SanDisk has unveiled the Extreme Fit, a tiny 1TB USB-C flash drive designed to blend right into your laptop and stay there. Marketed as a “leave-in design,” it’s a storage solution meant to be as unobtrusive as possible, perfect for ultrabook users or anyone who doesn’t want a bulky drive dangling from their port.

SanDisk Extreme Fit offers storage without the bulk

Roughly the size of a wireless mouse dongle, the Extreme Fit features an L-shaped USB-C connector that slots vertically into your laptop. The result? It barely juts out, sitting flush enough to avoid snags while still leaving just enough clearance so your laptop lid doesn’t press against it when closed.

It’s not meant for rugged removal and reinsertion, though. USB-C isn’t known for its physical durability under stress, so if you’re always tossing your laptop into a backpack, some care is still advised.

SanDisk’s range of sizes with one clear standout

The Extreme Fit comes in multiple storage options:

• 64GB ($15.99)
• 128GB
• 256GB
• 512GB
• 1TB ($117.99)

Though all sizes use USB 3.2 Gen 1, speeds vary slightly. The 1TB version hits up to 400MB/s, while the 64GB model tops out at 300MB/s. It’s not the fastest drive on the market, but speed isn’t really the headline here it’s size and convenience.

Practical for everyday use, but not indestructible

This is the kind of drive you use to expand your storage without expanding your setup. It’s ideal for keeping media libraries, backups, or large files on hand without the drag of external drives or cloud syncing.

That said, its small footprint doesn’t make it indestructible. The connector could still snap under pressure, so “leave-in” doesn’t mean “care-free.”

A micro storage upgrade for modern laptops from SanDisk

The SanDisk Extreme Fit USB-C SSD is now available in the US and other regions, with the 1TB version offering one of the most compact ways to expand your laptop’s storage. If you’ve ever wanted an invisible upgrade, this might be the most practical one yet.
