Amazon Prime Day is closing today, and these are the best microSD card deals still available; I checked them myself just before publishing the article. While arguably not the most thrilling Prime Day purchase, a cheap microSD card can seriously boost the capacity in your smartphone, but also provide extra storage for a laptop, a DSLR, or any other piece of tech that needs portable storage.

There are a range of cheap microSD cards in the Prime Day sales right now, from trusted manufacturers like Sandisk, Samsung, Silicon Power, Teamgroup and PNY. 

Our recommendation would be to go bigger with your microSD card, unless your device doesn't support those with larger storage capacities, which is why, in 2023, I don't recommend memory cards smaller than 256GB to anyone else as you will end up paying extra (on a per GB basis).

How much storage do you get from a microSD card? Well, let's take a standard 256GB card - which is what most people put into their smartphones. You'll get about 60,000 images on there from a phone with a 12MB selfie camera such as that found in the Galaxy S23, for example. You'll get just over 40 hours of HD video in a card of that size too. So, scale up if you want a 512GB or 1TB 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.

If you need to check out more advice, we have a rundown of the best microSD cards right now, but they're very comparable, so you should be fine with any of the cards we've selected below.
