USB Flash Drives - Temporary Internet Files
I currently use Internet Explorer, and have considered moving my Temporary Internet Files folder location to my USB flash drive. I've heard that the benefits of doing this can decrease hard disk workload, thus improving browser and system performance.
My question is...
What are the pros & cons of using this method, in a security-minded sense?
I know that this would add an extra layer of privacy, as internet data is not written to the hard drive, right?
What other pros are there? Are there any cons?
