Intel demonstrates PCIe 5.0 performance: hard drive speeds up to 13GB/s

In addition to the first DDR5 memory, Intel's 12th generation Core Alder Lake also debuted to support PCIe 5.0 technology, with a single channel rate of 32GT/s and an SSD hard disk speed of about 16GB/s, which is double that of the current PCIe 4.0 hard disk.

However, PCIe 5.0 is embarrassing that there are not many products now, almost no media has done PCIe 5.0 performance testing when Alder Lake first reviewed, Intel's own data is not much, chief performance strategist Ryan Shrout has just demonstrated the performance of PCIe 5.0 hard disks under Alder Lake.

The hard disk he uses is the enterprise-class PM1743 hard disk released by Samsung a few days ago, with a capacity of 1.92TB, a maximum of 15.36TB, PM1743 sequential reads up to 13000MBs/s, sequential writes 6600MB/s, random read 2500K IOPS, random write 250K IOPS.

From Intel's running score, on the Alder Lake platform, the speed of PM1743 easily ran above 13GB/s, and the highest was close to 14GB/s, which is almost the upper limit of PCIe 5.0, and the compared Western Digital black disk speed is about 7GB/s.

12th generation Core PCIe 5.0 is actually for graphics cards, PCH South Bridge chip has not yet supported PCIe 5.0, but motherboard manufacturers will convert PCIe 5.0 to M.2 slot, now it seems that playing PCIe 5.0 hard disk performance is no problem.

For PC users, the main problem is that there is no consumer-grade PCIe 5.0 hard disk, Samsung, Armor and other manufacturers launched or enterprise-level, in a few days of CES 2022 exhibition may see more consumer-grade PCIe 5.0 hard disk.
