Currently, my office uses a router and connected to the router are a 100Mbit switch and 4 other computers. The 100Mbit switch has 5 computers connected to it. Right now, all the computers are loading a 100MB file (for quickbooks) and saving it to a computer (not server) holding this file. The computer with the file uses RAID1. This is pretty vague, I know. I'm just trying to get some ideas for now. I'll be looking at all the hardware for the machines and I'll add the information once I get it. Here are some ideas I had: - Upgrade to a gigabit network (although if it is a harddrive speed issue, the extra network speed won't help) - Move the file to a file server so it isn't on a workstation that is being used. I've heard about some external network harddrives, but I can't seem to find any information about them. Anyone heard of them? Thanks in advance. EDIT: What tools should I use to benchmark the network speed and harddrive speed of the workstations? I'm looking for something small that fits on a disk or something.
