SSDs are very resilient and provide faster access to data.
SSD enablement results in several benefits:
Use VMFS datastores that are created on SSD storage devices to allocate space for ESXi host cache.
Use local SSDs for such features as Flash Read Cache and Virtual SAN.
Use of SSDs increases virtual machine consolidation ratio as SSDs can provide very high I/O throughput.
It supports identification of virtual SSD device by the guest operating system.
