MR816CSX Lots of dropouts

After switching to the USB interface I can have dropbox AND onedrive syncing while surfing the web with 3 pages open and getting my email with outlook all while recording a stereo 44.1 16 bit audio and NO DROPOUTS. Well, I guess that about sums it up.
Oh well. Anyone in the market for a fully functional MR816CSX in great shape? Just don’t try a PCIe firewire card. It works perfectly with a PCI card.
