We’ve already seen some awesome smartphone deals during Prime Day 2019, but if you’re happy with your current phone and just want to give it some more storage, we’ve got you covered there, too.

Amazon is now running a big Prime Day sale on Sandisk and Western Digital storage products. Included are deals on internal and external hard drives, flash drives, NVMe SSDs, and more. Most interesting to us smartphone and tablet owners, though, are the microSD card deals:

• SanDisk Extreme 1TB microSD card for $340.82
• SanDisk Extreme 512GB microSD card for $135.99
• SanDisk Extreme 256GB microSD card for $42.99
• SanDisk Extreme 128GB microSD card for $19.99
• SanDisk Ultra 512GB microSD card for $99.99
• SanDisk Ultra 400GB microSD card for $44.99
• SanDisk Ultra 256GB microSD card for $29.99

These are some of the best deals we’ve ever seen on these Sandisk Microsd Cards, including the massive 1TB model. The big difference between the Extreme and Ultra models is the faster read and write speeds, which will come in handy if you record a lot of 4K video.

Because these are Prime Day deals, you’ll need to be an Amazon Prime member to get them. The good news is that if you’re not already a Prime member, you can sign up for a free 30-day trial and get the discounts right now.

SanDisk’s microSD cards are a great way to add more storage to your smartphone, tablet, or gaming console, letting you carry more music, videos, or games everywhere you go. If you’re running out of storage on your mobile device, these SanDisk deals are definitely worth checking out.
