I have a new Iomega 4TB NAS at work which I'm trying to use.
I have  it connected to a switch and want to use it for backup. It is very slow to transfer data. I CANNOT connect directly to it with USB but only through CAT5.
Right now I've tried connecting the NAS directly into my server using a crossover cat5e. At this point I really don't know what else I need to do. How can i communicate with this crossover cable and make the NAS quicker to respond.

Eliminating the switch should have minimal effect, assuming that the switch does not have problems.

How slow is the data transfer?  Have you tried a simple xcopy of a large file?

I ran into serious speed problem with a NAS device once that had to do with Opportunistic File Locking.  You might check to see if that is something that can be disabled.  Of course, investigate the potential problems with that.  I ended up making two shares, one for general use with OFL disabled and one for a specific application with OFL enabled.  The application's speed wasn't such an issue so this worked well.

When running the Xcopy, take a look at the networking tab in Task Manager.  It would be informative to know what that looks like.  Does it seem to hit a certain speed and then go no faster?  If so, what is that speed?

To give you an example I tried transfering 48GB of Data and it said it was going to take 5 hours.
So after 30 minutes i simply canceled it. I will try running the Xcopy tomorrow I will let you know what happens. Thanks
