I’ve had this box for almost ten years now, so I’ve been thinking about getting something new. Looking at the market, the new systems don’t seem to be all that much more advanced, though. So my question is, should I get a new one or just keep the old box and swap out the drives? What can a new NAS do that my old one can’t? And what kind of drives should I get? I have 2 TB WD Red something, is that still a good choice? I’d move up to 4 TB, of course. This box is only used as backup for my home stuff and a small business, I’m primarily concerned with reliability.
Have you checked the SMART values of your drives? Do they give you a reason for your concerns?
Anyhow, you should never be in a position where you need to worry about drive failure. If the data is important, back it up separatly. If it isn’t, well, don’t sweat it then.
How do I do that?
You can get a quick overview via DSM, I think in the Disk Manager. For more details you could jump into a terminal and use smartctl.
