    Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

    My computer doubles as a space heater.

    I don't really have a preference.....I've never paid much attention when looking at NAS or NVR/DVR HDD's.

      If given a choice, why would anyone prefer SMR?

      Unless you mean, taking also capacity into consideration.

        I have an SMR drive in my main system. It's only a data drive (no software), so speed doesn't matter that much. It's one of those drives that wasn't advertised as an SMR drive, but it's good enough for what I'm doing.

          Whatever I got the better deal on. Not sure what my server backup drive is... 4TB iron wolf NAS drive I got at a pawn shop for virtually free and then RMA'd since it was still under warranty. The main drives are CMR's for sure... desktop 1 platter 7200RPM 250GB seagates (15 of them). OS drive is a CMR Seagate 7200 80GB (smallest SATA drive I've ever seen, only good use for it).

            CMR. Unless managed properly, you can expect problems with SMR drives.
            Useful conversions. I don't "speak" imperial. Please use metric, if you want to address me.
            1km=1000m=100000cm, 1inch=2.54cm, 1mile=1609.344meters, 1ft=30.48cm 1gal(US)=3.785liters, 1lb=453grams, 1oz=28.34grams

              I did a lot of research before I bought two new 6GB NAS drives. Nobody has anything positive to say about SMR's performance or longevity. Price and capacity seem to be its main advantages but, if you're looking at a once-every-five-years purchase like a NAS upgrade, you might as well shell out a few extra bucks for the more reliable solution. Rebuilding those drives is a pain and takes forever.

                Yep. 24 hours minimum to write 4TB to my 4TB external drive (which is SMR), and at least 18 hours to immediately read it all back and write to to a CMR drive.

                Meanwhile, I can move 4TB from one CMR drive to another in 10 hours.

                  Meh, where's the option for longitudinal recording?!
                  (OK, I suppose that still falls under CMR. )

                  My 80 GB Samsung-made Samsung PATA/IDE HDD is still happily clunking away as we speak here.

                    That's no surprise, it was made before Samsung exited the HDD market and basically sold the whole division to Seagate. I suffered a major data loss event thanks to a 2014-era Samsung external drive, which was nothing more than a rebadged Seagate drive.
