Solved Question about data transfer rates through USB ports

Specs: Windows 7 Home Premium, 2.399 GHz / 5814 MB
I have a laptop with a couple of 2.0 USB ports. I have been transferring data to another computer that also has 2.0 USB ports. I've been doing it with two different methods. One, I 've been moving it onto an external 1Tb AC powered Western Digital drive. Second method is moving it onto a thumb drive that is also USB 2.0 The rate onto the 1Tb Western digital drive is way faster, almost five times as fast. I'm wondering if even though both support only as high as USB 2.0 allows, will some 2.0 thumb drives allow better transfer rates, or is it just that moving data onto the external drive with a mounted disk will always provide the higher rate. I'd prefer to use a thumb drive as it's just more portable. Will some 2.0 thumb drives provide higher rates than others? I'm thinking not, but considered trying another perhaps better quality 2.0 thumb drive just to see if it would give a higher rate. Or is that redundant?

✔ Best Answer
It has little to do with the transfer speed of USB and a lot to do with the read/write speed of a hard disk compared to the flash memory in a thumb drive. Flash memory will always be slower than a hard disk.

The performance of flash drives varies widely. The maximum speed of USB 2.0 is about 35 MB/Sec but few flash drives will reach that. Many are much less.
