PCI Express SATA RAID Controllers For SMB Servers

Enhanced RAID6

Enhanced RAID 6 works with triple redundancy. This might make sense for 8 and 12-port controllers, but certainly not for this quad-port model...

Test Methodology

We used four Western Digital WD1500 Raptor hard drives to test the controllers with four different I/O workload profiles : File server, web server, database and workstation. All drives were used to setup a RAID 0, RAID 0+1 and lastly a RAID 5 array. At the end of our testing we removed one hard drive from the RAID 5 and repeated the benchmark runs to see how the controllers would perform when the RAID 5 arrays runs degraded.

    This is a very well put together article! It would be nice if there was a review with recent RAID cards while doing the same thing you did here.
