Dual Bay 2.5/3.5 inch HDD/SSD Stand New, Unused

Purchased on Amazon in February of this year for 4,399 yen.
Embarrassingly, I misunderstood its function and ended up not using it.
As shown in photos 8 through 10, it has not even been removed from its bag.
It is genuinely new and unused.
I have included the URL for the Amazon product page, so please refer to it for the actual appearance and specifications.

- Supports up to 32TB and features a plug-and-play design that is recognized instantly just by inserting and removing.
- Equipped with a USB 3.0 interface (maximum transfer speed 5Gbps), supporting UASP and TRIM functions. This improves data transfer efficiency, enabling high-speed reading/writing and maintenance, especially when using SSDs.

The progress can be checked on the four LEDs on the front, allowing for easy complete disk duplication. (Note: The capacity of drive A must be equal to or greater than drive B. If drive B has bad sectors, copying may fail.)
