Manufacturer description
The SanDisk 4TB Extreme PRO Portable SSD is built for creators and gamers who move large files fast and refuse to baby their gear. Its NVMe internals push read and write speeds of up to 2000MB/s over USB-C (USB 3.2 Gen 2x2), so multi-gigabyte video projects, RAW photo libraries, and Steam installs transfer in a fraction of the time a SATA portable drive needs. What separates this SanDisk portable SSD from cheaper plastic enclosures is the forged aluminum chassis: it doubles as a heatsink, holding higher sustained speeds during long transfers instead of throttling partway through. A silicone…

Frequently Asked Questions
Does the SanDisk Extreme PRO 4TB really hit 2000MB/s?
Up to 2000MB/s read and write is the rated figure, and reaching it requires a host port that supports USB 3.2 Gen 2x2. On slower USB-C ports the drive still works, just at that port's ceiling.
Is this drive waterproof enough to take outdoors?
It carries an IP65 water and dust resistance rating and is rated for drops of up to 3 meters. A carabiner loop lets you clip it to a pack, so it is built for travel and outdoor shoots rather than submersion.
What warranty comes with it?
SanDisk includes a 5-year limited warranty on the Extreme PRO Portable SSD. Check the product listing for the current terms that apply in your region.
Will it slow down during long file transfers?
The forged aluminum chassis acts as a heatsink specifically to hold higher sustained speeds than plastic-shelled portable drives. Expect the body to feel warm during extended writes, which is the heatsink working as designed.
Do I need software to use it?
No. It works as a standard USB-C external drive. The optional SanDisk Memory Zone app adds file management and automatic space cleanup if you want it.
