Portable SSD for creative professionals

The SanDisk Extreme Pro SDSSDE82-4T00-G25 is a 4TB external solid-state drive built around a USB4 Gen 3x2 interface. It targets photographers, videographers and mobile professionals who need to move large project files quickly between Windows 10+ PCs, macOS 14+ Macs, Xbox Series X|S and PS5 consoles.

Plug-and-play with USB-C

Installation requires only the included USB Type-C to Type-C cable and a compatible Type-C port. The drive is backwards compatible with USB 3.2 and USB 2.0 hosts, though speeds fall to the host limit. No drivers are needed, but a port that cannot supply sufficient power may cause disconnects under sustained load.

4TB capacity with USB4 headroom

The 4TB volume holds extensive RAW photo libraries, multi-camera video timelines and full game installs. Sequential reads reach up to 3800 MBps and writes up to 3700 MBps on USB4 40Gbps ports. On USB 3.2 or USB 2.0 connections performance is limited by the older bus, and the drive does not support Thunderbolt 4 speeds despite compatibility.

Questions about this item

How can I verify the SSD is delivering the 3800 MB/s read speed after connecting it?

Run a benchmark tool such as CrystalDiskMark on a Windows 10+ or macOS 14+ system with a USB4 or Thunderbolt 4 port; the sequential read result should approach 3800 MB/s.

What accessories are included and which cable do I need to add for USB4 performance?

The box contains the 4 TB Extreme PRO SSD, a USB Type-C to Type-C cable and the quick install and warranty guides; no extra cable is required for USB4 speeds.

Which capacity should I choose if I need the full 3800 MB/s read and 3700 MB/s write figures?

The 4 TB model listed here is specified for up to 3800 MB/s read and 3700 MB/s write, so select this capacity to obtain those peak speeds.
