Crucial X6 1TB
Score: 56/100
SanDisk Portable SSD 1TB
Score: 77/100Rankings
The SanDisk 1 TB Portable SSD combines fast 800 MB/s reads with a rugged IP65-rated aluminum body, making it a solid choice for creators who need durability on the go. While it lacks a USB-C to USB-C cable and built-in encryption, its lightweight design and strong protection stand out.
The Crucial X6 1TB offers an ultra-light, budget-friendly portable SSD with decent everyday performance, but its QLC, DRAM-less design means speeds fall short of the 800 MB/s claim and it lacks hardware encryption.
