Raid 5/6 Controller card suggestion help.

[Banditfromhell]

I will state that I know the 'principles' of how RAID works. I don't know what type of cards brand wise, what to look for, ECC, internal on board battery backups etc.

What I am wanting to do is to build my first array. My purpose is to convert my 2000+? DVD collection onto hdd. I am not looking for anything blazing fast, just more for storage and stability, and reliability. Doing at DVD9 to 4.7gb ISO format, i estimated my needs at about 10TB. [I don't know yet if i am just going to convert it just a h264 format and then stream. My main idea was to do a backup].

So I need a suggestion on what type of RAID card and HDD types.

1) I was hoping to have the ability with a controller card to have RAID 6 preferably.

2) Nothing that would require an 'enterprise' type drive. I was reading in threads and post how there was possible drive spin downs which would cause the array to go haywire.

3) Expandable to the point of where if I just wanted to plug in say a few extra drives and add space to the array it would be easily done.

4) Good OS support. I am not familiar with any *nix distros. So meaning preferably windows based.

5) I know from what I was understanding I want to have a battery backup. Even tho I will have a UPS on the server.

Budget: I don't know kinda probing around for the card first then to figure out the drives later on.

Wanting a storage array do I need a powerful CPU to power this? I have a currently a E4700, 4 gigs of generic DDR2800. PSU I have a PC Power and Cooling 750 watt. So I'm belief that this should be able to handle the HDD load.

Thanks in advanced for any help.
