External HDD's for movies.

[fitto13]

I'm looking for a large external drive to store and play my movies through my MBP.
Which drives do you guys recommend for this?

Will the spindle speed of the drive or the fact that it's firewire or usb change the drives playback of a movie?

Am I better off to get the most storage for a reasonable price?
or
Am I better off sacrificing some storage (1TB instead of 2TB) for a firewire connection or faster spinning drive and pay more?

I have a budget for the drive, so it would be a smaller 'faster' drive or a larger 'standard' drive.

Obviously, I'll go the bigger and cheaper one if the spindle speed and it's connection type doesn't affect movie playback.

Cheers for any help!

Mac OS X offers 35MB/s via USB 2.0 and up to 65-70 MB/s via Firewire 800.

Every current HDD (2.5" or 3.5", 5400RPM or 7200RPM) can sustain those speeds.

Compressed movies don't need that speed though, as even HD movies using an MPEG-4 codec (Xvid, Divx, H264) usually don't have data rates of more than 2MB/s.
