I am looking for some advice about an esata enclosure setup. I would like to move into a multiple drive array for FCP and would like to know how the port multiplier works.

I already have figured out that hardware RAID is superior to software RAID. My question is whether I can get an enclosure with the parts that handle the multiplying (I already have a newer technolgy extenders cable product), or whether I need both that and a card which handles the multiplying?

If someone could explain to me what I need, and hopefully how it works, it will be much appreciated.

Thanks.

    Dunno what an extenders cable is, but I'll describe my set up. A five slot burly box with 5 drives installed. Currently they're 500 gigs each, about to migrate them to 1TB drives. Sonnet Tempo sata card-- which gives me 4 e-sata connections. One connection goes to the box, which itself has a port multiplier to each of the drives. If needed, I could connect 3 more of the same sort of boxes and quite easily have 20TB external FAST storage. And the best part is that it is CHEAP.

    Our Brian Conner is a VAR and helped me put this package together. AND recommended which drives to get.

    I'm now guessing that you've attached an extension cable to the wire strap inside your computer and run it out the back of your machine. Yes you could do that. One thing I worry about is whether having an opening in the back of your machine would mess with the rather well designed ventilation system.

    If you use an enclosure that uses port multipliers, you must have a card that supports port multipliers.

    Therefore the Newertec wont work with a port multiplier enclosure

    My computer supplier would only sell me a card and enclosure combination that were comatible, so I suggest talking to your supplier and dont buy individual items that wont work together.

    I have a great Sonnet Fusion system that has a built in Raid, consisting of-
