Contamination leads to the loss of over 6.5 Exabytes of WD and Kioxia 3D NAND

pcgamer.com:

It seems like the tech we love just keeps taking punches to the gut, leading to lower supply or higher prices, or both. Now comes word that Kioxia (formerly Toshiba) and Western Digital have reported that contamination issues have been detected at its NAND production facilities. Western Digital claims that the contamination impacted up to 6.5 exabytes of flash memory. That’s 6.5 million terabytes. The loss of that much NAND will no doubt have a market impact. 

Kioxia’s statement comes via Tom’s Hardware. It says that operations were affected at its Yokkaichi and Kitakami plants. The loss was attributed to a component containing impurities involved in the production of BiCS 3D NAND flash memory. That led to a halt in production.

Western Digital’s statement contains the estimated 6.5 exabyte figure. Both statements avoid giving a timeline for the resumption of production, but given the stoppage happened in ‘late January’ and it may not restart for some time to come, it's clear that the issue is a major one, with ripple effects likely to follow for several months, eventually leading to a shortage of BiCS NAND and a rise in the prices of the company’s SSDs.
