External 4 Bay HDD RAID Enclosure connected to PI

[DLD]

Hi All,

I hope this is the right place, please let me know if not. I've had a look in both FAQs but couldn't see anything that stood out about this issue.

Software
No overclock, unsure of exact Xbain/XBMC version, but if they are not the latest I will update soon. I usually install Transmission and Flexget onto my Pi.

Hardware
I have a 512MB PI, use a D-Link Wireless N Wifi Adapter, an Apple USB charger with cheap cable, and a cheap HDMI cable to my TV and currently a 4TB External HDD with two partitions one 2TB NTFS and one 2B FAT.

Question:
I've been looking at getting an external enclosure for some HDDs. I don't think I want a NAS right now, and it does not need to be a RAID either but preferably if it looked like one HDD to the PI that would be great (on a separate note the two partitions on my 4TB USB HDD often randomly swap mounting positions from usb0 and usb1 after powering off, which isn't ideal).

My question is, will a 4 Bay External HDD Enclosure just work? Often the ones I find say they need Windows/MAC but I'm not sure how important that is? The last one I looked at was this: http://www.pccasegear.com/index.php?main_page=product_info&products_id=21639 with the hope of putting in 4 of these http://www.pccasegear.com/index.php?main_page=product_info&products_id=22816.

Does this look possible? What should I be looking out for?

I'm worried the enclosure might need special software that can't run on the Linux/PI/Xbian. Also that the HDD size might be too big for the Pi.

Cheers for any and all help/resources.

Dave
