I'm wanting to replace my external hard drive (already) as the enclosure is simply too unreliable to be trusted, plus the spare 160GB drive I had isn't really big enough :p.

At PBTech, there's a $10 price difference between a 320GB 5,400rpm 2.5" drive and 7,200rpm drive of the same size and capacity. As I don't have a lot of money, is it worth spending the extra $10 on a faster spinning drive (remembering that I need to buy a new enclosure as well)? THe drive is used to store large files, including SD and HD video.

TL;DR :stare: - 7,200rpm or 5,400rpm, (which is cheaper)?

Fort an external drive it would be fine, less heat + less power consumption, although the difference these days is very marginal. I would go with a WD green drive.

And if there's no good reson to use 2.5 inch instead of 3.25 inch, then go with the bigger drive. Might as well then also go for larger capacity. Note however that recent reports here have cast a lot of doubt on the reliability of 2TB drives.

The reason to go with 2.5" is for portability: no point carrying around a 7" netbook and a hard drive bigger than the computer :p

I originally went for 3.5" as that was the only spare drive I had.

If it was me I'd buy the 7200RPM for speed.

USB 2 is going to be the bottleneck I would safely hazard.

I would go for a 5400rpm 2.5" drive for portability and low power usage. If you're using a netbook it will be more than enough, and the low power use will mean you can plug it in without an external power source providing you have 2 USB ports.

The only reason to go for a 7200rpm drive is if you are going to install applications on it, as the shorter seek times will make a big difference.

as pointed out either drive will be faster than the USB interface, I'd stick with the 5400 as you'd be unlikely to notice the difference in an external device.

For an internal boot drive the faster the better, for simple storage speed has little effect.

PB Tech didn't have any 5,400RPM drives left so I had to get a 7,200RPM one. :p

Thanks anyway.

Thank gosh. Gotta say unless it were other components failing, my seagate 7200rpm.12 smoked the crap out of my 5400rpm in terms of game loading times and ease of streaming content.
