Selecting capacity tier disks

The magnetic disks or SSDs you choose will be used for storage capacity and persistent data that is destaged from cache. This is the capacity tier within VSAN, whereas the caching tier SSD will act as the performance caching layer.

In general, you will want to select magnetic disks or SSDs that have adequate capacity to fit your needs. For highly dynamic workloads where data will be frequently destaged from the SSD write buffer and fetched into the SSD read cache, HDD performance is important and you may wish to go with faster disks and/or SAS disks. Only SAS and SATA disks are supported for use with VSAN.
