Conclusion:

The Adaptec 6805TQ with maxCache 2.0 feature would be taking the hybrid hard drives with a built-in solid state drive and a spindle drive and bringing it to the enterprise level. The 6805TQ is a lot more expensive than the 6805E card we reviewed earlier, but with maxCache 2.0 and the ability to support more RAID options and the addition of a RAID battery, the 6805TQ has everything one would expect to find on an enterprise server. We did see a speed increase between the 6805E and 6805TQ, and both were much faster than the on-board RAID options, but due to additional expense of each card, it is not likely that a general consumer would purchase either card unless you have a serious need for speed or a particular purpose intended for the machine such as rendering or as a data server. Though if you have the disposable income for the 6805E and two SSD drives for a two drive stripe, there is very little out there that would be able to compete. The 6805TQ is an enterprise I/O beast which intended for large amounts of data I/O in a business setting. We did enjoy setting up multiple arrays in our attempts to find the limits of the 6805TQ, but in our lab environment, we never seemed to find a limit outside of synthetic benchmarks. The Adaptec 6805TQ has been every bit a jaw dropping experience to see I/O scores this high. We would like to thank Western Digital for assisting us with a set of their enterprise HDDs to be used in these two RAID card reviews.
