TOSHIBA 25 日宣佈正式量產基於 3D 堆疊技術的 BiCS NAND Flash 及自家研發的 QLC (Quad-Level Cell) ，全新的 NAND FLASH 技術可以進一步降低 SSD 儲存容量成本，同時亦令 SSD 產品容量追上傳統機械硬碟，預計三年內企業用 SSD 產品將會提升至 128TB 容量。

據了解， TOSHIBA 將會加速推動 SSD 容量發揮，傳統 HDD 的儲存容量優勢不再，計劃量產自家研發的 QLC (Quad-Level Cell) 及 BiCS 3D NAND Flash 堆疊技術，雖然 SSD 容量開始追上傳統 HDD ，但寫入壽命仍然是 NAND Flash 技術的主要問題，高容量企業用 SSD 主要用作應付大量讀取的伺服器應用為主。

TOSHIBA 預期三年內 128TB 容量 SSD 將會普及於數據中心，現時 TOSHIBA 已擁有單顆 16 Die 堆疊 NAND Flash ，容量高達 512GB 的 NAND Flash ，預期單顆 1TB NAND Flash 可望在明年底正式量產，而只需 128 顆就能達成 128TB 容量。

New types of NAND flash memory will not only help to reduce costs of non-voltatile memory, but will also enable makers to build solid-state drives with unprecedented capacities. Toshiba Corp. believes that SSDs with 128TB capacity will become available commercially already three years from now.
In the coming years Toshiba plans to start production of quad-level cell (QLC) and BiCS [bit cost scalable] 3D NAND flash, which will greatly reduce costs of its non-volatile memory. Besides, the new types of NAND flash will also help to increase capacities of NAND flash memory chips and products on their base.

At a recent event Toshiba demonstrated plans to release solid-state drives with whopping 128TB capacities in 2018, reports Nordic Hardware. Such drives will be based on QLC or BiCS NAND flash memory. Toshiba will also have to use all-new controllers for such drives. Besides, it is highly likely that owners of datacentres will have to upgrade their software to take advantage of such SSDs.

Toshiba is confident that capacities of solid-state drives will be considerably higher than capacities of leading-edge hard disk drives. Toshiba does not reveal how much a 128TB SSD can cost three years from now, but it is likely that the price of such solid-state drives will be considerably higher than the price of multiple hard disk drives of such capacity.

KitGuru Says: While it is possible to create 128TB solid-state drives, it is impossible to build a lot of them because NAND flash manufacturing capacities are constrained. As a result, 128TB drives will be sold only to select customers in 2018 and will hardly reach the mass market three years from now.
