The Transcend StoreJet 25H3 is a portable external hard drive with a 2 TB capacity, designed to keep your large files and backups safe while you are on the move. This purple drive uses a 2.5" HDD and connects via a USB 3.1 Gen 1 interface, providing fast data transfers through the included micro USB to USB Type-A cable. To protect your data from accidents, it features a three-stage shock protection system consisting of a silicone rubber case, a reinforced hard shell, and an internal suspension damper, which has earned it the MIL-STD-810G US military transit drop test certification. Measuring 131.8 mm x 80.8 mm x 16.3 mm and weighing only 191 g, the device is compact enough to fit easily into a bag for daily commutes. It includes a convenient one-touch auto-backup button for quick file saves and supports 256-bit AES encryption to keep sensitive information private. You can manage your data using Transcend Elite software for cloud backups and disk locking, or use RecoveRx to retrieve lost files. The drive is compatible with Windows 7 or later and macOS 10.10 or later, making it a versatile choice for users who need reliable, rugged storage across different operating systems.
