Toshiba Debuts 12Gb SAS Enterprise 600GB 15,000rpm HDD
One year after HGST and Seagate
This is a Press Release edited by StorageNewsletter.com on March 16, 2015 at 2:24 pmThe Storage Products Business Unit of Toshiba America Electronic Components, Inc. announces the addition of 12Gb SAS interface 512 native and Advanced Format models to its 15,000rpm enterprise performance class HDD model line.
These additions are designed for mission-critical workloads, delivering the benefits of 12Gb 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 12Gb 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 power-saving, low-latency 2.5-inch form-factor. The 600GB is a 100% capacity increase over Toshiba’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 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 15,000rpm, the 12Gb SAS host interface delivers up to twice the host transfer bandwidth as older 6Gb SAS models. The AL13SX Series offers the same 600GB capacity as legacy 3.5-inch 15,000rpm 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 15,000rpm 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 12Gb over prior 6Gb models,” said Scott Wright, director of disk drive product marketing, 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 6Gb SAS to a faster, 12Gb SAS infrastructure to improve I/O performance,” according to John Rydning, IDC research VP for HDDs. “Toshiba’s new enterprise performance 12Gb SAS interface 15,000rpm 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 12Gb SAS interface enterprise HDD and advanced format enterprise HDD will be available later this month.
Comments
Enterprise 15,000rpm HDDs are competing hardly with SDDs but Toshiba, involved in the two technologies, debuted its first disk drive unit at 600GB with 12Gb SAS interface, following its MKxx01GRRB/R at 300GB with 6Gb SAS, released in November 2011 .
No there are three sources for these high-end enterprise HDDs ,all of them with three platters and six heads in 2.5-inch form factor 15mm high.
Seagate revealed in February 2014 its 600GB Enterprise Performance at 15,000rpm with 6Gb SAS, now available with 12Gb SAS.
WD's subsidiary HGST announced the same month the 600GB C15K600 12Gb SAS device.
