SanDisk's coin-sized 512GB ExtremeFit flash drive doubles storage for $99
Tiny USB-C drive delivers 400MB/s read speeds and 512GB for $99
SanDisk's ExtremeFit USB-C flash drive is one of the smallest external storage devices on the market — roughly the size of a wireless mouse receiver — yet it packs up to 512GB of capacity. Currently on sale for $99 (17% off the $119 regular price) during Amazon's Prime Day event ending June 26, 2026, it offers a practical way to double a laptop's built-in storage without adding bulk. The drive delivers read speeds up to 400 MB/s and requires no software or formatting; just plug it into any USB-C port and it works immediately.
Compatible with PCs, Macs, Chromebooks, and iPads, the ExtremeFit is aimed at content creators and professionals who frequently move large files such as 4K video, high-resolution images, and complex renders. The 512GB configuration can store thousands of such files or hundreds of hours of full-length movies. However, its tiny size makes it easy to misplace, so keeping it plugged into a laptop's USB-C port or stored with other tech accessories is recommended. ZDNET rated the deal 3/5, noting the discount is modest but the product itself delivers solid value for portable storage needs.
