I know the throughput of a standard HDD doesn't quite saturate a 6Gb/s connection (if someone has a numerical value, that would be great). I have been told that the only way to reasonably saturate this is to put some SSDs in a RAID. How true is this?
EDIT When designing a configuration, what are good reference numbers (MB/s) to associate various HDDs and SSDs with (7200 rpm, 10000rpm; MLC, TLC, SLC)? When looking on a site such as NewEgg, there is no real speed listed, just the compatible SATA Ports (SATA III 6Gb/s)
