I don't think overprovisioning is that common to be used in most SSDs. And yes, wear levelling exists, but rearranging reduces cell health too.

Indeed it does, but far less than constantly rewriting the same 10GB.

Not sure what you're referring to with the overprovisioning. Spare blocks are different (although technically it is very small overprovisioning, but not in the normal sense). For example I have the same SanDisk SSD Plus as pictured in OP and SMART attribubute 05 is "Reassigned Block Count". On my Samsung 980 Pro it's 03 "Available Spare". Those SMART stats indicate how many cells/blocks have failed and have been reassigned with spares. HDDs have also long had spare sectors (SMART attribute 05 Reallocated Sectors Count).
