The 3ware SAS 9750-16i4e controller card provides a new level of system reliability, availability, and performance for businesses that are facing storage challenges driven by unprecedented data growth. Offering data transfer rates of up to 6Gb/s per port, this controller card ensures complete investment protection for existing SATA and SAS implementations. 6Gb/s SAS is designed for backward compatibility with 3Gb/s SAS as well as with 3Gb/s SATA hard drives. In addition to the internal ports, this controller comes equipped with external SAS ports which perfectly support external JBOD expansion, allowing you to connect multiple JBODs to server for a scalable and affordable solution to the growing storage requirements. Regardless of the drive speed, 6Gb/s 3ware SAS 9750-16i4e can deliver up to twice the performance level in both read and write applications as compared to their 3Gb/s predecessors.
Pros: It didn't catch fire.
Cons: I am aghast at this controller. I can only assume I had a faulty unit. It seemed to work fine for a while but then we had inexplicable slow-downs in RAID5 performance. I'm talking 3-5 MB/s. Then it started failing drives. I upgraded the firmware on it and looked at all the alarms it had to offer and there was nothing new. I ended up losing a RAID5 volume as it failed a drive when the LUN was already down a drive.
