I currently have this system. It is configured with RAID6 using 750 GB drives (I got it before the 1 TB drives were released). I have it setup as two actual drive letters (D with about 683 GB, and then E with the rest...about 8.87 TB). Anyway, I am seeking options to replace it. The reason is because the SCSI interface it uses is very slow when transferring from one of the system's drives to the other. The system is also extremely heavy. I'd like to get something with less weight if possible. However, the main thing is a better interface. I am thinking eSata. Do you all have any recommendations on a solution to meet this requirement? I am looking to have the same or more disk space.
