This drive uses a rotating cap design that protects both USB-C and USB-A connectors without removable parts. The all-metal body keeps the drive compact while providing durability. SanDisk has updated this model with improved performance over earlier versions, though it still uses a USB 3.2 Gen 1 interface that limits maximum speeds to 5Gbps.
Key specs and capacities
The Ultra Dual Luxe comes in 32GB through 1TB capacities with a USB 3.2 Gen 1 interface rated for 5Gbps bandwidth. It measures 44.5mm x 12.2mm x 8.6mm and weighs only 17 grams, making it noticeably smaller than competing dual connector drives. The drive features a metal construction with a rotating cap mechanism that eliminates the need for removable caps. SanDisk offers this model in silver only.
Real world performance and speed
SanDisk rates the Ultra Dual Luxe at up to 400 MB/s for read operations. The 5Gbps USB 3.2 Gen 1 interface caps theoretical maximum speeds at 625 MB/s, so the drive operates well within this limit. You’ll transfer files significantly slower than drives using USB 3.2 Gen 2 interfaces.
Best use cases and device compatibility
This drive works best for basic file transfers between USB-C and USB-A devices where size matters more than speed. You’ll appreciate the compact design when moving documents, music libraries, and standard definition videos.
Pros, cons, and reliability notes
Pros: Extremely compact, rotating cap prevents loss, lightweight, clean metal design. Cons: Limited to 5Gbps speeds, runs hot during extended transfers. SanDisk backs the drive with a five-year warranty.
