I am looking for a laptop to replace my current desktop. Availability and data redundancy are a concern for me, so I would prefer a minimum of dual 2TB drives running Raid 1. I do not mind adding a second drive to the system, but it concerns me that the manufactures are not clear as to whether Raid support is available. Does anyone have any recommendations or experience with this configuration. I would prefer a 17" screen. Blu-ray writer would be nice, but it is ok if I use an external drive.
