512GB Portable SSD with Fingerprint

The UMEMORY PEM100 PRO is a 512GB external solid-state drive that connects via a Type-C interface. It features a built-in fingerprint sensor for hardware encryption and unlocks with a single touch. The drive uses TLC memory components and delivers sequential read speeds up to 458 MB/s and write speeds up to 209 MB/s. Its orange enclosure measures 33 by 20 by 20 millimetres and weighs 200 grams.

Who This Suits and Who Should Look Elsewhere

This drive suits users who want pocket-sized, encrypted storage for phones, laptops, and desktops without remembering passwords. The splash-proof, UDP-packaged build operates from minus 25 to 80 degrees Celsius, helping data survive harsh environments. Buyers needing sustained write throughput above 209 MB/s or capacities larger than 512GB should consider other options.

Deciding Specification: Fingerprint Encryption

The integrated fingerprint reader is the feature that determines whether this SSD fits your workflow. It provides driver-free, cross-platform locking for personal files, research data, or enterprise documents. If biometric unlocking is not required, a standard portable SSD without the sensor will cover the same capacity and speed at lower complexity.

Questions about this item

How often should the TLC memory cells be checked or the drive replaced under normal use?

TLC NAND in a portable SSD is rated for thousands of program/erase cycles; with 512 GB capacity and typical consumer workloads the drive will last years before any cell wear becomes a concern.

What speed ceiling appears first when copying large files continuously to this 512 GB drive?

Sustained writes are limited to the 209 MB/s sequential write figure, so that throughput ceiling is reached before the 450 MB/s read limit during long transfers.

Does the fingerprint sensor or controller generate noticeable heat or fan noise during all-day operation?

The drive has no moving parts and operates from -25 °C to 80 °C; in normal room temperatures it stays cool and completely silent.
