Kioxia Unveils Plans for a 13.5 GB/s-capable PCIe Gen 5 x4 Enterprise SSD
Kioxia, at the 2023 China Flash Market conference (CFM), unveiled its next-generation enterprise SSD powered by 2nd Gen XL-NAND flash memory that promises up to 13.5 GB/s of sequential reads on drives with PCIe Gen 5 x4 interfaces. This puts it higher than the 12-12.5 GB/s offered by the first crop of Gen 5 SSDs, and a 118% over its current crop of Gen 4 x4 SSDs. The drive also offers up to 9.7 GB/s of sequential writes.
4K random-access performance is of a lot more importance to enterprise customers, and here, the drive is said to offer up to 3 million IOPS random reads, with up to 1.06 million IOPS sequential writes. All this comes at a slightly reduced read-latency of 27 µs, compared to 29 µs for the previous generation. Kioxia also expects PCIe Gen 5 and CXL 1.0 to be the prominent I/O interfaces for enterprise SSDs from now until the end of 2025. It's only with 2026 that we could see the emergence of PCIe Gen 6 in the enterprise space, promising a doubling in interface bandwidth.
