New low power consumption hard drives introduced by Toshiba
Toshiba has introduced an industry first hard drive that features flux-control microwave-assisted magnetic recording (FC-MAMR) technology.
These new HDDs are designed for use in nearline and enterprise applications.
The drives offer an 18 TB capacity and feature ultra-low idle power consumption.
The MG09-series hard drives include both an 18 TB and 16 TB option.
The 18 TB HDD is 3.5 inches and has a nine-platter helium sealed platform with 18 heads. These heads have a microwave-emitting component which changes the magnetic coercivity of the platters before writing data.
The 16 TB MG09 version has 8 platters with 16 heads.
Both drives will be available with SATA 3.3 (5 Gbps) and SAS 3.0 (12 Gbps) interfaces.
Where the Toshiba MG09-series shines is in its power consumption aspect.
When the HDDs are in active idle mode, they will typically consume 4.16/4.54 Watts.
This is much lower than both Seagate’s Exos X18 and Western Digital’s Ultrastar DC HC550.
The new drives are rated for 8.35/8.74 Watts during their read/write operations.
Toshiba’s MG09-series HDDs are rated for a 550 TB average annualized workload and are covered by a standard five-year warranty.
These drives also support Toshiba’s persistent write cache (PWC) and feature power loss protection (PLP) technology.
Sample shipments of Toshiba’s new 18 TB MG09-series MAMR HDDs will begin by March 31, 2021.
