Any feedback on those super large back-up HDDs?

So for backups I have been using a Thermaltake HDD caddy.  I purchased a few 3TB HDDs on pop them in and out when needed.  But I see Seagate has the large 8TB backups like this:

For 8TB the price seems pretty good.  At Xmas they were at $149!  But had to snag a GeForce 1080 first, ha!  So I was just curious if any simmers have purchased/used these monsters?  If so, do you break them down into different partitions or leave them whole?  Pros? Cons?

I have the ST8000AS0002 as a backup drive for my NAS, which is supposedly the internal version of the drive inside this enclosure.
It has been working fine for about 2 years now. It's an SMR drive so there are some limitations (plenty of articles online explaining SMR), but for backup/archive use, this is an absolute non-issue. I've never noticed any slowdowns when copying data to it since the drive is smart enough to mask the drawbacks of SMR for the most part. The only thing to keep in mind is that you can't use it in RAID, and if you do a lot of random writes to the drive (ie. using it as an ordinary OS/application drive), there will be the occasional slowdown as the drive has to rewrite a lot of the shingled tracks.
