The Transcend StoreJet 25S3 is a compact external enclosure designed to turn your 2.5-inch SATA HDD or SSD into a portable drive. Its silver aluminum casing provides a sturdy shell that helps dissipate heat passively, while the lightweight design weighing only 86 g makes it easy to slip into a bag for daily travel. Inside, the device supports SATA III interfaces with speeds up to 6 Gb/s and accommodates drives up to 9.5 mm in height. By utilizing a USB 3.1 Gen 1 external interface and UASP technology, you can achieve faster data transfer rates than standard USB connections allow. The enclosure is bus-powered via its USB Type-A connector, meaning you only need the included USB 3.0 Micro-B cable to start moving your files without needing an extra power adapter.
