Working outdoors or in extreme conditions? The SanDisk Extreme Portable is one of the best external SSDs we ever tested— and it’s $250 off

I’ve found a great deal on my favorite rugged portable SSD that's a serious must-buy for business travelers and on-the-go creators. The Sandisk Extreme Portable 4TB SSD is now $570 (was $805) at Best Buy.

If you work on the go, travel often, or shoot outdoors, you'll know how your gear can take a beating. Tossing 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 boasts an IP65 rating that makes it dust and water resistant. Add in a huge $235 discount and you have a storage unit that we called "hands-down one of the best external SSDs (rugged or not) on the market" in our review.
