Few components have changed how I use my computer as much as an SSD has. A few years ago, I finally got a PC with an SSD as the boot drive and now my machine boots within seconds every single time. Soon after that, I switched to an external SSD that I carry with me. I’m always on the lookout for great deals on both these products, since SSDs tend to be a bit pricy compared to traditional hard drives. In my research, these are the best deals on internal and external SSDs for October Prime Day.

4TB Samsung T7 Shield external SSD

The Samsung T7 Shield is one of the most popular external SSDs in the market and it’s over half off for Prime Day. You can get the 4TB Samsung T7 Shield for $237.49, down from $499.99.

If you’re looking for a good deal on a rugged external SSD, the Samsung T9 2TB may be the right one for you. This one is down to $170.99, which is 43% off its list price of $299.99.

8TB SanDisk Desk Drive external SSD

The 8TB SanDisk Desk Drive is an option to vastly expand the storage of your laptop or desktop PC. This drive will have to be plugged in because it needs AC power, which means you can’t easily travel with it. However, it’s a good choice if you want a fast drive to back up your data. You can get it for $503.49, which is 28% off its listing price of $699.99.
