Page files/swap files rewrite often and wear out ssds
Actually, the small reads/writes of the Windows swap file are an ideal application for SSDs.
Microsoft said so in the Windows 7 days.
But the wear out problem is real and not the fault of swapping.
It's because in the last few years, SSD technology hasn't been improved.
We're being lied to. The controllers improved, but not the storage technology.
What's happening is this: The count of cells does barely increase.
Rather, a single cell is forced to store more and more states.
However, this will decrease life time, because the cells aging process is much more of a problem as it originally was.
Originally, SSDs used SLC - two states 0 or 1 or 0-49% charge/ 50-100% charge.
Then MLC came along, creaing fozr different states - 00, 01, 10, 11 or 0-24%/25-49%/50-74%/75-100%.
Then came TLC and and so on.
As we see, the gaps get smaller and smaller and storage capacity increases.
The problem is when the cells degrade, the charge goes down.
In an SLC SSD, there's little problem if a few percent do drop over time. But on the latet, it's critical.
Long store short: Quality of SSDs goes down as capacity goes up.
Because the cell count doesn't increase.
Because we consumer are greedy, not willing to pay what good SSDs are really worth of.
The newer the SSD, the worse it is.
Except for the increasingly advanced controller, which is being tortured by being forced to decipher the mess of those cells.
Edit: Analog to this is the increasing use of consumer grade SD/SDHC/SDXC cards in favor of serious/professional typeCompact Flash technology (CF never was end user technology,
it was intended for higher end digital cameras and embedded use) .
We're willing to trade in quality for cheapness/capacity so to say.
Instead of using CF cards of known origin with a guaranteed to work IDE interface, we're switching to Chinese no-name IDE/SD adapters with a bad soldering job.
Along with that cheap 2TB MicroSD card (SDXC) from China, as well.
Personally, I think we don't deserve any better if things release their magic smoke.
It's shameful how little professionalism remained in the IT fields.
We reached a point where food and drinking is more pricey than technology. Or rather, the other way round.
Even back in the old days, photographers valued good film for their work.
They knew that a cheap film would give a photography of low detail or colour accuracy.
Or that a good camera, their primary tool, has to have a quality lense.
Nowadays, however, we always blindly believe that technology improves all alone and that things can only go better and better.
We feel so proud of ourselves, pat our selves on the imaginary shoulders
and do spend little thought on how this is actually possible.
Maybe a bit more modesty and self reflection would be good instead.
Let's remember - If you're keep saving money, you'll end up buying twice. 😉
The Titanic sank because iron bolts were cheaper than steel bolts, among other things.
Economical thinking risks the life of people.
