SanDisk Extreme 400GB microSD card

The fastest speed class microSD card available from SanDisk is now at its lowest price, but this deal is good for just one day only.

$85.99 $123.49 $38 off

The microSD card has read speeds up to 160 MB/s and write speeds up to 90 MB/s. You'll be able to transfer even high-res images and 4K videos without much delay, and the card is fast enough to keep up even with fast shooting. This is a UHS Class 3 card (Ultra High Speed) with an A2 rating. Most cards we post deals on are rated A1 and Class 10. This is better in both regards and is generally reserved for professionals. The card is designed to resist extreme temperatures, water, shock, and X-rays. It has 4.4 stars based on 673 reviews. Many devices cannot handle a microSD card this large, so make sure your device is compatible before purchasing.

If you don't need the outright insane performance of the SanDisk Extreme, you could also go for the SanDisk Ultra 400GB card. It's not quite as powerful but it's down to just $65.99 right now.
