How secure is your data? Most computer experts recommend having something they call triple redundancy; in other words, you'd store a picture on your phone, on a memory card, and in the cloud. Most of us don't do that, myself included, but you can get your hands on inexpensive memory cards and external storage drives in this one day sale in honor of World Backup Day. Save as much as 70% off on items like this SanDisk 1TB Memory Card, now only $100 (down from $300).

SanDisk 1TB Extreme microSDXC Memory Card

$100$300Save $200

With a full terabyte of storage (that's 1024 gigabytes), this card is ideal for use in a camera or even with game consoles like the Nintendo Switch or Steam Deck.

MicroSD memory cards can be pricy, especially those with high storage capacities. This is a great chance to score a full terabyte of memory for a third of the price as normal. If you need extra memory in your phone or you want to store even more games on a Nintendo Switch or Steam Deck, this 1TB memory card is fast enough to handle all of your data at bargain prices.

One user said, "I started running out of space on my 400GB card on my Nintendo Switch and decided to go all the way for max capacity when I caught this card for its lowest price ever. Well worth picking up at sale price, and the speed has been excellent for the purpose."

But the sales don't stop there! There are even more memory cards for sale:

If you don't need a memory card, but you want external storage for your computer, there are plenty of options in that category, too. For reference, an SSD (or solid-state drive) is a faster, more secure version of a traditional hard drive. It's where all of your information is stored on your computer.

SanDisk 2TB Extreme Pro Portable SSD

$175$230Save $55

SanDisk is one of the most highly-regarded brands, with proven reliability and longevity in their drives. Pair that with the sturdy case on this portable SSD and you have a winning combination.

$175 at Amazon

This rugged drive is rated to survive drops from two meters in height and boasts some water resistance to boot. It's a great accessory to keep in your work bag and gives you an easy way to quickly store large files without taking up too much memory on your computer itself.

"This device will save your bacon," one reviewer said. "SanDisk 1TB Extreme Pro Portable SSD is probably the single best 'electronic' investment I've ever made! I've been totally emersed in technology for my entire life... I'm familiar with a wide variety of support equipment and, frankly, this little backup device is at the pinnacle of the bunch. It's totally user-friendly and much (MUCH!) faster than a USB 'thumb drive' or SDRAM card. I 'archived' over 27,000 files (315GBytes) in less than 20 minutes without a glitch. Any PC user who's concerned about their data (and everyone should be!) is at risk if they're not regularly backing up critical files. My money's on this device!"
