The biggest delay in Intel® RAID Expander performance is the RAID card waiting for a hard drive to retrieve information.
How does the 4-port Intel® RAID Controller perform?
With a single x4 connector (4-port Intel® RAID Controller card):
- You can have three more commands going to three other drives, while waiting for the first drive to come back with the data.
How does the 8-port Intel® RAID Controller card perform?
With dual x4 connectors (8-port Intel® RAID Controller card):
- You can have seven more commands going to seven other drives, while waiting for the first drive to come back with the data.
When comparing the 4-port Intel® RAID Controller or one 8-port RAID Controller card, which one provides better performance when using an Intel® RAID Expander?
The 8-port setup provides better performance.
