Everyday essential for digital files

The Samsung BAR Plus 128GB USB 3.1 Gen 1 Type-A flash drive in Titan Gray delivers read speeds up to 400MB/s and write speeds up to 100MB/s. A rugged metal casing protects data with water, shock, magnet, temperature and X-ray proofing. An integrated key ring helps prevent loss.

Fits any USB-A port from 2.0 upwards

The Type-A connector works with USB 3.1, 3.0 and 2.0 hosts without adapters. At 0.50" x 0.60" x 1.60" and 0.04 oz it adds negligible bulk to a laptop bag or pocket. The compact form leaves adjacent ports free on crowded hubs or slim ultrabooks.

Sustained transfers stay consistent

The drive moves a 3GB 4K UHD video file in roughly 10 seconds thanks to its 400MB/s read ceiling. Metal construction dissipates heat during long copy sessions so throughput does not throttle. Rugged proofing keeps performance stable across temperature swings and rough handling.

Questions about this item

How long can the drive sustain its 400 MB/s read speed before it slows down?

The drive is rated for up to 400 MB/s read and 100 MB/s write over USB 3.1 Gen 1; sustained throughput will depend on the host controller and file sizes.

Does the metal casing get hot or draw extra power during all-day transfers?

The rugged metal body acts as a passive heat sink and the drive draws standard USB bus power with no external adapter required.

What host port do I need to reach the advertised speeds?

A USB 3.1 Gen 1 Type-A port (also compatible with USB 3.0 and 2.0) is required to achieve up to 400 MB/s read and 100 MB/s write.
