Essentially they’re selling disks as “raid compatible”. This implies the disk will perform well under constant pressure: resilvering a raid disk of these sizes

Essentially they’re selling disks as “raid compatible”. This implies the disk will perform well under constant pressure: resilvering a raid disk of these sizes can easily take several days.
However, they have cut corners / optimized costs that assumes the drive is not under constant pressure, but rather mostly idle. What this implies is that they likely just have a hybrid magnetic/ssd backend, which is what the outrage is about.

- klodolph 7y agoWell, you’re right, but technically that makes it “hybrid SMR”.
