USB flash drive deals FAQs

What capacity do I need in a USB flash drive?

This is a question that you need to answer yourself because it really depends on what you plan to use it for. If you’re only moving work documents around, a small capacity like 64GB will be fine. If you want to use a flash drive for backing up photos, videos, games, and other big files, then you might want to go 512GB or larger.

What features should I prioritize when choosing a USB flash drive?

First of all, our recommendation is to look at the flash drive’s transfer speeds. To ensure you get fast read/write speeds, you should get a USB 3.0 or above. USB 2.x drives are sorely outdated.

Then, you have to make sure the flash drive can survive living in your pocket, getting crushed by your laptop, falling through your fingers, and so on. Aluminum casings will offer better protection in such cases.

If the flash drive offers 128-bit AES encryption or better, your data will also have some extra protection in case you lose it, as the drive will be inaccessible and block out others from reading your data.

How did we find the best USB flash drive Prime Day deals?

Finding great deals can be difficult because not all discounts are worth covering. When looking for good Prime Day deals, we compare the prices on Amazon with the regular retail price and check pricing history to see if there have been any changes lately and that the price drops are truly noteworthy. We also check product reviews to see if they’re reliable in the long run and live up to their promises.
