external hard drives USB powered and Mains powered
Hi guys and girls of the virtual world!
I realy need some advice
I edit usig premier pro on my laptop PC and currently have a manis powerd external hard drive thats getting full.
I sit on a train for 4 hours of the day and would like to put my bum numbing commute to good use and do some editing on the train, but cant due to lack of mains power on the train.
Do you know if there are any advantges of mains powerd hard drive over USB powerd ones?
would a USB powerd drive be ok to use to edit with? will it be able to handle large files etc and be quick enough to use?
Im thinking i will probally need 500 GB…..
any help on this is very appreciated!

A usb powered drive will lunch on your lattop’s batteries, a large 3.5″ drive would be a power vacuum, there are small usb enclosures for 2.5″ drives which would be less power hungery, problem is the larger 2.5″ drives can be a tad expensive, if there is a power drop on your mode of transportation the problem would be moot, I’ve got a couple of 2.5″ 160gig drives in usb cases, and I have extra batteries that fit into my Thinkpad’s DVD drive bay, a 160gig drive will hold 10+ hours of DV/HDV, a 250gig 16-17 gigs, having edited on 4200rpm drives sucessfully I find 5400rpm drives a bit more economical than 7200rpm drives, and 160gig drives more economical per byte with enclosure than 250s

2.5″ drives would fine for the most part, but you should keep 2 things in mind:
a) Expensive: These drives are relatively expensive than desktop drives
b) Speed: Many of these drives aren’t very fast, which may result in degraded performance.– Aanarav
