inch HDDs in capacities up to 600GB with optional self-encryption

IRVINE, Calif. — The Storage Products Business Unit of Toshiba America Electronic Components, Inc., a committed technology leader, announces new additions to the enterprise capacity hard disk drives (HDD) – the AL13SXB and the self-encrypting AL13SXQ. With a 2.5-inch form factor, the AL13SXB and AL13SXQ have 15mm z-height and spin at speeds up to 15,000 rotations per minute (RPM), making the AL13SX series suitable for mission critical enterprise storage applications.

The AL13SX series comes in 300GB1, 450GB and 600GB capacities, and delivers high performance in 600GB capacity while supporting industry standard 512n sector lengths in a space efficient 2.5-inch form factor. The 4K native sector and 512e emulation models of the drives include Toshiba’s persistent write cache technology for improved data integrity and performance. Overall, the AL13SX series supports high storage density, saving rack space and reducing mission critical storage footprint and operational burden for enterprise customers.

“The 15,000 RPM disk continues to be the backbone of mission critical IT operations. Toshiba’s AL13SX doubles available capacity while preserving the low-latency and energy efficiency customers require,” said Don Jeanette, senior director of marketing at Toshiba Storage Products Business Unit. “While older 3.5-inch 15,000 RPM disk drives are withdrawing from the market, the AL13SX provides a clear migration path to 2.5-inch models with the same 600GB capacity and lower latency for improved performance with a significant power savings – a real win-win for the important mission-critical storage category2.”

1 Definition of capacity: Toshiba defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 230 = 1,073,741,824 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, such as Microsoft Operating System and/or pre-installed software applications, or media content. Actual formatted capacity may vary.

2 Comparisons are based comparing the AL13SX series and Toshiba’s prior generation MK01GRRR series.

3 Interface speed may vary depending on the host device, read and write conditions, and file size.

4 Read and write speed may vary depending on the host device, read and write conditions, and file size.
