SAVE $52: As of July 10, Prime members can grab the 1TB SanDisk Extreme Portable SSD for just $77.99, down from $129.99 — a 40% discount.

Whether you're managing video footage on the go or just need a more reliable way to back up your files, Prime Day has delivered a portable storage gem. The SanDisk 1TB Extreme Portable SSD is down to just $77.99, its lowest price this year according to trackers like camelcamelcamel — but only for Amazon Prime members.

Don’t be fooled by its slim profile. This little beast promises to deliver read speeds of up to 1050MB/s and write speeds of up to 1000MB/s, thanks to its USB 3.2 Gen 2 interface and NVMe solid-state performance. Essentially, this means you can move large files like 4K video or photo libraries in seconds, not minutes.

Designed with durability in mind, the SanDisk Extreme Portable SSD features IP65-rated water and dust resistance, and can survive drops from up to three meters. Whether it’s clipped to a backpack or stuffed into a gear bag, this drive is built to last and keep its contents safe. That’s why it gets bonus points for the carabiner loop, which adds both utility and peace of mind.

Security-wise, the drive includes 256-bit AES hardware encryption and password protection, which is helpful if you're keeping sensitive files on the go. It also works seamlessly with the SanDisk Memory Zone app, which makes file management across devices dead simple.

With over 79,000 five-star reviews on its Amazon page so far, and a spot near the top of Amazon’s best-seller list, this external SSD is clearly a fan favourite — and this $52 discount makes it easier than ever to grab one for yourself. Just be sure to sign in with your Prime account to snag the deal before it’s gone.
