Buying an External Hard Drive

Generally speaking it doesn't matter which drive you choose. I would suggest to read a couple of reviews on Amazon for the exact drive you want to purchase though.
A couple of random thoughts:
- 2.5" drives have an internal power supply but are more expensive
- 3.5" … (small) external …. inexpensive
- interfaces: USB 2.0, e-SATA or firewire
+ every cheap drive has USB. Reliable, reasonably fast, nothing to complain. USB is a bottleneck, but the handling is foolproof.
+ e-SATA is the internal hard disk interface pushed through an external connector. Drives are more expensive but also faster.
+ firewire an older and fast standard. I know nothing about it.
- The differences are only interface and connector. The actual drives are the same.
A cheap USB drive should be enough. Maybe a 1 TB drive for ca. 80$. Smaller drives are probably relatively more expensive.
