- Toshiba maps path for arduous disk drives from 24TB capability to 55TB & past
- Storage big targets 40TB drives as early as subsequent yr with new applied sciences
- Twelve platter design underpins Toshiba’s push towards greater capacities
Toshiba has outlined plans to push arduous disk capability far past at this time’s limits, with new slides displaying a path to 40TB fashions and an eventual transfer towards 55TB and past.
PC Watch says the corporate detailed its roadmap at a current symposium in Japan, describing advances in platter counts, recording applied sciences, and supplies that may form its subsequent technology of information middle drives.
There was a gentle rise in HDD storage sizes from 2017’s 10TB fashions to at this time’s 24TB capability. Toshiba raised density by shifting from CMR designs to its FC MAMR system, increasing platter counts from seven to 9 after which to 10. It later elevated density once more with refinements to each CMR and MAMR, reaching 22TB and 24TB capacities in 2024.
MAMR and HAMR
In October, we reported that Toshiba had verified a 12 disk stacking design for nearline drives, marking a primary for the storage trade.
This strategy provides two platters to the acquainted ten disk format and replaces aluminum substrates with glass, permitting thinner disks, finer tolerances, and higher sturdiness.
Toshiba paired the design with MAMR and stated it deliberate to succeed in 40TB capacities in 2027.
The brand new slides, considered one of which may be seen above, broaden on that plan. Toshiba nonetheless goals to ship a 40TB class drive in 2027 utilizing MAMR with 11 or 12 platters. A separate monitor, primarily based on HAMR, is ready to move 40TB in 2026 with 11 platters.
MAMR and HAMR are two approaches to vitality assisted magnetic recording that elevate storage density past what typical strategies permit.
MAMR makes use of a microwave subject to stabilize the writing course of so knowledge may be written to smaller magnetic areas with out dropping accuracy.
HAMR depends on a tiny, exactly managed burst of warmth from a semiconductor laser to momentarily decrease the resistance of the media, enabling even finer magnetic patterns.
Each strategies let producers pack extra knowledge onto every platter, though HAMR typically gives greater long run density positive aspects.
The roadmap reveals targets of 45TB in 2028 and 55TB or extra after 2029 as HAMR and 12 platter stacking mature, pointing towards what can be among the many largest arduous drives in the marketplace.
The corporate has stated it believes going to 13 platters may very well be possible throughout the similar format.
