Best External Hard Drive

With FireWire, it is literally a "chain". Every device can communicate with every other device, and each has equal priority. You can mix FireWire 400 and 800, but not cross protocols (FireWire+ USB). Of course, if the data has to pass through a FireWire 400 interface in its travel to the computer or other device, it will be limited to that slower 400Mbps speed (which, incidentally, ends up being much faster in the real world than USB's 480Mbps). Basically, with FireWire, as long as there's a signal path between two devices, they can communicate. There's no direction either: every device has the same ports and there's no rule as to which way round devices have to be connected (ie I can plug a FireWire cable from my computer into one of the ports on the back of my Cinema Display, then plug a hard drive into the cable hardwired onto the display (the one in the bundle containing power, display, usb, firewire) and it will work.
FireWire transfers are handled by the FireWire interface card in the computer, not the CPU, allowing much lower CPU load, faster transfers and much less latency (which is why many professional audio and video systems use FireWire).

I have used my USB drive through my Logitech hub without any problems before. But I have since changed it because I just felt it would be better if the drive plugged in directly. I'm not sure what I will do if I get another drive in the future. Maybe I'll get a firewire drive also, my firewire ports are sitting there empty.

It comes with software to encrypt the drive as well as software tomanage backup etc. It even has its own drive diagnostics utility that will report the SMART status, do a quick scan or do a full scan for bad sectors. So scrub what I said about USB drives not reporting SMART status.
It is tiny and extremely quiet and puts itself into standby after a set time (which you can set). It even turns on and off with your computer.
My only concern is the new micro USB plug - I've heard the metal prongs on it aren't that robust and the plug can start to get a bit loose. So I think I'll be careful unplugging it.

I like the idea of Time Capsule and am I reading correctly that it works just like an Airport Extreme base station. Which means I can continue to add more external hard drives to it?
My other thought was to buy an Airport Extreme and plug a hard drive into that.
Does anyone recommend either of these options?
And can the hard drives be daisy chained in either of these options?

Unless you're connecting through Ethernet, access to the drive will be much slower than if it was connected directly. If you're after performance, you'll want to still connect it straight to the computer with FireWire.

Edit: I might be wrong. I think the 802.11n spec airports can probably stream high definition video. I found a post at the bottom of this page, the poster says he has no problems with his airport extreme and HD content.

LaCie drive---[FW800]---Mac---[2.4GHz n]---AirPort Extreme---[2.4GHz n]---Time Capsule---[5GHz n]---tv
so it may well be fine unless the network gets too clagged up sending the video from the AirPort/TC to the Mac and back again.
