The latter shows up, even though that's not what you're looking for. Though you may need that too, because the host eSATA port DOES need to be port multiplier capable. Not all are, and most MB ports are not PM capable either. So you may need both the adapter card in the "main" PC, and the PM in the remote case. That would be the case even if you just got a drive enclosure IF it didn't come with a card. The enclosure has the PM part built in, and they often come with a card for the host PC, since many/most PCs don't already have ports that are Port Multiplier capable.
Sorry if I'm making this confusing.
Edit: you said you can't get the Addonics there, but they are available from a lot of vendors (see
here). Also, I mentioned that I bought one of the Meritline PMs, but the other one I have is a Datoptic SPM3726, if that helps. There are a lot of them under different names, but they are all pretty much the same.
It's possibly because of the larger market you have in the States, it invariably means you have more to choose from and there's sufficient demand for even relatively obscure products due to the much larger consumer base. Sure, the EU is even larger but it's way more fragmented for stuff like this - someone in Idaho can happily shop online and buy stuff from a specialist store in Florida...in theory I can do that here, but a specialist store located somewhere in Denmark is hardly accessible to me here in England even though there are similarly no customs or import restrictions.
Virtually ALL of the port multipliers here are of the host type rather than the sort you can put in an enclosure. The Addonics one you've provided a Google Shop link to is of the Enclosure type and isn't designed for a PC case with PCI expansion slots and, whilst the Addonics reseller here does the card it doesn't sell the necessary adapter you can screw onto the rear plate which probably costs less than a buck

I;ve found a few port multiplier cards that look right mostly from Lycom, but so far, they've all lacked the necessary eSATA port - whilst they're fine for fitting inside a PC tower and don;t require a mobo, they are strictly "internal" only and just take one SATA port and turn it into five. I guess they'll be for people who have space but are short of slots on their mobo.
It's all so frustrating, I'm nearly there but not quite.
This all said, Addonics do some quite nice little hard-drive enclosure standalone units (which that UK store does have) at fairly reasonable prices. They only hold four drives, but probably by the time I need extra storage, 4Tb drives will have appeared and four of those would keep me going.
You weren;t being confusing at all, I was just being a bit dense, plus, there's the issue that things that are relatively common and easy to locate where you are just aren't around over here.
Thanks for taking the time to put up with me and my endless questions. It's all fascinating stuff. AT least I got the basic principles right!
