Portable Media Storage

tell me any kind of disk drive (internal or external)
or other anythimg

It depends on the amount of data you want to store in the media and how often you want to do the media? For frequent travelers pendrives USB are the best. The storage capacity can hold up to 32 GB. Because of their small size, they can easily be transported in pocket.However If you want the disc large amount of data, then Hardisk USB phone which has capacity of 80, 120, 160 and 250 GB or more are best. Some external USB hard drives two connectors one for power and one for power + data. Make sure you get the drive with a USB connector.
I hope this will help.

is better to buy an external (USB hard drive)

Depends on what you need to.
If you want to store music files, say 200 1 GB and then just buy a USB flash drive of this capacity because it is quick and convenient (Transcend is the best).
If you want a bigger storage device, then you can try Seagate.

buy an external hard drive. The latter come in different sizes data.
The concert is 320 is perfect for movies and other things I think.
It fits simply in your bag too. I bet if USB 2.0 has more speed, it can also load an OS. But try Seagate.
