Rank #3 in Best 128GB USB Flash Drives: 10 Ranked, and the Write Speeds the Boxes Hide
SanDisk Ultra Flair 128GB USB 3.0 Flash Drive
Price and rating as shown on Amazon when we collected them. Both change.
The SanDisk Ultra Flair 128GB is the drive in third place in this guide. It is a USB 3.0 stick in a metal casing, listed at £19.00 with a 4.6 out of 5 rating from 194,822 ratings on Amazon, and the bullets promise up to 150MB/s.
That number is the one to look at. The spec sheet lists 150 Megabytes Per Second under Read Speed and 150 MB/s under Write Speed — the same figure in both fields. That is the pattern this guide keeps coming back to: a headline read speed copied straight into the write-speed field. Three other entries on the same sheet are worth reading closely. Hardware Connectivity Technology is given as "USB 3.0 Micro B" on a drive whose Hardware Interface is listed as USB 3.0. The Manufacturer field reads Amplim while the Brand Name field reads SanDisk. And the Colour is listed as Black while the product name says Silver/Black. The rating breakdown shown next to the 4.6 is also worth a second look: 76 five-star and 16 four-star entries out of 100, sitting beside a total of 194,822 ratings. Everything on this page comes from the Amazon listing, not from any testing of our own.
