Rank #2 in Best 64GB USB Flash Drive 2026: 9 Ranked, and Three Spec Sheets That Contradict Themselves
SanDisk Ultra Flair 64GB USB 3.0 Flash Drive
Price and rating as shown on Amazon when we collected them. Both change.
The SanDisk Ultra Flair 64 GB is the number 2 entry in this guide. It is a USB 3.0 Type-A flash drive in a black metal casing, listed at £15.19, with a rating of 4.6 out of 5 from 194,822 ratings. The listing describes transferring a full-length movie in under 30 seconds and claims transfers up to 15 times faster than standard USB 2.0 drives.
The finding for this one is in its own spec table. Read Speed is given as 150 Megabytes Per Second and Write Speed is given as 150 MB/s — the same number in both fields. On a USB flash drive, writing happens at a lower rate than reading; identical figures in the two rows suggest the write field was filled in with the read figure rather than measured. This model is one of three in the guide where the two numbers match exactly, so it is the pattern rather than a single slip. Everything on this page is taken from the Amazon listing for this drive, not from any test of our own.
