Slow rebuild speeds with JMicron HW RAID Manager
Table of Contents
If you are seeing slow rebuild speeds with your High-Rely BNAS unit and JMicron, please considering the following:
- The AMT board inside the BNAS is rated for rebuild speeds of 350-600 GB/HR. With newer larger capacity drives, you could see rebuild times of over 24 hours. The BNAS uses block level copying, it will mirror the entire disk whether there is data written or not
- High-Rely recommends spacing out your backups that are being written to the RAID so they are not occurring at the same time as a rebuild. we recommend this as to not interfere with the rebuild speeds, as well as making sure the BNAS is copying the most recent data to the RAID set.
If you believe you are still seeing slower than normal rebuild speeds, please contact technical support for further assistance.
