In context: This week, Kioxia unveiled an industry-showtime PCIe 5 SSD for data centers. Advancements in PCIe applied science are advancing pretty speedily, as consumers accept only just started working with PCIe 4, and PCIe 6 is already visible on the horizon.

Kioxia unveiled its new E3.S SSDs this calendar week. Specifications show non but that it is moving to PCIe five merely besides to a new course gene. The visitor didn't specify when the E3.S drives will exist widely available, but select OEM customers can sample them now.

The drive'southward maximum capacity is seven.68 terabytes. In add-on to PCIe v, Kioxia optimized them for 2x PCIe lane performance. The company says the maximum read throughput is effectually 6.5GB/s with ane,050K random read IOPS. The read and write latencies are 75μs and 14μs, respectively. Kioxia claims that read latency is 17 percent lower than its PCIe 4 SSDs and lx percentage lower for write latency.

The E3.S series is also moving over to the Enterprise and Datacenter Standard Form Factor (EDSFF). Kioxia says that compared to the 2.5" course factor information technology used before, EDSFF will characteristic improved heat management, let for higher ability budgets, better bespeak integrity, and work with future data center architectures.

In September, Kioxia held a presentation detailing PCIe 5 and mentioned speeds of upwardly to 14GB/due south. Nevertheless, information technology admitted that those wouldn't be replacing PCIe 4 anytime soon. Data centers are moving towards PCIe 5 fifty-fifty though consumers are merely at present upgrading to PCIe four SSDs for their abode computers and PlayStation 5s. Current consumer software isn't really maxing out PCIe 4 speeds yet, every bit recent game benchmarks evidence. Fifty-fifty still, the final draft specification for PCIe 6 came out last month, laying the roadmap for PCIe fifty-fifty further in the futurity.
