Ummmm... Guys.... I think you may have lost your audience. Your sure lost me.
Sandeep's post with the links "This one good, this one better" was really helpful. But, I must question the actual utility of some of the other suggestions.
For example: we have a Gigabit switch. My client machine has the option of going hardwired or wireless. Obviously, hardwired is oodles faster. But, you know what? I can't really tell the difference in day to day operations. Most of my time is taken in thinking what I want to say, what that lab test means, whether those numb feet are from diabetes or B12 deficiency, and all those zillions of medical decisions that we do all the time. The network speed, or the speed of the hard drive is so far from the limiting factor of what time I go home each day that it is not even a consideration.
The variability of wireless speeds is pretty large. Do you really waiting 30 seconds for a chart to open when on WiFi. There was a pretty large uproar with a 10 second delay for the prescription writer. Staff definitely notices a difference when using WiFi. You also have to take into account the network load. If you have 2-3 computers, 100 Mbit is pretty good. When you have 10, gigabit tends to be more useful with everyone accessing files and whatnot. Also, you have to take into account the location of your files. If everything is one place like a server setup. Its bandwith can easily become saturated. For instance, I have folder redirection enabled on my server so no files are stored on the workstations. Everything is on the network. You can see how my network is my new bottleneck.
The other thing is maintenance. Lots of things can go wrong with wireless. Bad range, dropped connections, losing connection to the database. These issues are pretty much non-existent for wired. Pretty simple A to B Operation.
I don't if you've used an SSD before, but once you do, it's pretty hard to go back to a regular hard drive. Multitasking works much better. Everything is more fluid. There are no moving parts in an SSD, so mechanical failure isn't possible. So you get the reliability aspect. I think there's even a guy on youtube jumping on a trampoline with 20 SSDs plugged in. There's no delay when opening or closing programs. I know some doctors leave computers on all the time because they take too long to boot.
What it boils down too is the user's ability. If he or she benefits from the speed, then go ahead and get them. What you could do is put an SSD on your personal computer and see how you like it before upgrading all of the computers. Considering I have 40 windows open now and using 8GB of RAM, constantly opening and closing programs. It's worth it for me. (Extreme case) Even if you're not that crazy. Everyone enjoys a responsive computer. Getting an SSD was the best upgrade in my opinion. Everyone I know who has used them start to hate hard drives.
