Best Shock-Resistant Hard Drives for Mac iMore 2020

Sometimes it's best not to store absolutely everything right on your Mac. For one, it clutters things up, and unless you're willing to upgrade your SSD, which you can't in the latest MacBook Pros, you're going to fill up way too fast. Grab one of these hard drives and know that a shock-resistant enclosure protects your data. Our favorite is the CalDigit Tuff USB-C 2TB for its proven ability to withstand harsh situations.

Note: Always keep in mind that just because a hard drive is shock-resistant, that does not mean it is shock-proof. Shock-resistant hard drives can still suffer damage on impact.
