Professional reviewers consistently commend the SanDisk Ultra 64GB USB-A flash drive for its solid 130 MB/s read performance, reliable 40 MB/s write speed, and the added value of security and recovery software. They note the longer 5-year warranty as a differentiator, while pointing out the lack of detailed endurance data and the drop in speed on legacy USB 2.0 ports.
Everyday users love the fast read speeds and the generous 64 GB capacity for media and backups, highlighting the convenient capless slide-out design and the usefulness of SecureAccess. Common complaints revolve around slower write speeds, occasional recognition hiccups on older ports, and the fact that formatted usable space is a few gigabytes less than the advertised capacity.
