Toshiba today announced the next generation of high-capacity 3.5-inch form factor enterprise hard disk drive (HDD) - the MG04 series.
Engineered for midline and nearline business critical workloads, the MG04 series is the industry's first enterprise capacity category models supporting industry standard 4K Advanced Format sector technologies as well as persistent write cache technology, which improves both performance and reliability. The series is engineered for the high-capacity demands of mid-tier servers and cloud application workloads and for capacity-optimized data center storage systems that benefit from high capacity per spindle.
With a 6 Gb/s interface model, the SAS MG04SCA and SATA MG04ACA series are available in the industry standard 3.5-inch form factor and are available in capacities of up to 5 TB. Spinning at 7,200 rotations per minute (RPM), the MG04 series delivers high application performance, while the high capacity per spindle saves rack space and reduces the footprint and operational burden of business critical servers and storage systems. The series also provides, as an option, persistent write cache technologies that help protect against data-loss in the event of sudden power loss, while also helping to improve performance and data reliability. Models supporting sanitize instant erase (SIE) option are available.
Customer samples of the MG04 series will begin shipping in February 2014.
The Toshiba MG04 enterprise class HDD series delivers massive 5TB capacity using industry standard 4K sector length technologies, models supporting either Advanced Format 512e emulation of legacy sector lengths, and the latest industry standard 4K native sector length technologies for optimum performance. The drives are quoted with a 4.17ms average latency time, 8.5-9.5ms read/write seek time and a sustained transfer speed of 205 MiB/s. MTTF is at 1.2m hours, with idle power quoted as 6.2W, with 11.3W during read/write operations. The internal buffer for SATA drives is set at 128 MiB, with SAS drives having 64 MiB.
