Toshiba this week introduced the business’s first arduous drive that includes flux-control microwave-assisted magnetic recording (FC-MAMR) know-how. The new MG09-series HDDs are designed primarily for nearline and enterprise functions, they provide an 18 TB capability together with an ultra-low idle energy consumption.
The Toshiba MG09-series 3.5-inch 18 TB HDD are primarily based on the corporate’s 3rd technology nine-platter helium sealed platform that options 18 heads with a microwave-emitting element which adjustments magnetic coercivity of the platters earlier than writing knowledge. The HD disks are made by Showa Denko Okay.Okay. (SDK), a long-time accomplice of Toshiba. Each aluminum platter is about 0.635 mm thick, it options an areal density of round 1.5 Tb/inch2 and might retailer as much as 2 TB of information. The MG09 household additionally features a 16 TB mannequin which presumably includes a decrease variety of platters (primarily based on the identical efficiency ranking).
For fashionable enterprise and nearline 3.5-inch HDDs, Toshiba’s MG09-series drives makes use of a motor with a 7200-RPM spindle velocity. The HDDs are additionally geared up with a 512 MB buffer and are rated for a 281 MB/s most sustained knowledge switch price. Unfortunately, Toshiba has not up to date the random entry efficiency of the brand new merchandise, although it’s possible that their per-TB IOPS efficiency is decrease when in comparison with predecessors. The producer will provide its new drives each with SATA 3.3 (6 Gbps) and SAS 3.0 (12 Gbps) interfaces in addition to a collection of logical knowledge block size.
One of the noteworthy issues about Toshiba’s MG09-series FC-MAMR HDDs is their energy consumption. In energetic idle mode, they sometimes eat 4.16/4.54 Watts (SATA/SAS fashions), which is significantly decrease compared with Seagate’s Exos X18 in addition to Western Digital’s Ultrastar DC HC550. As far as energy consumption effectivity at idle (giant arduous drives might spend loads of time idling) is worried, the 18 TB MG09 is an plain champion consuming simply 0.23 Watts per TB (in case of the SATA model). Meanwhile, the brand new drives are rated for 8.35/8.74 Watts (SATA/SAS SKUs) throughout learn/write operations, which is larger when in comparison with the DC HC550 in addition to predecessors from the MG07 and the MG08-series.

As the MG09 household of arduous drives are supposed for datacenter racks that accommodate tons of of vibrating HDDs, they function quite a few enhancements to make sure constant efficiency, reliability, and sturdiness. Typically such enhancements embody prime and backside connected motors, RVFF, in addition to environmental sensors. Like all fashionable drives for 24/7 functions, Toshiba’s MG09-series models are rated for a 550 TB common annualized workload, 2.5 million hours MTBF, and are lined with an ordinary five-year guarantee.
Also, the brand new MG09 arduous drives help Toshiba’s persistent write cache (PWC) with energy loss safety (PLP) know-how, which is essential for 4K sector drives that emulate 512B sectors. The PWC with PLP function guards knowledge in case of energy loss whereas performing read-modify-write (RMW) operation to align the supply write request with the bodily sectors it has to switch….
