The Series 6 family of high-performance Adaptec Unified Serial (SATA/SAS) RAID controllers offers maximum performance, scalability and flexibility. With the enhanced bandwidth of its 6 Gb/s SAS2.0 interfaces and the PCIe Gen2 host connection it offers up to 60% higher sustained sequential throughput than previous generation controllers.
Based on PMC-Sierra's market-leading, multi-core SRC 8x6G RAID-on-Chip (RoC) the Adaptec RAID 6405 can deliver up to 2 GB/s sustained data transfer rate to the host. Peak performance is up to 4.8GB/s through the SAS 2.0 interfaces and 4.0GB/s through the PCIe Gen2 host interface. Using SAS expanders, it can connect up to 256 SATA/SAS.
The Adaptec RAID 6405 supports a broad range of operating systems, compatibility with more than 300 third-party devices, and full integration with Adaptec Storage Manager for centralized management of all Adaptec RAID controllers on the network.
Update to prior review
Pros: The other poster recommended a 40mm fan which was spot on for the size required, so thanks to that person / poster.
Cons: Why no fan included on the card when purchased I have NO IDEA!
Other Thoughts: Note: I did add a couple of Enermax 120mm fans to replace some older and louder Antec Stealth 120mm fans in my case.

Great Card, but NOT for SSD
Pros: Worked well with HD Velociraptor drives in RAID 0. No problems and worked well right out of the box.
Cons: Did not perform as expected with SSD in Raid 0.
Other Thoughts: if you need more standard ports for manual hard drives, don't hesitate to purchase, but if your thinking you need more 6GB ports for SSD, this card will not be able to give performance needed for SSD Raid

Great for mechanical hard drives
Pros: Assuming a proper cable is purchased, SATA III hard drives can connect at 6 Gbps.
Cons: Boot time - With card installed, takes about 30 seconds longer until logon screen appears.
Other Thoughts: I purchased the card to create a RAID5 array on an older PC using three Seagate 3TB hard drives (STBD3000100). 64 Kb stripe size, used default allocation unit size in Windows.

Adaptec. Adaptec never changes.
Pros: Adaptec's hardware is still of extremely high quality and their BIOS level array configuration is fantastic. Adaptec Storage Manager (their OS level utility) is Java-based and ugly, but it works without any fuss. SNMP and SMTP alerts are supported - but if you have a single system with an Adaptec controller, remember you will get alerts only as long as it is still running!
Cons: If you're going to use this in a workstation, or really anything that isn't a 1U server, a fan is REQUIRED. You will NOT be able to get by without active cooling. See my Other Thoughts section for help with this.
Other Thoughts: Yes, those are screw threads for a 40mm fan in the closeups of the heatsink! After much trial and error, I have confirmed them to be M2.5-0.45 machine screws. 8 or 10mm length pan-head screws should be sufficient depending on how recessed the screw holes are in your fan.
