Our Take

Best for: Photographers, videographers, and frequent travelers needing fast, durable storage.

The SanDisk Extreme Portable SSD is a high-capacity external drive built for people who move around a lot. It combines 4TB of space with fast NVMe performance, claiming speeds up to 1050MB/s. That means transferring large photo sets or video projects won't hold you up. What really stands out is its rugged design. It's now rated IP65 for water and dust resistance and can survive drops from up to 3 meters, which is a practical upgrade from older models. The built-in carabiner loop is a simple but useful touch for attaching it to a bag. The drive includes 256-bit AES hardware encryption, which you can set up with a password to protect sensitive files. 2 Gen 2 (USB-C) port on your computer; otherwise, you won't get the full performance. At this sale price, it's a capable and durable option, though the cost for 4TB of SSD storage remains significant.

Price Analysis

At $449.99, this is an 8% discount off the listed original price. The 90-day average price is $451.55, so this sale is slightly below that recent norm. However, the 180-day average was notably lower at $375.86, suggesting this isn't a deep historical discount. It's a fair current price, but not a standout low.
