We compared two 128GB USB-C flash drives with 400MB/s read speeds: the Samsung Type-C and the all-metal SanDisk Ultra Dual Drive Luxe.
What we looked at
Stated speeds, connectors, build and protection, backup software, and price.
The verdict
If you only need a USB-C connector and want a drive stated to be waterproof, shockproof, magnet-resistant, temperature-resistant and X-ray-proof, the Samsung Type-C is the rugged pick, at £27.99. If you want both USB-C and USB-A on one all-metal swivel drive with an app to back up phone photos, for about £6 less, the SanDisk Dual Drive Luxe is the versatile, cheaper choice.
A USB-C stick with 5-fold protection and 400 MB/s reads, but USB-C only and £6 more.
A metal swivel drive with both USB-C and USB-A plus photo backup, for £22.
