Silicon Power Bolt B75 Pro 4TB Portable External SSD (SU040TBPSD75PSCKBH) – USB 3.2 Gen 2, USB Type-C

The Silicon Power Bolt B75 Pro 4TB (SU040TBPSD75PSCKBH) is a portable solid state drive with USB 3.2 Gen 2, USB Type-C connectivity. Designed for photographers, creators, students and travellers, it carries large files securely and moves them far faster than a portable hard drive.

Fast, pocket-size storage for work on the move.

Why Portable SSDs Replace Portable Hard Drives

Portable hard drives are slow, heavy and vulnerable to drops because they contain spinning platters. Moving a day of 4K footage or a large photo shoot can take a long time, and one fall can cost the data.

The Silicon Power Bolt B75 Pro 4TB uses flash memory with no moving parts, so it is faster, lighter and more resistant to bumps. It slips into a pocket or bag for daily use.

Fast, Simple Connections

Connect over USB 3.2 Gen 2, USB Type-C to laptops, desktops and many tablets and phones. Actual speed depends on your computer’s USB or Thunderbolt port.

Built for Everyday Carry

A compact, solid-state design means no clicking, no spin-up delay and better resistance to drops than portable hard drives.
