Legit Reviews takes a 6Gbps SATA/SAS LSI RAID card for and spin and ends up with a lot of performance graphs.
Today I have LSI’s latest RAID card, the MegaRAID 9260-8i SAS 6Gbps controller. Featuring a compact PowerPC RAID-on-Chip controller, 512mb of DDR2 cache, a PCIe 2.0 x8 slot, and SAS/SATA 6Gbps connectivity, the 9260-8i is one well equipped RAID card. Marketing documentation boasts of maximum 2875MB/s reads and 1850MB/s writes through the 800MHz PowerPC LSISAS2108 ROC, well over three times the throughput limits of the ICH10R controller built into Intel’s desktop platforms.
