Thank you HWTech, I just ran DriveDX and my Mac has a failing disk.

FYI, the report you posted was only for the SSD. The SSD looks good.
Oddly, my spouse's newer iMac drive failed spectacularly a month ago. He only had a Carbonite Backup and it will take over a MONTH to restore his data.
Yeah, that is one of the downsides to online backups. They are good if you want an off site backup in addition to your own local backup. Some of those online backup services will also place the backup onto a drive & ship it to you, but to me that would be a bit of a security & privacy risk unless it is encrypted.
Looks like a trip to the Apple Store soon...
FYI, you will do better buying an external Thunderbolt3 SSD which can give you the same or better performance than the internal Fusion Drive even when it was new (depends on the external SSD though). A USB3 SSD with UASP support would give you about 400-500MB/s transfers which is Ok for average use, but may be insufficient if you are doing HD video work. Plus when you retire this iMac, you can re-purpose the external SSD for another computer for storage.
An official Apple repair will only replace the internal Hard Drive with another Hard Drive and it will be expensive.
If you do decide to get an external SSD for booting your iMac, then once you get everything installed & migrated, then you should try secure erasing the internal Hard Drive to overwrite everything to destroy & protect the data that was stored on it. I believe Disk Utility for Ventura still has the "secure erase" option to write zeroes to the whole drive when you erase it (IIRC, this feature was removed in macOS 15.x Sequoia). For the internal 128GB SSD only a simple erase is needed to destroy the data on it. Since it is a 128GB SSD, you can use it for extra storage....just remember to include it in your backups if you do use it.
