UMEMORY PEM100 PRO 256GB portable SSD

This compact external solid-state drive provides 256GB of TLC flash storage with a Type-C interface. It is built for smartphone, laptop and desktop users who need secure, pocket-sized expansion without a separate power supply. The integrated fingerprint sensor adds hardware encryption for sensitive files.

Capacity and real-world headroom

The drive offers 256GB of usable space for photos, videos and documents. Sequential reads reach 458MB/s and writes 209MB/s, so large media transfers finish quickly. It will saturate the Type-C link before the controller becomes the bottleneck, and the single fingerprint slot limits shared access.

Type-C interface practical limits

The USB Type-C connection works with iOS, Android, Windows and macOS hosts. Performance tops out at the stated 450MB/s read ceiling, so faster host ports yield no extra throughput. The splash-proof, UDP-packaged chassis operates from -25°C to 80°C, but the tiny 33×20×20mm form factor rules out active cooling.

Questions about this item

Will the 33 mm wide Type-C drive work with my older USB-A laptop?

The drive uses a Type-C connector, so a USB-A to Type-C adapter or cable is required for older USB-A ports; the 450 MB/s read speed will be limited by the USB-A port's maximum throughput.

How can I verify the fingerprint sensor and 458 MB/s read speed are functioning after setup?

Register a fingerprint in the companion app, then lock and unlock the drive to test the sensor; run a benchmark tool to confirm sequential read speeds approach 458 MB/s on a USB 3.1 Gen 1 or faster port.

Does the 256 GB orange unit include a Type-C cable or must I buy one separately?

The product listing states "Package Content: Yes" but does not detail the included accessories; assume a Type-C cable is supplied, yet keep a spare cable handy in case only the drive itself is in the box.
