The Western
Digital SN750 SE is a solid-state drive in the M.2 2280 form factor, launched
on May 26th, 2021. It is available in capacities ranging from 250 GB to 1 TB.
This page reports specifications for the 1 TB variant. With the rest of the
system, the Western Digital SN750 SE interfaces using a PCI-Express 4.0 x4
connection. The SSD controller is the PS5019-E19-35 from Phison, a DRAM cache
is not available. Western Digital has installed 96-layer TLC NAND flash on the
SN750 SE, the flash chips are made by Toshiba. To improve write speeds, a
pseudo-SLC cache is used, so bursts of incoming writes are processed more
quickly. The cache is sized at 70 GB, once it is full, writes complete at 990
MB/s. Copying data out of the SLC cache (folding) completes at 250 MB/s. Thanks
to support for the fast PCI-Express 4.0 interface, performance is excellent.
The SN750 SE is rated for sequential read speeds of up to 3,600 MB/s and 2,830
MB/s write; random IOPS reach up to 526K for reads and 678K for writes.
At its launch, the SSD was priced at 110 USD. The warranty length is set to
five years, which is an excellent warranty period. Western Digital guarantees
an endurance rating of 600 TBW, a typical value for consumer SSDs.

This was
purchased 6 months ago and installed into my QNAP NAS but very rarely used. It
mostly just sat in there in case I needed it for a backup but never really
needed it. Listing includes the thermal pad
