Specifics
Fairbs. In some respects the discussion is not relevant. As you say each implementation needs to be carefully looked at in context. SSD speed vs HDD speed is not necessarily relevant because the internal connection to the SSD may limit it's actually performance and transfer rates. The reality is you need to make sure you have enough IOPS and capacity for your applications needs. What Hybrid storage does is it virtualizes SSD resources and share them across applications that sit at rest on HDD. In that way it handles the performance of each application based on the specific real time need of the application in your business. You of course need to look at the total from a systems standpoint and ensure that it fits in your budget. Hybrid Systems are designed to give you up to 10 times the performance of traditional storage systems without increasing the raw $/GB (In general for systems over 25TB). In fact because they allow effective use of larger HDDs and have all inclusive SW they can have a TCO 75% less over three years than traditional systems. In starboard Storage's case we also have a unified SAN and NAS capability enduring that you can virtualize your SSD across more workloads for greater efficiency and all workloads on the HDD are virtualized as well into a single pool that can accept any size of hard drive without worrying about RAID group management.
