Lexar SSD PCIe Gen4x4 M.2 NVMe 2280 with Graphene Heat Dissipation Sheet, PS5 Verified, R:7400MB/s W:6500MB/s NM790, High Durability 3D NAND, Domestic Genuine Product

This is an OWC SSD enclosure with a 4TB SSD installed.
Used for about 1 year, it is very stable. I own 3 of these, but 2 are sufficient, so I am selling this one.

Even when copying several TB for extended periods, the speed hardly decreases.
Please see the images for actual speeds.
The photos shown are from the internet. There are no scratches at all.

Currently, the OWC 4TB genuine SSD appears to be priced around 160,000 yen.
The SSD is not a genuine OWC product, but I believe it has equivalent access speeds.
It achieves almost the maximum speed with USB4 compatible Thunderbolt connection.
It's a great deal with the high-speed enclosure included.

Thank you for looking.
