The Seagate Nytro 5350H is a solid-state drive in the U.3 form factor, launched in 2022. It is available in capacities ranging from 1.9 TB to 7.5 TB. This page reports specifications for the 1.9 TB variant. With the rest of the system, the Seagate Nytro 5350H interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the PS5020-E20 X1 from Phison, a DRAM cache chip is available. Seagate has installed 128-layer TLC NAND flash on the Nytro 5350H, the flash chips are made by SK Hynix. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The Nytro 5350H is rated for sequential read speeds of up to 7,100 MB/s and 4,300 MB/s write; random IO reaches 1700K IOPS for read and 195K for writes.
The SSD's price at launch is unknown. The warranty length is set to five years, which is an excellent warranty period. Seagate guarantees an endurance rating of 3500 TBW, a good value.

Notes

Controller:

Could be more cores since Phison specifies "2 Cortex-R5 CPU cores" with "dozens" of CoXprocessors.
ARM 32-bit Cortex-R5 (2-core) + AndesCore 32-bit N25F RISC-V (32-core)
"The X1 SSD solution CPU complex is composed of two performance and power efficient ARM R5 CPUs and dozens of small CPU co-processors that complete computationally heavy, redundant tasks at high speed with a minimum of power consumption."

NAND Die:

Each die has 7 SGSs with 3 SGDs.
