I am looking at Seagate SSD and HDD for backups in the 2TB range. SSD costs double but is it more reliable?

What brand of external HDD do you recommend as reliable?

I don't recommend "external" HDDs at all based on what I often see in PC Talk.

What I recommend is a USB dock that accepts standard desktop SATA HDDs. That way any failure of the USB hardware won't affect your existing backups; the dock is easily and cheaply replaced, and you can back up multiple HDDs in rotation and have most of your backup HDDs safely off-line.

I like this docking station because it has a cover.

That might be nice protection, but I'd be concerned about drive temperatures for some HDDs. I only use mine for laptop backups, so a cover isn't useful.

I have one of these:

Internal 3.5" drives have more capacity than 2.5" laptop drives. Are they more reliable?

I don't know, but I'd expect the 3.5" drives to be considerably faster; no need to worry about power consumption/battery life like a laptop drive.

I have had one for about three years and it's been excellent.  UASP support.  Hot swapping works.  Never glitched.  With a 4TB Seagate Barracuda the sustained transfer rate is 180 MB/sec, and random small access is also quite fast.  Can boot from it too.
