Time to breathe new life into a 5,1 MacPro. Currently it has 1x2TB drive for OS, and 3x 500GB drives in a 1.5TB SW RAID. Mainly used for After Effects. Planning to replace the system disk with a 1TB SSD, and possibly replace the raid with 2x1TB SSDs or 3x 500GB SSDs. Don't really need to go much over 1.5TB, as that would only stress the Time Capsule backups anyway. Any spare bay would house the old system disk, just in case. Any dos and don'ts? Recommendations? Will there be much benefit it replacing the drives in the RAID or will there be a bottleneck somewhere else?
