Kioxia announces Optane-class SSD


Recommended Posts


Kioxia has announced it’s sample shipping an FL6 storage-class memory SSD built with its XL-Flash NAND technology. 

This news has been a long time coming as Kioxia first announced its XL-Flash technology back in 2019. It used BiCS 4 flash with 96 layers, formatted as SLC (Single Level Cell; 1 bit/cell) and with a latency variously described as less than 25 and 20µs and down to 5µs. 


Kioxia’s announcement contains no executive’s quote and says the FL6 bridges “the gap between DRAM and TLC-based drives, making them well-suited to latency-sensitive use cases such as caching layer, tiering and write logging.”
