Question HDD for Significant Torrenting

[needhelp111111]

Context
The main drive I use for downloading to is beginning to experience errors, which I'm assuming is a harbinger of failure, so I'm looking for a replacement. Considering high-capacity drives can be expensive, I'm looking for a replacement that is going to be able to handle an intense workload and won't die out any time soon. I'm looking for at least 8TB, and likely in the range of 8TB to 10TB. Notably, I do not use RAID, nor am I interested in using it for the time being.

Usage
On average I torrent anywhere from as little as 750GB to 1.5TB per month.
My torrent client is usually active anywhere from a 3 to 14 hours per 24 hours.

Questions

1. Which is preferable, NAS or surveillance?
2. Consumer or enterprise?
3. Which models (e.g. IronWolf, Red, Skyhawk, Purple, Exos) are recommended?

A 4 bay Qnap or Synology box would be ~$400-$500, + drives.
Depending on what you have already, maybe those ones.

My 4 bay Qnap has been ON 24/7 for coming up on 3 years.
4x 4TB Seagate Ironwolf.
I have no concern that it would not serve your purposes.
Either the drives I have in it, or the WD Purple or Seagate SkyHawk


I asked about business or personal, because the fault tolerance and downtime considerations might be different.
Downtime with a business might equal lost revenue.


For this single replacement drive, my personal recommendation still stands with the WD Purple.
