The SSD Review published a review on the Adaptec (by PMC) ASR-8885 12Gb/s PCIe RAID Adapter
A quote from the article:
The Series 8 gives us the best of both worlds; high port count (16) and high port bandwidth (12Gbps). There are actually 5 different adapters in the Series 8 family. The first is the ASR-81605ZQ which has 16 internal ports with integrated Zero Maintenance Cache Protection. Next we have the ASR-8885 and ASR-8885Q. Both have 8 internal and 8 external ports, with the 8885Q coming with the AFM-700 flash-based cache protection module. Adaptec also has the ASR-8805, which has only 8 internal ports. Finally, the ASR-8885E, which is identical to the ASR-8885, but only has 512MB of cache protection, versus 1024MB for all other flavors. It also only supports RAID levels 0, 1, 1E and 10, which might be a deal breaker for many. All other version support RAID levels 0, 1, 1E, 5, 6, 10, 50, 50 and 60. The ASR-8885 lists for $725, while the ASR-8805 is $640. The bargain of the group is the ASR-8885E, which lists for just $440.Adaptec (by PMC) ASR-8885 12Gb/s PCIe RAID Adapter Review @ The SSD Review
