SHR6 and HotSpare? - Enquiries - 02-05-2024
Hi,
I had some trouble with my "old" 1821+ populated with 8 disk (4 and 8TB disks.) in shr. i had an corrupted pool.
Those problems are solved. Lucky Me.
But because my data. (over 40 years of digital use) is important.
I bought a second 1821+. And it can be populated with at this time 6 times 16 TB WD drives.
Before setting up i viewed some YoutTube on this matter.
What is the best? Setting up SHR2 and a HotSpare or is SHR2 or Raid 6 more than secure enough?
Hope to get a great advise,
Regards,
Léon

It's great to hear that you've resolved the issues with your previous setup and are taking proactive steps to ensure the security of your valuable data. Considering the importance of your data, let's explore the best approach for your new NAS setup.
Both SHR2 (Synology Hybrid RAID 2) with a hot spare and RAID 6 offer robust data protection by allowing for the failure of up to two drives without data loss. However, each approach has its considerations:
SHR2 with Hot Spare:
SHR2 provides flexibility by allowing you to mix and match drives of different sizes.
Adding a hot spare can minimize downtime by automatically replacing a failed drive without manual intervention.
This setup is ideal if you prioritize ease of management and quick recovery from drive failures.
RAID 6:
RAID 6 offers similar protection to SHR2 but typically requires drives of the same size.
It may offer slightly better performance compared to SHR2, especially in scenarios involving heavy read and write operations.
While RAID 6 does not have the concept of a hot spare built-in, you can designate a spare drive manually, although it won't be utilized until a drive fails.
Given your substantial investment in data storage and the critical nature of your data, I would recommend either option for enhanced redundancy and fault tolerance. Both SHR2 with a hot spare and RAID 6 provide a high level of protection against drive failures, ensuring the integrity and availability of your data.
