What simply occurred? Seagate confirmed off a tough disk drive that connects by way of NVMe on the Open Computing Undertaking (OCP) world summit this week. Limiting a sooner PCIe connection to the speeds of a spinning disk drive is perhaps counterintuitive, however it might nonetheless have advantages exterior of client desktop use.
Seagate has detailed the mission on its weblog, together with the way it works and the attainable advantages. There’s additionally a separate doc that goes into extra depth in regards to the specs. Seagate plans to make it obtainable to prospects within the coming years.
Diagrams present the exhausting drive linked by way of PCIe3 and PCIe4, utilizing proof-of-concept enclosures. The HDD makes use of native NVMe ports, however Seagate says it has “Tri-Mode” SAS, SATA, and NVMe receivers.
Seagate plans to make it obtainable to “key prospects” in September 2022, with broader availability for single and dual-port fashions in the course of 2024.
The thought of an NVMe HDD could seem odd on its face. Shoppers have been shifting from HDDs to SSDs as a result of stable state know-how can learn and transfer knowledge sooner. The transfer in direction of connecting storage to motherboards by way of NVMe as an alternative of SATA elevated speeds much more. Utilizing an NVMe connection for an HDD could not present any pace advantages compared, and certainly Seagate’s rationalization does not point out the drive’s efficiency in any respect.
As a substitute, Seagate claims the principle advantages are price and ease, significantly for servers and workstations, which can nonetheless use HDDs loads as a result of they’re cheaper per gigabyte than SSDs. Going from SATA to NVMe means fewer shifting elements, making the drives extra inexpensive and fewer vulnerable to failure. Seagate additionally says these drives could scale extra simply and eat much less power.
