Well you don't know me in real life. I actually don't hang around people much, but when I do I'm pretty outgoing. (I'm not socially awkward or anything, I just don't have a lot of time to spend hanging out with friends. Lot of sports + lot of homework = less time for friends.)
I'm only immature with my friends in the real world.
My solution to this problem was getting an HDD dock. In the long run it's cheaper, more convenient, and/or safer (in terms of data integrity) than screwing around with portable HDDs or DVDs. When I need more space I can just unload stuff onto an offline disk, or buy another one or two TBs without having to sell internal organs.
I recommend using an eSATA port with the above solution.
Huh, I've never heard of this. What's the process of adding/removing a hard drive? Can you hot swap them? Do you use a dock that supports multiple hard drives? eSATA performance is approximately the same as "standard" SATA, right?
A dock is just a hot-swap bay/enclosure. Apart from hot-swap it does not differ from other external enclosures. Some have place for more than one disk. It is not much cheaper.
One could buy an internal SATA HDD and plug it into eSATA port, if one has power for the drive. Some motherboards did include a bracket with eSATA port and Molex and external cables. You essentially did connect your disk into internal SATA port (with the eSATA hot-swap support).
One could buy external enclosure, where one plugs in the drive and which have their own power supply. I have one that I can connect either PATA or SATA drive to, and then use either eSATA or USB 2.0 link to computer.
One could buy "dock" that is just external enclosure with open hole to plug the drive in.
One could buy "external drive" that is just an external enclosure with a drive already in it and usually only one connector protocol. If it is USB, then the power might come via USB.
Hot-swap is hot-swap. USB is an example, but there it is the USB-device that connects and reconnects. Servers usually have disk hot-swap; you don't power off a server just for one disk needing replacement.
