For modern enterprise and nearline 3.5-inch HDDs, Toshiba’s MG09-series drives uses a motor with a 7200-RPM spindle speed. The HDDs are also equipped with a 512 MB buffer and are rated for a 281 MB/s maximum sustained data transfer rate. Unfortunately, Toshiba has not updated the random access performance of the new products, though it is likely that their per-TB IOPS performance is lower when compared to predecessors. The manufacturer will offer its new drives both with SATA 3.3 (6 Gbps) and SAS 3.0 (12 Gbps) interfaces as well as a selection of logical data block length.
One of the noteworthy things about Toshiba’s MG09-series FC-MAMR HDDs is their power consumption. In active idle mode, they typically consume 4.16/4.54 Watts (SATA/SAS models), which is considerably lower when compared with Seagate’s Exos X18 as well as Western Digital’s Ultrastar DC HC550. As far as power consumption efficiency at idle (large hard drives could spend plenty of time idling) is concerned, the 18 TB MG09 is an undeniable champion consuming just 0.23 Watts per TB (in case of the SATA version). Meanwhile, the new drives are rated for 8.35/8.74 Watts (SATA/SAS SKUs) during read/write operations, which is higher when compared to the DC HC550 as well as predecessors from the MG07 and the MG08-series.
