A NAS can be pretty much the same thing as your hard drive in a box, except that it's connected over your network, rather than your USB port. That's your most basic comparison. There are advantages either way. With a USB drive, you can usually plug it in this computer, or that computer, and use it fairly simply. But computers aren't always that good at piping a lot of data at speed, for a prolonged time, through USB. I've certainly encountered that. And you get the fun and games of some PCs that won't boot with a USB drive plugged in, as they try to boot from it, and refuse to proceed. I've encountered that, I'm stuck with it on one seriously annoying PC. With a NAS drive, you need to have a spare network port. If you have a a router or a switch, no problem. But if you have just one PC plugged into your single-port modem, and no spare network port, you're stuffed until you buy a switch or another router. Having said that, once you do have the available port, it's a standalone device, not just a dumb hard drive in a box. If my computer crashes while I was reading and writing to a NAS, it doesn't upset the NAS, just the last file sent to it. But with a USB drive, a computer crash can do worse. I know journalling file systems are supposed to help, but they don't always, and you may not be using one on the external drive. The NAS doesn't have to be plugged directly into the PC, it can be anywhere on your network, or even externally, accessed by any computers on your network without any picking it up and plugging into that other computer. And that access could simply be reading the data from anywhere that you're working, to using that one NAS for backups for any computers that you have. For either drive, they often come with an awful power supply, but at least NAS drives are intended to be powered on 24 hours a day, and should be designed to cope with that. USB drives aren't usually designed with that in mind, and you may suffer from the typical modern "design it to minimum specifications" syndrome. -- [tim@localhost ~]$ uname -rsvp Linux 3.9.10-100.fc17.x86_64 #1 SMP Sun Jul 14 01:31:27 UTC 2013 x86_64 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists.
