Hard Disk Drives
SSDs may have made them unfashionable, but I don't mind; as mechanical devices go they're still more than respectable.
From my point of view, the only thing “better” about cars is that you can tinker (which I have no desire to do, beyond basic maintenance if I owned one).
I'm not entirely convinced SSDs will maintain that much of a reliability advantage (apart from shock resistance) either, given the move to more bits per cell (requiring ever‑finer voltage level distinction) in pursuit of closing the price gap. My expectation is that they'll settle on a similar lifespan to HDDs (possibly going a step too far before correcting), and even previously-formidable Samsung have put out some serious duds lately.
Overall the only unequivocal SSD advantages are speed, shock resistance and silence (with much-cheaper 5000–6000rpm* HDDs being near enough to silent for most people anyway); they may have better average reliability, but it certainly depends on which SSD and HDD models you're comparing.
(Even today I'd trust an old Seagate Barracuda 7200.7 or a middle-aged HGST or WD Caviar Black/Se over SandFarce-controlled SSDs or Samsung 870 EVO, and probably those with YMTC flash for that matter; provided the individual HDD is still healthy of course…)
That being said, I'd probably bail out of current single-platter drives, as (especially being the most immediately-threatened by SSDs) they tend to be the most cheaped‑out in their construction (particularly with Seagate being hell-bent on dragging out contact start/stop as long as possible, using it on a 1TB platter in Pharaoh Oasis and Hepburn Oasis ); if you're using 1TB (or even 2TB) for any serious purpose you can probably afford an SSD of that capacity, and 4TB+ HDDs (where the SSD price gap still matters) remain multi‑platter (which having “enterprise” variants, are more likely to be properly‑built).
*Let's not forget Fujitsu's MEA3320BT of 2008, now something of a prized collectible as the only 3600rpm FDB drive in the normal 3.5″ form.
Maybe if Fujitsu held onto their HDD division rather than selling it to Toshiba the year after, we could have seen some further developments…
On a side note (having mentioned cars), while mechanics appeals to many people as being more “intuitive” (although harder in many ways than electrical engineering), the noise puts me off; electronics has the significant benefit of being quiet to work on (barring catastrophic failures).
“Are you OK?”
If you have to ask, then you're not. Just say if you have a specific concern…
