The MegaRAID SAS 9271-8i 6Gb/s SAS and SATA RAID controller card is designed to meet the needs for capacity, performance and data protection in data center, cloud and high-performance computing environments. This card is powered by the LSI SAS 2208 RAID on Chip (RoC) controller, and features two 800MHz PowerPC processor cores and a 72-bit DDRIII interface that drives 1GB cache memory. And with eight internal ports, the 9271-8i controller includes the latest PCI Express 3.0 and 6Gb/s SAS technology for unmatched RAID performance.
Pros: absurdly fast, tech support is very on-point, has low profile bracket. Drivers and firmware are straightforward and well supported across the board. used in multiple builds with SSD arrays (Samsung 840 Pro and Mushkin Chronos Deluxe), no problems, throughput is off the chart.
Cons: It needs on-board cooling, no exception. The card overheats in a workstation chassis. You MUST MUST have a high CFM PCI slot cooling fan just under this card to avoid overheat. You can never have enough airflow over this card. cant stress that enough.
Overall Review: Aside from the cooling issue, its the best card out there. The BBU and FlashCache are pricey though.
