WD Announces Pilot Production of World's First 64-Layer 512 Gb TLC NAND

Toshiba may be in the ropes for now, but WD, one of its foremost partners (mainly due to its SanDisk acquisition) and most interested party in Toshiba's NAND spin-off efforts, has just announced that it is world first in actually producing a 64-Layer 512 Gb TLC NAND die. WD is developing and producing this 64-layer NAND at its Yokkaichi, Japan fab which it operates alongside - you guessed it - Toshiba, under their joint Flash Forward venture, though there is no indication as to when the new dies will hit full production. The addition of the latest BiCS3 iteration indicates that, despite its recent challenges and snags, Toshiba continues to execute on its semiconductor roadmap, which is certain to be a boon in keeping the value of its NAND production capabilities in the face of the confirmed spin-off and sell-off of a 20% stake on its NAND production business.

There has been some difficulty in achieving any significant ramp-up in 3D NAND production over at the WD-Toshiba venture, with WD having announced a 256 Gb version of the same BiCS 3 technology it employs on the new 512 Gb die last year, to no considerable volume of production. That's one of the reasons for the current NAND shortage and price rises, among other factors, so let's hope all goes well in this ramp up. If all goes well, 1 TB SSD's with 512 Gb TLC NAND dies for $150?

Only question I have is if they have an NVMe based controller to match it so we can have a good performing large drive. I am not currently impressed by the WD or Intel NVMe offerings.

As long as it's 3D TLC NAND it's gonna sell like hot cake, otherwise lukewarm reception at best
