Product Description: Thank you for viewing. This is the TerraMaster D4-320, a 4-bay HDD enclosure compatible with USB 3.2 Gen2. [Reason for selling/Usage period] I purchased this new on March 12, 2025. (I cannot provide the invoice as it contains personal information). The usage period is less than a year. I am selling it because I have introduced a separate NAS. The fan area and the main body have been cleaned, and it is in a clean condition with no noticeable scratches. [Regarding the bonus HDD] I will include one 2TB Western Digital HDD (WD2000FYYZ / Enterprise Class) as a bonus and send it installed. *Important* This HDD shows "Caution" in the SMART information. Please consider it only for "operation check" or as a "bonus." *Even if you do not need the HDD, the price will not change, but if you do not need it, please let me know via the transaction message after purchase, and I can ship the "case body only." [Product Features] High-speed transfer: Compatible with USB 3.2 Gen2 (10Gbps). Large capacity support: Supports up to 88TB (22TB x 4). Easy removal: HDD installation is tool-free. Quiet design: Equipped with an auto-adjusting fan for quiet operation. No RAID support: This is a "single disk mode" only device without RAID function. Each HDD is recognized as an individual drive. [Accessories] Main unit Power adapter USB Type-C to C cable (or A to C, all contents of the original box) Quick guide Original box (All accessories at the time of purchase are included) [About Shipping] The product will be placed in the original box, carefully packed with cushioning materials, and shipped via Rakuraku Mercari. As it is a relatively new model, how about using it for PC data backup or capacity expansion? Thank you for your consideration. #TerraMaster #HDDcase #ExternalHDD #DAS #D4-320 #USBTypeC
