512GB is a staggering amount of storage, especially when compared to the “roomy” 40GB hard drive I used to have on my old PC. Today you can pick up a 512GB card smaller than your thumbnail for a great price. Amazon has a Silicon Power 512GB MicroSD card for just $29.97.
This MicroSD card is perfect for expanding the storage of an Android phone, Steam Deck, or Nintendo Switch. With a Class 10/V30 speed rating, it should handle write speeds of up to 30MB/s, which will even be good enough for all but the most intense video recordings, so it’s also a good match for a DSLR or mirrorless camera with the included full-sized SD card adapter.
Half a terabyte is enough to hold about 113 hours of video recordings or 150,000 photos (according to the 3MB photo I just took with my phone). It’s enough to hold the massive Baldur’s Gate III PC game three times over.
This price is well below even the sale price of similar cards from brands like SanDisk and it looks like it’s Amazon’s regular price, so I wouldn’t expect it to go out of stock any time soon.
