I noticed while using HWiNFO that my SSD system drive's health is showing just 1%. I read that this percentage doesn't always indicate an immediate issue, as it's based on average values. However, I'm concerned after looking at the drive in CrystalDiskInfo, and I'm not sure how to interpret the details. Should I be worried about my drive's health? Am I facing imminent failure?

A 1% health rating suggests that your SSD is heavily worn out. While this doesn't always mean immediate failure, it’s a clear sign that you should back up your data and start considering a replacement. Heavy read/write operations or unexpected power loss could trigger a failure soon, so it's better to be safe!
Make sure your backup process is solid right now. It’s your best defense against any data loss if the drive fails unexpectedly.
You mentioned you’re out of spare blocks according to the image. This usually means the drive has reached its limits in terms of writes. NVMe drives don't fail like HDDs; they gradually degrade. Since all spare blocks are used up, it’s crucial to keep an eye on performance. Your drive might still function fine for a bit, but a replacement is wise if it’s in heavy use.
With B3 being 0, it looks like you hit the TBW (Terabytes Written) limit, but the drive might still be okay for now; just plan to swap it out when budget allows.
I checked Windows, and it shows close to the full 250GB limit, aside from a small 100MB reserved partition. So, seems like I’m at the limit they advertise.
