both Firewire, USB 2.0 AND SCSI are faster then any scanner can scan but not USB 1.1 here are there speeds USB 1.1 OHCI: up to 12 Mbps USB 2.0 EHCI: up to 480 Mbps FireWire (IEEE 1394) OHCI: up to 400 Mbps SCSI IS UP TO 160 MByte/sec All are screaming speeds and the soft ware has a lot to do with how fast one will scan and the different ways a scanner works. I have a Microtek scanmaker X12 SCSI AND USB BUT NEVER EVEN CONCIDERED USING THE USB and for a scanner that only cost $275 I can scan a n 8x10 at 1200 dpi into my computer in just over a min.. Amd I only did that to see how fast it was, at 300 DPI 20-25 seconds. Firewire and USB are the easyest to install, by far good luck Bill Boy > From: Mr645@aol.com > Reply-To: email@example.com > Date: Wed, 29 May 2002 00:24:51 EDT > To: firstname.lastname@example.org > Subject: Re: Epson 1680: USB or Firewire > > > In a message dated 5/28/02 5:31:39 PM, email@example.com writes: > > << Will the SCSI card be better or worse than USB? > Thanks for your advice. >> > > Adding a SCSI card will speed things up by 2 to 4 times.
