Buffalo HD-AD3U3 External Hard Drive HDD 3TB Failure Prediction Mimamori Aizu nasne This is a beautiful item with little use. A 3TB USB 3.1 external HDD. Supports both vertical and horizontal placement. It supports the failure prediction service "Mimamori Aizu," which accumulates self-diagnostic function "S.M.A.R.T." information in the cloud to understand the drive's status. In addition to the conventional fanless design, further noise reduction is achieved by closing the ventilation holes that cause sound leakage. Interface: USB3.2(Gen1)/3.1(Gen1)/3.0/2.0 Connector: MicroB I am not considering price negotiations.
