Pixara - A USB drive is way too slow to run Poser, but O.K. to keep external runtimes.

spacedragon1234 - I'm %99.9 sure your drive speeds are incorrect.  A SATA HDD is 150MBs/second, which is slightly faster than it's predessesor the Ultra ATA IDE drive, which runs at 133MB/s. 

SATA2 drives run at 200MB/s.

Before the UATA drive IDE drives ran at 66MBs, and 33 MBs before that.

The confusing thing about USB, and USB2 drives is that they are measured in Mb(Not MB.)  Mb means MegaBits, rather than MegaBytes.  A MegaBit is much smaller than a MegaByte.

Although I think your ratio is correct, off hand I beleive SATA is about 10x faster than USB.
