Capacity and audience

The UMEMORY PEM100 PRO is a 512GB portable SSD designed for users who need secure, pocket-sized storage expansion for smartphones, laptops and desktop computers. Its fingerprint encryption suits professionals and privacy-conscious individuals who handle sensitive files on the move.

Build and connectivity

The drive measures 33mm by 20mm by 20mm and weighs 200g, with an orange UDP-integrated shell rated for splash-proof and water-resistant protection. A Type-C connector provides direct attachment to mobile devices, PCs and Macs without extra cables, and the unit operates from -25°C to 80°C.

Interface limits

The Type-C interface delivers sequential reads up to 450MB/s and writes up to 209MB/s, so large 4K video transfers take longer than on drives with faster protocols. Buyers who need sustained throughput above these figures or who require a larger single-volume capacity will find this model insufficient.

Questions about this item

What read speed does the Type-C interface on the PEM100 PRO actually deliver?

The drive reaches a maximum sequential read of 458 MB/s and a write of 209 MB/s over its Type-C connection.

Will the 33 mm by 20 mm orange drive fit on my keyring or in a small pocket?

At 33 mm wide, 20 mm deep and 20 mm high, the drive is fingertip-sized and weighs 200 g, so it slips onto a keychain or into a coin pocket easily.

How do I set up the fingerprint unlock on the PEM100 PRO without losing access?

Plug the drive into a Type-C port, scan the QR code to install the backup app, then register your fingerprint in the app before storing data; skipping the app registration is the step that locks users out.
