The Crucial MX500 4TB is the objective winner of this comparison, securing more spec victories than the Crucial MX500 500GB. The most impactful advantage offered by the larger drive is its capacity, which is 700% better than the smaller model. This significant increase in storage space provides a substantial benefit for users requiring extensive room for files, media, or applications, outweighing the minor spec advantages held by the lower-capacity version.

Choose the Crucial MX500 4TB if your primary requirement is maximum storage volume for large datasets or extensive libraries. Conversely, opt for the Crucial MX500 500GB if your priority is the MSRP, which is 76% better than the larger drive. This smaller model is the logical selection for budget-conscious users who do not need the massive capacity provided by the 4TB version and prefer the cost efficiency of the lower-capacity unit.
