Compact 128GB Type-C SSD with fingerprint security

The UMEMORY PEM100 PRO is a portable solid-state drive that adds 128GB of storage to phones, laptops, desktops and Macs through a Type-C connection. Its built-in fingerprint sensor encrypts and unlocks data with one touch, targeting professionals and everyday users who need private, pocket-sized backup without installing software.

Silent operation with splash-proof durability

Having no moving parts, the drive runs completely silent and draws minimal power from the host device during normal file transfers. The UDP integrated packaging provides water-resistant protection, while the commercial-grade thermal design maintains reliable function across an operating range of -25°C to 80°C.

Consistent 450MB/s reads under sustained workloads

Sequential read speeds reach 458MB/s and writes reach 209MB/s, allowing extended transfers of large photo libraries or 4K video without the throttling typical of smaller flash drives. The LDPC error-correction controller keeps data integrity stable throughout long sessions, making it suitable for continuous field recording or full-disk backups.

Questions about this item

How do I set up the fingerprint unlock on the UMEMORY PEM100 PRO 128GB?

Connect the drive via its Type-C interface to your phone or computer, then follow the on-screen prompts in the companion app to register up to 100 fingerprints for one-touch unlocking.

What maintenance will the TLC memory and splash-proof build need over time?

No scheduled maintenance is required; keep the Type-C port clean and dry, and avoid sustained temperatures above 80°C or below -25°C to preserve the UDP packaging and TLC endurance.

At what point does the 450MB/s read speed drop during a long transfer?

The 209MB/s sequential write limit appears first; once the 128GB TLC buffer fills, sustained writes settle at that lower rate while reads stay nearer 458MB/s.
