This microSD card is a perfect add-on for a smartphone, tablet, or camera. It supports read/write speeds of 170/90 MB/s, making it fast enough to record 4K UHD video and to run apps on certain devices.

Fewer devices have microSD card slots than they used to, but some of the best Windows tablets have them. For example, Microsoft's new Surface Go 3 features a microSD card slot. The Surface Pro 8 does not have a microSD slot. You'll need to double-check if your device has a dedicated microSD slot or be willing to use a dongle.

The current discount on the SanDisk Extreme PLUS through Best Buy only lasts until the end of the day, October 28, 2021. If you miss out on this deal, you may have to wait until Black Friday to find it for a similar price.
