    Twelve (12) SATA RAID system scalable to 20 drives would do plenty good for you...

    Add 11x 2.0TB WD green @ $80.00/ea for raid5
    or
    11x 2.0TB WD green @ $80.00/ea for raid0 ( no redundant)

    You still have ability to expand up to 20x HDD
    If you go with this solution, use the email notification, it saves you lot of unpleasant supprises
  3. greens will be REALLY slow though, even a blue isn't that much more and gives you 7200 RPM performance.
  4. There have been concerns with using the more modern WD green/blue/black drives in RAID. RE4 WD drives are designed for raid arrays and don't have the 'problem' built into them.

    There is a different from GREEN vs 7200rpm drive, but the objection here is LOW COST and someone19 does not mind 10~20% slower :-)

    There are certain raid card does not like green or desktop drive, but not every raid controller does that, particularly the hardware assist raid card does not care whether the HDD green or desktop

    Also RE4 is not a low cost HDD
  7. Yes, I know RE4 isn't a low cost drive, and wouldn't be acceptable for the OP's purpose, I guess I should have mentioned that looking at a manufacturer other than WD would be in order if those potential array problems worry the OP.

    Me, I'd want to know and wouldn't build an array of that size with WD Greens.

    I am not in a position to recommend an alternative drive however, as I haven't been versed in the drives available these days. I'm looking at the spinpoint F3 drives for my build, but that's not going to fit with the purpose of the OP's request.
  8. Any desktop drive would work. You don't have to use WD.
    Seagate, Samsung or Hitachi for that matter
  9. Since RAID arrays at larger capacity comes at higher cost.

    Is there any raid controller that maintain hard-disks to be fit on motherboard and supports expandable hard disk ports.

    Someone posted a real beauty here recently. It was Firewire2 in this thread: http://www.tomshardware.com/forum/forum2.php?config=tomshardwareus.inc&cat=32&post=266995&page=1&p=1&sondage=0&owntopic=1&trash=0&trash_post=0&print=0&numreponse=0&quote_only=0&new=0&nojs=0

    The device is: http://www.datoptic.com/esata-hardware-raid-controller.html . With 2TB drives, though, you would need two to get 20GB raw capacity, three for RAID (and you'd have three smaller volumes).

    And here, before me, is Firewire2 with a one-device solution. Firewire2, do you work with this stuff for a living, or do you just have an expensive hobby?
  11. Yes, i'm an IT consultant, of course I make a living in data storage field :-)

    I use some of DATOptic stuff to built custom storage....

    Here is what I did with those raid controllers

    40TB NAS consumes 180W power

    This is for my client :-). If you need help PM me, I will do my best
