Can you RAID 1 with different size drives?

If different sized hard drives must be used, the total capacity will be bound by the disk of the smallest size in the group. In a RAID 1 configuration, the size of target disk must be greater or equal to the one of the source disk.

Can synology use different size drives?

Synology does allow you to mix different make and size drives.

Do all NAS drives need to be the same size?

Some NAS units absolutely require drives to be identically sized. If it is only capable of presenting one Volume to the network, this is good because dissimilar drives create wasted space. More advanced NAS units can present multiple Volumes, so you can deal with have sets of differently sized drives.

Can RAID 5 drives be different sizes?

You can use RAID 5 with different sized disks physically, but within the RAID features they all have to be identicle. What would happen in your case if you configured a RAID5 with all 6 disks, is that the RAID would use 6 x 2TB leaving the four 4TB drives with 2TB of free space.

Is Shr the same as RAID 1?

Unlike classic RAID, SHR divides each drive’s storage space into smaller chunks and creates additional redundant storage. Using the same example as before, SHR is able to divide the 4.5 TB of unavailable storage into smaller usable chunks and maximize the storage capacity of each drive.

Can I mix HDD in NAS?

If you are not creating RAID but have two separate volumes for each drive, then you can benefit from maximums speed from the black drive or pro drive. But yes, you can mix drives.

Do RAID 1 drives need identical?

Must hard drives in a RAID array be identical? No. It is perfectly valid to use hard drives from different manufacturers, model numbers, sizes, and rotational speed (spindle speed or RPM).

What’s the difference between Synology raid and SHR?

SHR made up of dissimilar capacity drives provides a much bigger amount of usable storage space when compared to RAID – only one largest drive is “lost” for redundancy; even so, Synology RAID guarantees protection against one failed drive and the subsequent data loss (with SHR 2 – even two disk failures);

Is there a raid calculator for Synology NAS?

Notes: Visit here for more information on choosing the correct HDD for your Synology NAS. Synology RAID Calculator offers you an estimate on the space utilization with various mixed HDD configurations and RAID types. When using SHR or SHR-2 HDD protection as your RAID type, the Unused space will be automatically reserved for future expansion.

How big is a HDD on a Synology NAS?

The actual HDD size will be affected by the system partition and can vary between vendors, so the values calculated may differ from the actual results. Please refer to Synology Storage Manager for precise data calculations for storage installed on your Synology NAS.

Is there a single volume limit for Synology?

Some models can support larger single volume capacities after upgrading the installed memory capacity. To find out more, please refer to Why does my Synology NAS have a single volume size limitation of 16, 108, or 200 TB? Synology RAID Calculator makes recommendations based on the total capacity picked.
