Professional reviewers commend the S5 series for its durable COB construction, solid 140 MB/s read performance and the confidence provided by a lifetime warranty, while noting the lack of published write-speed figures.
Everyday users appreciate the quick read speeds, tiny footprint, and rugged feel, but mention slower write speeds, occasional heat during heavy transfers, and a slight loss of usable capacity after formatting.
