Is it easy to check that out when you have the drive?
Bought an ultra cheap (classic sata) 3TB drive for redundancy, haven't hooked it up yet though, but I mean what about some magic raid with a handfull if them for low usage like backup? Maybe some 512/1TB ssd as cache on top of it if it's used more than a backup? I mean I don't even know if that exists.
Sorry if it's a stupid question but I grew up well before 1GB drives hit the market :-)
SMART (the internal drive self-check/monitoring system, exposes a number of statistics that can be read by software on the host machine) exposes a "power on hours" counter and a "power cycles" counter - a high count of either of those would indicate a drive that had been heavily used. Also worth looking at the "pending sector count" and "reallocated sector count", as increasing values of those is a pretty good early indication of failure
Excellent, thanks!
It is easy to get to these drive self reporting data, but reading it can be tricky.
For Windows there are GUI tools like https://crystalmark.info/en/software/crystaldiskinfo/, that make all those values understandable even for people without much computer background.
For Linux the story is a bit different. Most current desktop environments do carry some functionality to read the S.M.A.R.T. data from the drives and display these data to the user. The user then has to find a way to interprete these seeminly random numbers. For things like the amound of written data to a drive (relevant for SSD) you have to pull out a calculator. Maybe there are also easily unterstandable GUI tools for Linux, I just haven't found them.
Thanks!
