Pre-emptive Wear Leveling (PWL)
This Western Digital feature provides a solution for protecting the recording media
against mechanical wear. In cases where the drive is so busy with incoming
commands that it is forced to stay in a same cylinder position for a long time, the PWL
control engine initiates forced seeks so that disk lubricant maintains an even
distribution and does not become depleted. This feature ensures reliability for
applications that perform a high incidence of read/write operations at the same
physical location on the disk.

- Abgesehen vom Klacken relativ leise im Betrieb

- Seitliches mittleres Befestigungsloch fehlt
Do you need frequent write performance, https://stickmanhookgame.org or mostly long-term archiving? If the latter, HC550’s high capacity and endurance may be ideal; for frequent random writes, a faster SSD or hybrid setup might perform better.
