SanDisk Extreme Portable SSD V3 4TB External SSD, USB 3.2 Gen 2x2 USB-C, up to 2000MB/s Read, IP65, Black

The SanDisk Extreme Portable SSD V3 4TB (SDSSDE70-4T00-G25) is a pocket-size external SSD with a USB 3.2 Gen 2x2 (20Gbps) USB-C interface and up to 2000MB/s sequential read, built for photographers, video editors and anyone who moves large projects between computers and needs them to survive a bag, a shoot or a site visit.

This is the third generation of the familiar Extreme portable drive with the orange carabiner loop. Compared with the earlier V2 (SDSSDE61, up to 1050MB/s over USB 3.2 Gen 2), the V3 roughly doubles the published read speed — but only when it is connected to a port that actually supports USB 3.2 Gen 2x2. On other ports it still works, at the speed of that port. The 4TB version is offered in Black only.

• SanDisk Extreme Portable SSD V3, 4TB, Black
• USB-C to USB-C cable
• Quick Install and Warranty Guide
• No USB-A cable or adapter is included

• On a PC or laptop with a USB 3.2 Gen 2x2 (20Gbps) USB-C port you get the full speed class: up to 2000MB/s read and up to 1700MB/s write — SanDisk quotes moving about 1,000 high-resolution photos in under 60 seconds.
• On a standard USB 3.2 Gen 2 (10Gbps) USB-C port, including Macs, the drive runs at that port's speed, which is still several times faster than a portable hard drive.
• 4TB is enough to keep a full season of RAW photos, several 4K video projects or a complete system backup on one drive you can carry in a pocket.
• IP65 means it is dust-tight and resists water jets (tested at 30 kPa for 3 minutes) — rain on a shoot or a spilled drink is covered, submersion is not. Dry it before connecting.
• Drop protection up to 3 metres and the carabiner loop make it suitable for field work, travel and site visits rather than only desk use.
• Password protection with 256-bit AES hardware encryption keeps the data unreadable if the drive is lost; this requires the SanDisk software on Windows or macOS.

• It will not reach 2000MB/s on a Mac, on a Thunderbolt-only port or on any USB-C port that is not USB 3.2 Gen 2x2 — the speed drops to what that port supports.
• It will not connect to a USB-A port with the included cable — you need a separate USB-C to USB-A cable or adapter, and speed is then limited to that port (USB 3.2 Gen 1/Gen 2 or slower).
• It is not an internal drive and cannot be fitted in a laptop or desktop M.2 or SATA bay — for that see our internal SSDs.
• It is not waterproof for submersion: IP65 covers dust and water jets, not immersion.
• Hardware encryption with password does not work on its own on every device — it needs the SanDisk software on a supported Windows or macOS computer; on phones and tablets the drive works as normal storage.
