microSD cards going cheap is a Prime Day staple. While not the most thrilling Prime Day purchase, a cheap microSD card can seriously boost the capacity in your smartphone, or provide extra storage for a laptop, a DSLR, or any other piece of tech that needs portable storage.

Most are cutting between 20-60% off prices, so you can pick up some serious storage for your money.

How much storage do you get from a microSD card? Well, let’s take a standard 128GB card – which is what most people put into their smartphones. You’ll get about 30,000 images on there from a phone with a 12MB camera, which is what you’ll find in the Galaxy S20, for example. You’ll get just over 20 hours of HD video in a card of that size too. So, scale up if you want a 256GB or 512GB card.
Almost all these cheap microSD cards come with a free SD card converter as standard, so they’ll slot into most DSLRs and mirrorless cameras. This gives you the flexibility to remove the microSD element and slot it into your phone, to copy or store images from a camera.
