SSD Healthcheck

[cambridge-pc-support]

Any recommendations for software to check the health of an SSD?

I'm currently using HDD Sentinel which will report the health as a percentage. But, I'm not 100% sure if it's a good guide.

So, for example, if it's reporting 80% health, would it need replacing?

I don't trust the manufacturers own software. Had a 2.5" Crucial SSD a few weeks back that reported 100% health in HDD Sentinel and Crucial's own diag software. But, the drive kept acting up, going slow, etc. I thought that SMART was supposed to log all of this kind of thing, but I guess not

CrytsalDiskInfo will give you a complete SMART report, however SMART is just an indication of the drive health. It is more geared toward physical issues such as relocated sectors, hours on time etc. But a lot of SSDs suffer from firmware issues which are generally not addressed in SMART. Best solution you can have....... make regular backups.

SSD health is most often reported by the SSD via a specific health attribute. It is usually calculated on the basis of the average number of P/E cycles, or percentage of rated TBW, or both. These numbers don't reflect the error rates that are reported in other attributes.

All SMART tools will get the same numbers from the SSD. The difference is in how they interpret them. Many tools will misinterpret these numbers because there is no official standard for SMART attribute reporting, only loose, unofficial conventions. Even the manufacturer's own tool will often get it wrong.
