Think hard drive space is expensive?
Another history-type post here, but I have to begin by stating that I have been thinking about adding a very high-capacity NAS, or Network Added Storage, drive to my system at home. They’re expensive, but they can serve as your own personal cloud and recover all your data without interruption in case of a crash. They also connect to a router as opposed to a PC so they can share data to all devices on a network, or in fact devices all over the world if they have the proper permissions. You can read more about them at this link.
Storage is important today, but in the glory days of the ’80s it was at an absolute premium. Just to give you an idea of the level to which that was true, have a look at these couple of ads for 10 MB hard disks from way back when, meaning the 80s (the first and third are from vintagecomputing.com, a great site!).
