HDD Management

This section allows you to monitor the status of the hard disks installed on your DiskStation, providing options to manage and analyze hard disk performance and health.

Enable Write Cache Support for Hard Disks

Enabling write cache support enhances the performance of your DiskStation. Only certain hard disk models support this feature. To ensure data protection while using write cache support, usage of a UPS device is strongly recommended. We also suggest the system be shut down properly every time after use. Disabling write cache will reduce the chances of data loss caused by abnormal power outages, but system performance will decline.

To enable write cache support for your disk:

  1. Select a disk and click Cache Management.
  2. Tick Enable write cache. By default, this function is enabled.
  3. Click OK.
