IOPS-energy-efficient characteristics, SSDs have the potential to allow your storage
infrastructure to achieve significant savings in operational costs. However, the current
acquisition cost per GB for SSDs is currently much higher than for HDDs. SSD performance
depends a lot on workload characteristics, so SSDs need to be used with HDDs. It is critical
to choose the right mix of drives ...
