Amazon currently has the SanDisk Ultra 400GB Micro SD Card on sale for just $159. That is a great price for a micro SD card that is going to offer a ton of storage for your smartphone or other device. This micro SD card is typically priced at $249, so you're saving $90 or 36-percent, which is nothing to sneeze at here.
This micro SD card from SanDisk boasts 400GB of storage. Currently, that is the largest capacity of any micro SD card on the market. It also has read and write speeds of around 100MB/s which is going to be plenty fast for recording 4K footage and even some 960fps slow-motion - like what you'd find on Samsung and Sony's latest smartphones. That is because those videos use more storage and would typically take longer to write to a SD card. This is also rated A1 for apps support. This means that if you have a smartphone that supports Adoptable Storage (this is largely only Motorola smartphones) you can store apps on the micro SD card and not experience lag, as it is running at the same speed as the internal storage on your smartphone. If you need some more storage for music, movies, photos or something else, then this is definitely the micro SD card to pick up.
This item is also eligible for Amazon Prime's free shipping. Which includes free two-day shipping, and pretty cheap (usually $3.99) next-day shipping if you need it extra fast. If you are not an Amazon Prime member yet, you can sign up for a free trial of Amazon Prime. You'll get 30 days free (if you're a student, you get 6 months), and then it's $119/year (or $59/year for students). Prime members do get a whole lot more than just free shipping though, so be sure to check out the full benefits.
