Hi,
Thanks for these valuable tips, especially the one about SMR. I have
looked at the topic in more detail and I am really glad I did. Could you
suggest a way of finding non-SMR hard disk drives, especially at decent
prices?
Cheap is starting to mean SMR in more and more places. All the high
capacity lines that are decent are non-SMR - WD Red Pro, WD Gold, the
Toshiba NAS drives, WD/HGST Ultrastar drives, etc. They're also the
expensive ones.
I think what we're really seeing here is that in the 1-6 TB desktop
range, customers are price sensitive, and moving to SMR means the
manufacturer can drop the platter count, which is going to reduce their
costs. That, in and of itself is OK, but the way they've tried to hide
this from customers is pretty underhanded, and happily seems to have
backfired quite badly. WD in particular should never have put SMR into
NAS drives, where it was clearly unsuitable. I'm not quite sure what
they were thinking there - it feels like marketing were driving the
ship, and were drunk at the wheel.
This is a list of SMR drives - known to cause problems with Synology NAS
devices:-

Toshiba seem to have been somewhat more honest, but have some SMR drives
in the lineup as well. Details here:-

The real root cause here I think is this though:-

There's not much real competition any more, and we're now starting to
see the results of that in the way customers are being treated... At the
2TB drive level, they have to get the price down quite far now, as I can
pick up a 2TB SSD for £300 or so, which is faster, smaller, lower power,
and potentially more durable. So it's cut every corner you can....
