Note the missing information on performance, hard error rate, seek time, etc. If you are not willing to clearly compare the drives so that people can estimate performance, reliability and the time it is going take to rebuild a RAID set, I would like to suggest the drive is not ready for the enterprise.
At 6 TB in size declustered RAID is going to be required, and without the performance data it is a paper tiger as far as I am concerned.
