There’s nothing quite as frustrating as running out of storage, and there’s no such thing as too much of it. For Prime Day, Amazon is discounting a whole fleet of SD and microSD cards and getting a bigger one for whatever gadget will take one is a no-brainer upgrade.
The standout deal is a 128GB Sandisk Extreme microSD for just $20 ($49 off), complete with with an SD adapter. Or, if you want even more breathing room you can pick up a 256GB microSD for $30 ($13 off), a 512GB microSD for $99 ($80 off), or a truly overkill 1TB microSD for $340 ($109 off).
