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.

In the last few years RAID has become really quite popular. Once purely in the domain of high-end enterprise servers, today, any self respecting enthusiast motherboard had better have onboard RAID if it wants to be taken seriously. The abundance of onboard RAID controllers mean that it’s not unusual to see small arrays in today’s home computers. The reasons for this can be for increased speed, increased reliability or simply for bragging rights. After all, two or more disks are better than one, right?
