Why people believe this myth about digital SSDs being better than physical real HDD disc drives ?
- The fact is if SSDs are not powered for decades (10 years+) it erases itself when unpowered.
When no power is left in SSD to retain it's bits and bytes then it empties itself.
Then all your hard earned data is gone.Only trustworthy are HDD disc drives.
- I myself even make sure that my modern PCs have large HDD disc drives.
- I have 30-40 years old disc HDDs still working in storage.
- I love my data and want to preserve it. Only HDDs offer this longtime reliability.I agree 100% with all of the above. Add to that - vintage computers and more importantly the software they run are not designed to work with solid state media, and might actually provide a poor experience compared to using a spinning disk. I've personally had issues with anything older then 775/939 PCs and SSDs. That includes socket A and 478 stuff (but only when win9x and DOS is involved).
My guess is people run away from HDDs in vintage computers because of how physically fragile they can be. Getting one shipped from across the world might turn an otherwise working vintage HDD into a paperweight.
Statments on these posts are outrageously wrong or at the least misleading and no one who cares about their data should follow what is written there.
First, thinking that data is somehow more secure in HDD is blatantly wrong. MTBF of SSD is far superior compared to HDDs. As they represent very different kinds of technology, the factors affecting SSD reliability are very different from HDDs. For example, the technology used in SSD is a factor in itself and if you have a system with lots of writes, MLC or TLC are generally considered better solutions, although denser (and faster) technologies can be used at the same level as long as you don’t fill the SSDs and leave some capacity on the drives.
The plethora of working HDDs in my collection - some dating all the way back to 1990 - proves that magnetic hard disk drives are a proven and reliable technology. I will admit to being a little biased by my personal experience, as throughout the years I've seen far more solid state media (SSDs, flash drives, DOMs) fail then hard disk drives - by a factor of 3 to 1 - and considering I've been working with large volumes of computers for over 25 years, that's saying something.
If you need speed, solid state media is undoubtably the king. If you need reliability, well that's debatable. Right now my vote is for proven technology, but solid state media has potential - especially professional grade hardware.

If you want hassle free reliable compatibility with retro PCs, particularly pentium and 486 486 era hardware - then a period correct hard disk drive is the way to go. Solid state drives rarely come in PATA, and when they do, the command a premium over their SATA counterparts. SATA SSDs are also very easy to come by, while PATA drives are niche, and can only be found on sketchy sites like aliexpress and sometimes on independent web stores that sell retro computer gear - in limited number, where they again, command a (sometimes hefty) premium. I'm talking about native PATA devices, because at least half of the headaches I've had with running solid state media on vintage PCs relate to the controller interface. I've had issues with most SATA to PATA adapters, some work better then others, some don't work at all, while some seem to only work on certain types of motherboards or with certain solid state media. CF to IDE adapters are in the same boat. I've spent hours trying to reliably get various size and manufacturer CF cards running reliably on a Fujitsu S400 and several other devices with native bootable CF card slots, and it's always a crapshoot. Some cards work ok on some devices, but not others, and there's little to no way of figuring out what works on what without wasting hours. Then there are DOMs - Disk On Modules - basically industrial quality flash drives with an IDE interface - these are the most compatible of the solid state media I've tried so far, but they're also some of the most expensive, and in some cases pretty slow (since they're designed to boot off of once every few months when industrial machines are rebooted for maintenance, and that's it - read / write operations are not a concern).
My experience with using SSDs and CF cards on old computers has been very very poor, and I'm only trying to spare other users the trouble I went trough.
