YMTC has begun shipments of its Zhitai TiPlus7100 SSDs based on its latest 232-layer 3D NAND Xtacking 3.0 memory with a 2400 MT/s interface, ITHome reports. This confirms that YMTC's latest 3D NAND memory — which is required to produce SSDs with a PCIe 5.0 x4 interface that fully saturate this interface and hit a 12.4 GB/s sequential read speed — is now in mass production.

YMTC's Zhitai TiPlus7100 are M.2-2280 PCIe 4.0 x4 drives designed to combine affordability with strong performance. The SSDs are to be available in 512GB, 1TB, and 2TB versions with the speediest rated for a sequential read speed of up to 7000 MB/s as well as a sequential write speed of up to 6000 MB/s.

When it comes to random performance, then 1TB and 2TB models are set to offer up to 900K random read IOPS as well as up to 700K random write IOPS. The TiPlus7100 drives do not carry any SDRAM buffer and uses a host memory buffer, which is an indicator that we are dealing with a reasonably priced product. Meanwhile, these drives can easily challenge the best SSDs available today.

Actually, the SAMSUNG 990 PRO (PCIe 4.0) already hit that

Experience up to 1400K/1550K IOPS, while sequential read/write speeds up to 7450/6900 MB/s reach near the max performance of PCIe® 4.0.

PCIe 5.0 M.2 SSDs are around the corner
