Is a “portable” external hard drive for storage-and-carry only, or can it be used alongside your computer?

I want an external HD to store my music library and wondered if a portable version (such Seagate's FreeAgent Go) was any worse or better than a regular external HD like a WD myBook or LaCie. Thanks!

Answer
Just consider the usage of the external hard disk. If you plan to use it as intensively as an internal disk, you should check out the transfer rates.
This varies with disks and especially with the interface used: USB 2.0, eSata or FireWire.

What is the best portable 500gb external hard drive for HD video editing?

I have a Macbook Pro i7 and I need a portable harddrive that will keep up with my video editing so I don't drop any frames. I don't know if there is a big difference between a Seagate FreeAgent GoFlex Pro 500GB USB 2.0 7200 rpm vs LACIE Rugged 500GB 7200 RPM USB Firewire 800. Any ideas or suggestions?

Answer
Go Firewire. It will have at least twice the data throughput rate as the USB 2.0 drive. RPM has little effect on external drives, as the data interface (USB or Firewire) is almost always the limiting factor.
