Toshiba America has unveiled 12.0 Gbit/s1 SAS interface 512 native and Advanced Format models to its 15,000 RPM Enterprise Performance Class HDD model line – targeting mission-critical workloads.
Benefits include 12.0 Gbit/s SAS host transfer rate and enhanced power management features for integration with rack-optimized data centers.
Toshiba America said customer applications such as OLTP and databases will see better performance from faster host transfer rates using 12.0 Gbit/s SAS controllers. This apart, new AL13SX series models –supporting 4K native sector technology – will improve application performance in supported environments.
The company is offering AL13SX series in capacities up to 600GB in 2.5-inch form-factor. The 600GB is a 100 percent 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.
The 512n models offer industry migration to higher performing, more power and space efficient 2.5-inch form factor. Additional models supporting 4Kn or 512e Advanced Format sector lengths provide effective performance and data integrity.
The 12.0 Gbit/s SAS host interface delivers up to twice the host transfer bandwidth as older 6.0 Gbit/s SAS models with a speed of 15,000 RPM. 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 2.5-inch form-factor supports higher storage density, saving rack space and reducing the mission critical storage footprint and operational burden.
“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.
The company will be offering samples of the AL13SX 12.0 Gbit/s SAS interface enterprise HDD and Advanced Format enterprise later this month.
