Our take on the SanDisk Extreme Portable 4TB USB-C NVMe SSD

The SanDisk Extreme Portable is a pocket-sized external NVMe SSD rated at 1050 MB/s read and 1000 MB/s write over USB 3.2 Gen 2. It ships with both USB-C and USB-A cables, so it works with modern laptops, phones and older ports without an adapter. The 4TB model holds a large photo or video library in a shell small enough to clip to a bag. It is faster than SATA-based portables and spinning external drives, but it is not a rugged waterproof drive and it slows down on USB 3.0 or USB 2.0 ports.

  • Aluminum body with a rubberized edge and a carabiner loop
  • Works with Windows, macOS, Android and iPadOS out of the box
Cons
  • Falls to USB 3.0 or USB 2.0 speeds on older ports

Questions and answers

Is it fast enough to edit video directly from the drive?
Yes for most 4K footage. It reads near 1050 MB/s on a USB 3.2 Gen 2 port, which handles typical editing workloads. Very high-bitrate 8K or multicam projects are better on an internal drive.
Does it work with a phone or tablet?
Yes. It connects over USB-C to Android phones, iPads and many newer iPhones, and files can be moved with the built-in file apps. Formatting may be needed for some devices.
Is it waterproof?
No. It is rated for dust and drops, not water immersion. Keep it dry and use a case in wet conditions.
What is in the box?
The drive, a USB-C cable and a USB-A cable. No power adapter is needed because it draws power from the port.
How does it compare with a portable hard drive?
It is much faster and far more resistant to shocks because there are no moving parts. A hard drive still offers more capacity for the same outlay at the very top end.
Can I use it with both Windows and Mac?
Yes, but pick the format first. exFAT works on both; APFS or NTFS lock you to one platform without extra software.
