China Chipmaker YMTC Ships Xtacking 2.0 SSDs, Up to 6.2 GBps

Like other manufacturers of commodity 3D NAND, Yangtze Memory has evolved from a manufacturer of flash memory to a vertically integrated manufacturer of solid state storage solutions. The company started with simple SATA SSDs about two years ago and has since evolved to more advanced PCIe drives. And now it’s time for YMTC to enter the most lucrative 3D NAND market – enterprise storage.

YMTC’s first enterprise-grade product is PE310 SSD Offered in a 2.5-inch U.2 form factor with PCIe 4.0 x4 interface and using 3D TLC NAND memory, targeted for mixed workloads and designed for up to 3 drive writes per day up to 6.4 It offers TB of storage capacity. (DWPD) and drives up to 7.68 TB (drives targeted for read-intensive workloads and designed for up to 1 DWPD).

In terms of performance, the drive delivers up to 6.2 GBps sequential read speed, up to 4.5 GBps sequential write speed, up to 1 million read IOPS, and up to 380K/190K (mixed/read intensive workload) write IOPS To do. Phison’s PE310 is an enterprise-grade product, so the performance numbers listed represent sustained performance, not peak performance. The drives are very fast, but they are enterprise grade so I won’t include them in our list of the best SSDs available today.

Yangtze Memory’s 3D TLC NAND memory used in the PE310 drive features the Xtacking 2.0 architecture. Therefore, it supports maximum interface data transfer rates of up to 1,600 MT/s, matching what the latest 3D NAND ICs from manufacturers such as Samsung and SK Hynix offer.

YMTC has not disclosed the controller they use for their PE310 series products as they did months ago. The only thing Yangtze Memory mentions is that the PE310 series drive’s controller features his LDPC ECC, is NVMe protocol compliant, and supports AES-256 encryption. Additionally, the drive supports features such as power loss protection, advanced 8-level power management, end-to-end data protection (E2EDP), and thermal throttling.

Considering that YMTC deliberately disclosed very little about the PE310’s controller, including the NVMe versions it supports and the branding of its LDPC-based signal processing and ECC technology, the company ultimately decided to use We don’t want to reveal off controllers (in 2020 the company partnered with Phison for their client SSDs, but using chips from said vendors in the PE310 automatically doesn’t matter), early controllers and uses a highly customized version of an off-the-shelf controller that is largely irrelevant. Use a chip or a self-developed controller.
