Study covers millions of drive days over six years using 10 different drive models.

at the end mechanical drives have a higher tendency to fail.

interesting I'll have a read of that later.

not sure it's that clear cut.

While flash drives offer lower field replacement rates than hard disk drives, they have a significantly higher rate of problems that can impact the user, such as uncorrectable errors.

"Between 20 and 63 per cent of drives..." "Between 30 and 80 per cent of drives..."
How is that useful data? is it 20 or 63%? is it 30% or 80%. Might as well say between 1 and 100% of drives had issues!

I think it basically says: spinning drives fail more often but SSDs corrupt more data.
Corruption is always worse than failure.

Margins like that just make the results sound unreliable.

Glad I'm not the only one confused by that lol.
I won't pretend I FULLY understand the report, but the bits I do are pretty much what I knew anyway :/

It might be the different flash-based drives, e.g. one type had 20% and another 63%. In which case there's nothing wrong with those numbers.

I was just thinking that.
