Preventive Wear Leveling

[nockdown]

Which WD SATA hard disk model lines (Green, Blue, Black, Red, Purple, Gold) have PWL - “Preventive Wear Leveling”? I’m talking about modern models.

> PWL - “Preventive Wear Leveling”. It’s a periodic head sweep to distribute lubricant and prevent wear in a particular place if lubricant were to build up in one spot. On many older models, this would happen maybe once a minute. But on some builds it’s maybe every 5 seconds.
