If you have any old hard drives or SSDs lying around, you can give them a second lease on life with an inexpensive enclosure, which turns them into always-useful external storage devices.
3.5" and 2.5" options from Aukey are both on sale today, the latter of which runs over USB-C and includes a C-to-C cable, making it ideal for use with modern laptops. Just make sure to note the promo codes.
