Toshiba reveals 30TB disk drive to arrive by 2024
I want to be your SledgeMAMR
Toshiba's fiscal 2023 ends on 31 March 2024.
The details were revealed in a Toshiba chart presented to analysts over two investor relations days this week in Tokyo ahead of Toshiba reporting its Q3 results for fiscal 2021 (ended 31 December '21) on February 14.
Analysts were shown Toshiba's HDD capacity roadmap, pictured above.
The slide revealed a 20TB drive in fy2021 – the current financial year, which ends on 31 March 2022 – and Toshiba has not yet announced such a product. We would envisage a 10-platter construction at the current (ie: 18TB 9-platter HDD) 2TB/platter level.
A 26TB drive is envisaged some time in fiscal 2022, so any time from April onwards.
The Reg thinks a 10 x 3TB or 11 x 2.7TB platter construction would be needed to reach the 30TB mark. Such a drive would place Toshiba ahead of both Seagate and Western Digital in capacity terms.
- Seagate, WD mull 10-platter HDDs as pitstop before HAMR, MAMR time
- MAMR Mia! Western Digital's 18TB and 20TB microwave-energy hard drives out soon
- 2021 in storage: We waited for a flash price revolution that never came. But about creativity? We can't complain
- Back up for a minute – Backblaze HD reliability stats show oldies can be goodies
Toshiba could intend to use shingling (overlapping wider write tracks to increase narrow read track density) but made no mention of this – we have asked the company for more details.
The chart also shows Toshiba introducing HAMR (Heat-Assisted Magnetic Recording) drives in its fiscal 2025, alongside MAS MAMR - both at the 35TB level. They are scheduled to expand beyond the 40TB level in Toshiba's fiscal 2026.
Toshiba's fiscal year runs from April 1 of a calendar year to March 31 of the next calendar year. Therefore, from "Fy 2023" indicates from April 1, 2023, until March 31, 2024. This is rather sooner than expected, to say the least.
We have asked Toshiba to clarify when its 30TB drive will appear. ®
