From SLC to QLC: SSD with the biggest disadvantage becomes HDD’s strong opponent.

Source: local   Editor: Alex   Update Time :2019-01-12
The hard disk market has been monopolized by several major storage manufacturers in Japan, Korea and United States. However, domestic storage manufacturers represented by YMTC is catching up. Although SSD from SLC to QLC has much shortcoming in erasure times, improvement in capacity allow QLC SSD to catch up with HDD, perhaps achieving SSD $0.14 per GB.
