    I just got a Mac Mini I am using as a media center. I need more space for all our movies and music. I want a USB 2 RAID 5 thing, that I can add drives to as I need more space and it will rebuild the array. Wanna start out with 1TB (3 x 500GB) and have space to add a couple more.

    What is the best and cheapest one of these?

    There aren't really any inexpensive external RAID enclosures. The ones that appear to be relatively cheap actually expect you to have a RAID controller in your machine, and the enclosure is just a box for the drives to sit in.

    There's the Drobo, I suppose, but it's $500 without disks. To get 3x500GB in it, you'll be looking at another $345 to set it up with these. That, and the Drobo is kinda sketchy about disclosing how its array works.

    Bottom line: if you wanted expandability, you shouldn't have gotten a Mac Mini.

    Actually, you don't know what you're talking about. The Mini has 4 x USB slots, and I can run as large a RAID array as I want on it. It is endlessly expandable. It is the ideal media station.

    But it does look like I'll be adding 500GBs one at a time for a while, cause I don't wanna pay $500.

    300-700 for an enclosure with trays. Also, why USB? Firewire is faster and around the same price.

    Firewire 800 is only marginally faster than USB 2.0, is it not? And more expensive?

    Actually Firewire 400 is faster than USB 2.0. On paper, USB is faster but in reality, firewire kicks the crap out of it. USB has way more overhead so it can't achieve its max throughput. We got bored in the office one day and ran disk benchmarks on a handfull of USB2.0/Firewire enclosures we had. The firewire won every time.

    It was the only thing I could find. Suggest something better.

    Oh yeah, we have drives at work with both USB2 and FW400, and any time I have to use the USB2 the operation takes twice as long as it does with FW400.

    USB2 just has higher peak bandwidth, that's all.

    I have a firewire 800 here, but I don't think the Mini has that.

    I know you said usb/firewire as your connection method... but why not a nas-type solution? Would the network speeds be less than what you're looking for in usb/firewire? Honestly, i don't remember what speeds usb and firewire run at... sorry if i'm talking random shit.

    It's not what usb/firewire is really designed to do. It's like saying "show me a sports-car 4-door-sedan under $10k brand new that is street legal in california" Not gonna happen. Do some people make a storage unit for it? Yes. Does it make it ideal? no.

    Does it do the job its asked? If so, is it ideal? ;)

    How much more are the NAS appliances, and can I play 1080p video over 802.11g okay?

    technically, 802.11g works okay. Real-world results vary. Latency consistency and packetloss are going to be signifigant factors.

    But on 100/1000 ethernet, I would be fine playing HD video from a NAS appliance?

    yes. 100Mbps could easily support compressed HDTV (generally MPEG4, now-a-days). 1000Mbps I believe could run un-compressed.

    Transport Stream MPEG 2 (MPEG-TS, what is used for OTA HD) 1080i plays fine over 100mb. Unless you are getting source files from the studios or ripping HD/Blu-ray, that is as big as HDTV gets. Cable/Sat compress it more to get it down their pipes.

    In that case I think I'll get one or more NAS appliances and share them to the apple via NFS. Anyone got recommendations on one of these?
