I'm glad that everything works for you now. The difference in size is that you are unaware of the difference between a gigabyte and a gibibyte..
A 2Terabyte harddisk is NOT 2000 gigabyte in size but 2000 gibibyte. When you connect a 2TB drive you have about 1.83 left (if I recall correctly). If you do that 5x, you'll notice that you already lost 1 TB due to incorrect assumption that your drive is 2TB. (and I do agree that 2TB should be 2000 Gigabyte)...
I have no clue how much real space there is on a 3TB drive, assume it will be something around 2.7 TB, and you have 4 drives cause you lose one in your raid5 array... so 4x2.7 is 10.8 TB...
The reason i said you will have a problem in the future with the diskstation is not because of the product. It's a great machine. The problem you will encounter is that now your interest in this matter has gotten your attention to other option that are more versatile. You probably still wonder how ZFS would be, and how FreeNAS would perform, if it could run on your old hardware, if it would save money to have various programs (SabNZBD, sickbeard, couchpotato, headphones, transmission, virtualbox, phpMyAdmin, MySQL, etc etc) running on the same machine that holds your storage, so that you don't need to have multiple machines powered on 24/7, or adding a drive which is obviously impossible on a 5-bay machine...
The diskstation is a great great machine. I have read about them a lot and lots of people are really happy with it, and it also allows for some other programs to run in the background, just not to the extend of a machine running linux or freebsd. To put things into perspective, you have bough a computer based on a mini-itx board with a very slow cpu, no graphics card, little memory, no storage devices, for 800 USD... for that kind of money you could have assembled quite a phat machine...
