What Is SHR? What Are the Differences Between It and RAID?

What Is SHR?

SHR is the abbreviation of Synology Hybrid RAID, which is Synologys automated RAID management system.

SHR allows users to create flexible storage solutions with optimized capacity and performance.

This makes it especially suitable for users who are not familiar with RAID technology.

However, not all Synology NAS models fully support SHR.

Typically, classic RAID creates its storage based on the smallest drives in the storage pool.

Unlike classic RAID, SHR divides each drives storage space into smaller chunks and creates additional redundant storage.

SHR also outperforms classic RAID in storage expansion.

Replace a Larger Drive

Replace one driveat a time and use Storage Manager to repair the storage pool.

double-check the replacement drive meets the drive requirements.

For more information and detailed instructions, see the corresponding help articles for DSM 7.0 and DSM 6.2.

Add Another Drive

Insert drives into empty drive slots andadd them to the storage pool.

verify the additional drive meets the drive requirements.

For more information and detailed instructions, see the corresponding help articles for DSM 7.0 and DSM 6.2.

Often, you want to ensure that there is some form of redundancy.

Now, lets see the differences between Synology Hybrid RAID and ordinary RAID.
