Those in the know, know how useless this is. 3 drives implies RAID5, which with modern drive capacities is worthless. It’s a pretty fire extinguisher that gives you a false sense of security because the day you go to use it it only squirts out 3 seconds of plain air.
It has to do with MTBF and drives that are over around 1TB or so. When one drive fails and you go to replace it, you get a read failure while it’s trying to resilver the new drive. But now you have no redundancy so POOF goes your data.
In 2018… and for some time now… it’s RAID6 (or RAIDZ2) or don’t bother wasting your money.

They don't die. Just Quick-NAP.

Thank you!
