The performance impact of adding WD Red Pro 16TB disks to an SHR array with two Seagate Ironwolf Pro 16TB disks is hard to predict. Although it is generally better to have the same disks in an array, mixing hard disk manufacturers in an SHR array is possible as long as the drives have similar characteristics, such as capacity, rotational speed, and cache size.Thank you. If I already have two Seagate Ironwolf Pro 16TB disks in a Synology 920+, would it be a good idea to add two WD Red Pro 16TB disks to the SHR array? Or would it be better to get two more Seagate Ironwolf Pro 16TB disks?
How does differing cache size between disks in an SHR array affect performance?
It is generally recommended to use hard drives with the same speed in an SHR (Synology Hybrid RAID) array. If you mix hard drives with different speeds, the overall throughput of the array will be limited to the slowest hard drive. This may result in a performance bottleneck that could affect the performance of the whole array.
As for mixing hard disk manufacturers, it is generally fine to do so as long as the hard drives have similar characteristics such as capacity, rotational speed, and cache size. However, keep in mind that using hard drives from different manufacturers and models might also result in a slower overall performance compared to using identical drives in the array.
Additionally, it is recommended to use hard drives from reputable manufacturers to ensure the best possible reliability and performance.
