A portable 500GB HDD will comprise of a HDD, its casing and its USB (or firewire) etc, and will be able to plug into almost any display device, as wee see nowadays. Even if you were to consider a 25GB BluRay discs, that would still mean you'd have to manage 20 such discs. Hence the eventual cost factor will go up. In case the discs are not re-writable, then this cost will always keep escalating.

Yes, if you need to carry 500GB of data around the place, a portable HDD is definitely the way to go.
However I disagree with the cost.  Optical media is definitely less convenient, but you can't beat the cost of storage.

SSDs are still fairly premium >_>  I can get a 640GB HDD for less than half the price of a 30GB SSD.
As for shock protection, can't say it's too practical, unless newer drives are different.  Lost my WD 80GB 2.5in HDD when it fell off the table (about 0.5m high), and it was off and in a casing >_>
