my seagate 700GB external hard drive crashed. i never had any problems when watching movies directly from seagate via my laptop. i wanted to buy a portable hard drive now but a friend told me that it will run slower specially when watching movies directly from portable hard drive. Since they get power from USB, there will be a lag time and will create a frustration. Is this true?
Also which brand should i try now?
Answer
My 2 cents...
Portable hard drives that get power from the USB port are convenient but they can have problems.
Typically to keep the amount of power drawn from the USB port at a minimum, the typical USB powered hard drive used a slower performance hard drive.
In addition, some laptops can experience USB port problems if you have multiple USB devices that draw power from the port at the same time, particularly if you use one of those self-powered USB hub expanders.
As an IT professional, I tell users to get an external hard drive that has an external power source. Generally these are physically bigger and cost LESS per a gigabyte than ultra portable drives. Plus because they are designed to be "static" (not moved), you're less likely to have an accident, as in dropping the ultra portable drive or have a power issue. Plus you can pay a little extra to get a faster drive (one with a faster data access speed and a bigger buffer).
Also the external hard drives use the larger form factor hard drives inside the unit versus the laptop sized drives in the ultra portables - again, less likely to have disk problems.
I recommend looking for drives with 3-5 year warranties if possible. I personally have purchased Western Digital external drives and have been happy with them.

Answer
I believe you may be comparing a 2.5" drive in comparison to a 3.5" drive when you say one is portable and one is external (as they both are external ;)..)
Portable would be in reference to that it does not require an external power adapter but externals are bigger and require an additional source of power.
Performance wise the external will probably give you better performance as they are cheaper to produce and have a solid stream of power - but in comparison to portability they are a pain to have to plug in everywhere just to access your files on the go.
So the decision is up to you :)
Hope i've helped cheers!
