I certainly want to do more analysis but as I showed in my reply to you, smartctl will not read this drive. From further reading I see that there may be workarounds for this too, but one has a performance penalty and the other depends on something I don't know how to verify (that the drive supports SAT passthrough despite the kernel thinking otherwise) and may carry some risk if I get it wrong.You should first look (and post) numbers about the state of your SSD (as I did). And maybe convert my numbers into 'human-readable' (years and TB)I found my way to the redoubtable ArchWiki and followed the steps to allow me to perform a manual fstrim on /home. It trimmed 64GB![:shock:]( "Shocked")
How embarrassing. I will dutifully follow on and set up a udev rule to make this tweak permanent.
What's the best recipe now for dealing with the fallout of punishing 1/8 of the drive so badly?
Would it be helpful to enlarge the partition to the full 1TB? Or what if I cloned the existing partition into free space and abandoned the original? Any way I can isolate and avoid the over-used blocks?
NB. The partition is about half-full (58GB).
If the SSD internal algorithm is terribly simply, buggy or bad, your issues might be truly, but just assuming that trim can be the magic saver is just too simple. You/we simply don't know how good that wear leveling algorithm is. Many people assume really simple, but that is more than a decade (or 2) ago. Only if you use raw flash like Apple did persist quite long in their phones (others already used managed flash) you can do your own wear leveling. But using nowadays normal managed flash, you have to rely on how intelligent the mapping of logical storage (sectors your Ext4 sees) to internal cells/blocks is. It can be very complex, it is a computer in itself that is in the SSD, and as indicated, statistics and logging via smartctl. For NVMe, there is even more detailed better tool.
So in the end, the real things count: How much did you pay for it, how much is the power consumption, does it get hot, do you like the color, I don't know why you buy things. In theory, as is reality with SD-card, you bought fake brand / counterfeit. And we have RPL NVMe now, which can be Samsung or some other brand inside. AFAIR, a trick also Kingston does. But if you are in love with a Raspberry sticker/logo...
If the stats/logs numbers are completely off, so not what you shall expect from an SSD for a certain price: Where I am (in EU), there is a law that enables you to return the SSD and get a replacement, or money back, I don't remember all the ins and outs.. This is beyond 2 year warranty period. Don't let you fool by big tech like Apple who let you pay for an option to get extended warranty more than the 1 year they stated or maybe stall do that.
[Regarding my buying priorities, my main one is not needing to buy another one for as long as possible.]
