Precisely why I had the SSD (used for in-car navigation). Though, I have read of SSDs suddenly failing, more due to bad components than writing too may times hence the caution.

Happens to both SSDs and HDDs; almost all computer parts follow a
bathtub curve to at least some degree.
For desktop drives where impact is rarely an issue, the controller board going can be just as sudden. For both SSDs and HDDs, poorly cooled systems are IME biggest culprit but some drives of either type will just die even with great cooling and no impact/shock. Mechanical failures not due to external forces aren't as frequently catastrophic on HDDs as they used to be -- some folks here will probably be old enough to remember when you had to park HDDs before shutdown :)
I'm very happy to be back in pure software development where hardware can be treated as a virtual resource in most cases, but I spent one of the most interesting parts of the HDD-SSD transition for data centers (2010-2015) in a couple of positions where I did a mix of development and IT management. I got far too familiar with the constant drip-drip-drip of HDD replacement rates.

Generally, yes, they are far more reliable. I have had a few SSDs fail within the first months of usage, but so far none due to old age/abuse yet. BUT, the big difference between SSDs and spinning rust HDDs, is that the SSD failures I've seen gave no warning. One day it was working fine. The next, it wasn't responding.

IME, that's a fairly common failure mode for HDDs as well, both the "motor no longer spins up" mechanical failure and the "controller board dead, computer doesn't see drive."

Always, no matter the technology -- Backup, backup, backup! How much is your data worth to you? How much $ would it cost you to get back to normal again? How much would you be willing to pay to get that data back? Usually the answer to that is far more than the cost of a small portable hard drive. I don't have an issue with using HDDs as backup drives, in fact that's what I use for offline backups. For most people, the "3-2-1" style of backup works well. ie: 3 total copies of your data... 2 on-site (one on the machine, one external drive), 1 off-site in case something happens.

Excellent advice. I've moved to SSD for most of my non-bulk backup (the bulk being ;the tens of terabytes of media on my server at home), but it's still a bunch more expensive to do so. One thing that isn't clear for either SSD or (modern) HDDs is the long-term viability of cold-storage data. The oldest still-running HDD I have was 28 years old last summer when I dug it up at my mom's house -- and still has intact from when I was in high school (although it took some work to did out of a dead laptop.) The oldest SSD I've got is 11 years old, and still has readable data on it. OTOH, bit rot is real, and modern SSDs use a much smaller feature size (and this a much smaller amount of captured electric charge to read) than the IIRC 50nm of that first-generation Intel drive, and the density of magnetic media has gone up very rapidly as well.
Optical media specifically designed for long-term data retention, or tape, are probably the most secure ways of very-long-term cold storage. These days of course, it's also just practical to copy everything onto a bigger drive every few years, and then if one old copy dies you have a newer one (although at a certain point, you need to worry about bit errors on copy.)

What you're proposing has no possibility of working--it's impossible to run Windows from an external drive. You clone to an internal drive. (It's not hard but I would strongly suggest getting help from someone who is comfortable working on the innards.)

Not sure about MS's program, but for Macrium/Acronis/Clonezilla/Gparted, there's nothing wrong with cloning to an external drive and then swapping that drive (minus the external case) into the machine, or cloning off of that onto a different internal drive.
Also, with some poking, you can run Windows from USB. It's miserably slow (even on USB 3+) so it's basically only used for creating Windows-specific rescue environments, but it is possible.
