Kioxia 2nd Gen XL-NAND Flash Memory up to 13.5 GB/s Seq Reads and 3M IOPS Random Reads
During the 2023 China Flash Market conference (CFM), Kioxia revealed its newest enterprise SSD powered by 2nd Gen XL-NAND flash memory. This cutting-edge technology promises sequential read speeds of up to 13.5 GB/s on drives featuring PCIe Gen 5 x4 interfaces.
This is a significant improvement over the first generation of Gen 5 SSDs, which only offer speeds of 12-12.5 GB/s. Kioxia's latest offering also boasts an impressive 118% increase in performance compared to its current crop of Gen 4 x4 SSDs. Additionally, the drive offers sequential write speeds of up to 9.7 GB/s. While sequential speeds are impressive, enterprise customers prioritize 4K random-access performance. Here, the drive offers up to 3 million IOPS random reads, with up to 1.06 million IOPS sequential writes.
Despite the impressive performance gains, read-latency has been slightly reduced to 27 µs, compared to 29 µs for the previous generation. Kioxia anticipates that PCIe Gen 5 and CXL 1.0 will continue to be the leading I/O interfaces for enterprise SSDs until the end of 2025. However, by 2026, PCIe Gen 6 is expected to emerge in the enterprise space, promising a doubling in interface bandwidth.

You might want to consider cryostasis because it seems you might be in for a few decades worth of sleep

Optane is still alive

900p is 350 MB/s 4k random read @ qd=1. Optane 5800x is 400+

Optane P5811X is coming...

That was the entire point behind the first generation product, but I never saw any drives hit retail. They seem to have only aimed at enterprise much like where Optane ended up. It's a big improvement over standard NAND.

Wake me when random R/W are getting better than the 150/50 i can get from a 6y old SSD.
