PCIe 4.0 hard disk is also the best breakthrough for AMD to push PCIe 4.0 technology. At present, there are two companies in Group and Huirong that have launched PCIe 4.0. The group's PS5016-E16 has the most complete technology and the highest performance. Dual-core CoXProcessor processor with 8 channels and 32 flash chips, interface data rate of 800MT/s, continuous read and write performance of up to 5GB/s, 4.4GB/s, up to 43% compared to PCIe 3.0 x4, 33%.
Huirong's first PCIe 4.0 x4 main control model is SM2267G supporting NVMe 1.3 specification, supporting SLC cache, DRAM cache, LDPC error correction, E2E protection and RAID engine, but the continuous read and write speeds are 4000MB/s and 3000MB/s respectively. Random read and write is 400K, 400K IOPS, the performance is worse than the group E16 master control, and the subsequent optimization, and the time to market is later than the E16 master, to wait until next Q2 quarter.
From the Taipei Computer Show to the present, there are at least seven SSD hard drives for PCIe 4.0. The GALAXY, Gigabyte, Corsair, Bodi, Essencore/Klevv, PNY and other vendors have released or demonstrated their own PCIe 4.0 hard drives. Q3 will be officially listed in the quarter.
PCIe 4.0 hard drives are still new, and more vendors need to be promoted, especially upstream NAND flash vendors. Toshiba's US company TMA recently demonstrated the prototype and samples of the PCIe 4.0 hard disk at the PCIe SIG's compliance seminar. The PCIe 4.0 NVMe hard drive passed the PCI-SIG FYI Gen 4 of the PCI-SIG organization. Compatible test.
Toshiba did not mention the specific performance and capacity, specifications and other parameters of their PCIe 4.0 NVMe hard drive, but Toshiba has already stated its close cooperation with PCI-SIG and other members to promote the release of PCIe 4.0 SSD hard drives as planned.
