Hello,
I have some problems with my 3TB HDD in my computer, from time to time it disconnects and sometimes it makes my system freeze.
This was on my 8.1 windows and now in windows 10 it is even more common :-(
I think it could be HDD problem and not just software. (I even dissabled the turning off disc feature in windows, but it did not help)

I was thinking about home NAS server (what is NAS?), but I do not know, if is better to have just 1 drive NAS or 2 drives NAS...
If NAS fails, it does not matter if there is 1 or 2 drives in it. But if disc fail, the second one will still work, but still I will have duplicitly stored data (on my PC and also on my future NAS)

Thank you

do you mean RAID?, that is usually handled by the motherboard not the OS, you might want to look at your motherboard settings.
then again I haven't heard of NAS so my info may be old

NAS is small box, that is connected in your local network, it stores data and it is easier to share it among your PCs and other devices.

This is NAS. Not completely unrelated to RAID, but not the same either.
NAS can be in a RAID setup, but it doesn't have to be.

I like NAS for external storage. How I did it was with a raspberri pi (running samba server) + an external hardrive. It's cheap and you can keep adding as many harddrives as you want. At the same time the raspberri pi functions as media center (running kodi) for my tv.

NAS useful if you have couple of computers or media devices. For single comp it is a wasted money. You can make RAID inside of comp.

Do a SMART test of your HDD first. Check cables. Check power unit is it enought.

How many computers do you use to access that data? Because NAS is only a good option if you need to access the data from several computers, possibly even remotely. Or if you need a metric asston of storage for, for example, raw unedited video footage. If neither of those have a "yes" answer, then buy a new HDD or more likely a new PSU that won't drop wattage on that SATA cable this often.
If you decide to have a NAS because of that, then the next question is how sensitive the data is. Would it really hurt to lose it? If yes, then two-disk and RAID. If not, one disk is enough for home server purposes.

Two computers and maybe even remote access would be sometimes good.
I do not think that PSU is bad, it is just 2 years old, and disconnection happen even without any load. (I even changed power cable to this HDD and also SATA port, but it happened again. Next time I will change SATA cable to different one)

You are right, maybe just the one-disk NAS would be enough, because I have backup of my critical data on my second computer (it is old and with small HDD)

Sudden frequent disconnect is usually power drop. If it is not the cable (most frequent culprit), then it can be the PSU or the HDD itself. Just for this problem alone, I'd rather take a new HDD, not a significantly more expensive NAS. Heck, if you need only a single-disk setup, I'd just get a router with a USB port and plug an external HDD into it. Slower, yes, but for a cheap NAS it is more than enough. And if you use a 3.5" one with external power supply, you can get up to 6 TB of storage for about half the money a similar NAS would cost.
