Toshiba has introduced the trade's first 16 TB capability exhausting drive. The MG08 collection drives are designed for nearline functions and use two-dimensional magnetic recording know-how (TDMR) to supply constant and predictable efficiency.
Toshiba's MG08 three.5-inch helium-filled exhausting drives are based mostly on 9 1.7 TB PMR disks manufactured by Showa Denko Okay.Okay. (SDK) and 18 Reader / Author TDMR heads developed by TDK. The exhausting disk has a spindle pace of 7200 rpm, a 512 MB DRAM buffer and a 6 Gbps SATA interface or SAS 12 Gbps (relying on the mannequin). With MG08 exhausting drives concentrating on nearline functions that use lots of of exhausting drives per rack and heavy vibration, the exhausting drives characteristic high and backside mounted motors, RVFF, environmental sensors, and different improvements that enhance reliability and guarantee constant efficiency
Like different Toshiba nearline drives, the brand new MG08 collection helps the corporate's everlasting write cache (PWC) with Energy Loss Safety (PLP), which is essential for 4K sector drives that emulate 512B sectors , The PWC with PLP operate protects knowledge within the occasion of energy failure whereas a learn, modify and write (RMW) operation is carried out to match the supply write request with the bodily sectors that should be modified. With RMW, Toshiba can deal with clients working older methods with excessive capability factors.
Toshiba's MG08 drives are a collection of trade firsts. Initially, Toshiba is the one firm worldwide that makes use of a nine-disk HDD design. It was mandatory with its 14TB exhausting drives because the firm didn’t use TDMR (in contrast to Seagate). Second, the MG08 makes use of SDK PMR plates with a Z top of zero.635 mm. That is lower than zero.8mm plates usually used for eight-plate designs. Third, TDMR heads developed by TDK are used, permitting Toshiba to make use of these disks.
Surprisingly, Toshiba doesn’t announce efficiency figures for its newest drives (probably as a result of the firmware continues to be down), however it’s logical to imagine that the brand new drives are quicker than their predecessors, in addition to random learn / write operations resulting from elevated areal density Cache and different components.
Toshiba charges its MG08 exhausting drives with a mean annual load of 550TB, an MTBF of two.5 million hours, and a five-year customary guarantee. Toshiba's companions want 4 to 6 months to validate the brand new disks earlier than deployment. Subsequently, the mass manufacturing of MG08 exhausting drives will begin in just a few months.
