Question ssd drive health

Weird that it doesn't show total host reads, although that's only useful for telling if it was a write-intensive or read-intensive drive. That could be due to the USB enclosure not passing all the data but that would also be odd.

The health is based on several factors like the number of host writes, reallocations, wear leveling, errors, etc.99% is fine for 1.5 years, but I wonder why it isn't 100% as the numbers look damn near brand new, like a car that only has the test-drive miles on it. Perhaps the power-on hours is significant enough to account for it. My 1TB WD SN850X is at 98% after 1.4 years, but I've written 33658GB. The drive you're looking at has only had 4110GB written. The two have equivalent TBW ratings (600 vs 2400) given the sizes, so yours has had basically nothing written to it and should functionally be perfect.

I would kind of be concerned about those numbers. Where are you getting this drive? It's possible that it was much more heavily used and someone reset the SMART data to make it look like it's new, although the power on hours count would make that less likely. It's just very odd to see a drive that was actively running for 1.3 years and had virtually nothing stored on it. Did they just fill the drive up and then let it sit there with no data being changed, just being used for reads?
