The Transcend MTE250S is a solid-state drive in the M.2 2280 form factor, launched on October 26th, 2022. It is available in capacities ranging from 1 TB to 4 TB. This page reports specifications for the 1 TB variant. With the rest of the system, the Transcend MTE250S interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the SM2264F from Silicon Motion, a DRAM cache chip is available. Transcend has installed 112-layer TLC NAND flash on the MTE250S, the flash chips are made by Kioxia. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are processed more quickly. The cache is sized at 200 GB. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The MTE250S is rated for sequential read speeds of up to 7,200 MB/s and 6,200 MB/s write; random IOPS reach up to 530K for reads and 420K for writes.
The SSD's price at launch is unknown. The warranty length is set to five years, which is an excellent warranty period. Transcend guarantees an endurance rating of 780 TBW, a typical value for consumer SSDs.

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.
