USB 3.0 data transfers should be up to 10 times faster than USB 2.0 — and 2.0 should be almost 10 times faster than USB 1.0. But many factors can cause your USB connections to limp along at a fraction of their expected speeds.
Here’s how to check your USB system’s performance to verify that it’s running at its full speed — and what to do if it’s not.
Subtle problems can slow USB by up to 90 percent
When was the last time you checked your USB system’s performance? Never?
When Windows Secrets Reader W. Ross Stone measured his USB connections, he discovered that his 3.0 devices were poking along at 2.0 speeds.
Noticing that backups to an external drive took much longer than expected, he used laborious, manual throughput testing to prove that the USB connection was the bottleneck.
He asked whether there’s an easier and faster way to tell whether a USB connection is operating at or close to its rated speeds.
Indeed, there is.
