The Lenovo Legion Go is a solid-state drive in the M.2 2242 form factor, launched on October 31st, 2023. It is only available in the 1 TB capacity listed on this page. With the rest of the system, the Lenovo Legion Go interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the 20-82-10081-A1 Polaris MP16+ from WD, a DRAM cache is not available. Lenovo has installed 112-layer TLC NAND flash on the Legion Go, the flash chips are made by Kioxia. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The Legion Go is rated for sequential read speeds of up to 5,150 MB/s and 4,900 MB/s write; random IO reaches 740K IOPS for read and 800K for writes.
At its launch, the SSD was priced at 749 USD. The warranty length is set to five years, which is an excellent warranty period. Lenovo guarantees an endurance rating of 400 TBW, a relatively low value compared to other SSDs.

SDDQTQD-1T00 offer Security Encription
MTBF: 1.75 Millions of Hours

NAND Die:

Although this Die is a 4-plane design, most Kioxia BiCS5 NAND Dies used in most SSDs are dual planes design because of Yield and production cost.
And because of the die being dual-plane the Throughput is cut in half to 66 MB/s per die.
There is no CuA (Circuitry under Array) in the Dual-Plane variant.
Typical Endurance: 1700 ~ 3000 P.E.C.
Typ. Endurance eTLC: 5.000 ~ 7.000 P.E.C.
