Long-term storage

Iain always tells me I should just get a hard drive and copy things to it for long-term storage.

Even though it’s more expensive per gigabyte (see
Media Costs“)
it’s a lot faster and easier to deal with.
It saves you tons of time, too.
Backing up hundres of gigs of data to 4.4 GB DVD’s gets really old after a while.

However, it occurred to me that there is a very good reason not to use hard drives for long-term storage:
connectors change over time.

SCSI and IDE are getting more and more rare these days.
Some day the same thing will happen to SATA.
Yet, even the most modern optical device — the Blu-ray drive — can still read the very first optical format: the CD.
