Hey Jack,
My name is Joe. I too felt like an ass asking my first question, but I've yet had a Negative or wiseass answer sent my way!!! Ever! So don't sweat that , Everyone here like to help people, they love to share their knowledge!!!
OK So onwards. It's good that you bought a 4 bay NAS Enclosure, because eventually. that 1.5 TB will grow on you ...Trust Me!!!
1 Question, how long ago did you buy the Netgear Nas? The reason I'm asking is, is it past 30 days so you can return it.
I personally just bought a Synology DS 713+ 2 Bay NAS Enclosue, which has the capability to link another 5 Bay unit for expansion.
The reason I went wiwth the Synology, is because the OS which is called DSM Is the Best on the market! Here is 2 links for you tolook at, so you can c what this 2 bay Nas can do. Check out the specs on •VMware® with VAAI support, Citrix®, Microsoft® Hyper-V® compliant
If your set on a 4 -bay enclosure, go to Amazon n c heck them out. Compare the Synology and the Netgear enclosures and youll c the Syn are just a better product..because of the OS...in my opinion.
Check out what the OS can Do. It's called DSM ( Disc Station Manager). Her is a link to c how easy it is to use.

As for Free Nas.It's Really good, but not much in the support catagory. Here is a link on the top 5 NAS
http://lifehacker.com/5968677/five-best-nas-enclosures Thewr are soooooooo many opinions out there, All I can tell you is that Synology's OS is Rated #1
Best of luck!!! I know I didn't really answer your question, and Netgear also make a Fine NAS, don't get me wrong, I've heard their X-Raid is awesome!
I just didn't want you to b afraid to ask!!! Someone will get back to you. If no one does, try a difffernt forumn
Best of Luck Jack, and make sure you get an expert in Nas to help you out, I just started with it........But this Synology DS713+ Rocks!!!

One other thing Jack, if you ca still return it, check out the reviews on how easy this is to setup.
You also said you only han 1.5 TB's your working with now, well this unit will do it, and it is expandale with a 2 bay unit or a 5 bay unit. But I want you to c how easy it was for all the peeps that bought this Synology DS 713+. Check out the reviews on All the people that bought this unit!

just copy and paste that link n you'll c how easy it is to setup.
If it's too late too return it, get Netgear on the phone and have them get u str8, they should if your spending that much money. Even if you can exchange it and want a 4 bay unit Check out the DS 412+ it runs on the DSM 4.0 os and it's awesome!!! Qnap's OS just comes as close to Synology's DSM 4.0. So if you can return it, do some more research.
Best of Luck
Joe
