This is a network-attached storage (NAS) device, the "LinkStation LS220D0402G" from BUFFALO. I purchased it new in September 2022, but I only powered it on once when I tried to set it up, and it has been stored in its box since then. Since it has not been used in practice, the HDD has hardly been used, and it is in very good condition. It is ideal for backing up smartphones and PCs, and for accessing data from outside the home. [Product Details] • Model Number: LS220D0402G • Capacity: 4TB (2TB x 2 drives) • Features: Supports RAID 1 (mirroring), a reliable model that protects data even in the event of a failure. • Purchase Date: September 2022 [Condition] • Frequency of Use: Only powered on once, in excellent condition. • Appearance: No noticeable scratches or stains, in near-new condition. • Operation: Power-on and normal operation confirmed.
