I found a great deal on my favorite rugged portable SSD that’s a must-buy for business travelers and creators on the go. The Sandisk Extreme Portable 4TB SSD is now $570 (was $805) at Best Buy.
If you work on the go, travel frequently, or photograph outdoors, you know how your equipment can take a beating. Stuffing a drive into a backpack with cameras, cables, and laptops isn’t exactly gentle.
That’s why I like this storage solution: it’s high capacity, with a robust and durable design that has an IP65 rating that makes it dust and water resistant. Add in a whopping $235 discount and you have a storage drive that we called “certainly one of the best external SSDs (rugged or not) on the market” in our review.
The best SSD offer of the moment
In our review of the 1TB model, we said: “When used with a USB Type-C cable, the SanDisk Extreme rises above the competition with some stellar numbers. The design and form factor are perfect, and while we have a reservation regarding the included cable, you can’t go wrong at this price.”
With 4TB of space, you have room for huge photo libraries, 4K video projects, game files, and full system backups. For creatives and professionals working with large assets, that capability is a huge advantage.
SanDisk Extreme Portable offers read speeds of up to 1050 MB/s and write speeds of up to 1000 MB/s over USB-C with USB 3.1 Gen2. That means fast transfers, faster edits straight from the drive, and less waiting time.
It’s an external NVMe SSD, so you get solid-state speed in a compact form factor that fits in your pocket. At just 2.4 oz, it barely adds any weight to your setup.
The robust design is obviously a big plus and means it’s designed to handle life away from a desk, whether working from a coffee shop, editing on-site or backing up files in a hotel room.
The SSD also supports 256-bit AES hardware encryption, giving you added peace of mind if you’re carrying sensitive personal or work files.
Plug it in via USB-C and you’ll get power directly from your device, so you won’t have to worry about any additional adapters.
It also comes with a 5-year warranty for added peace of mind.
For just $570, you get 4TB of fast, portable, and durable storage for much less than usual.
