My physical disks can hit 165+MBps on reads, so when moving large video projects and photo collections off the array, it’s 50% faster. Then on the way back, it hits 400+MBps to the ssd cache, making it 3-4x faster. Eventually I’ll go raid 10 on the cache and it should hit 600MBps. Or maybe I’ll go nvme and try to saturate the connection (if I can free up a pcie slot).
its not really something everyone needs. If you only move 1-3GB, it’s not really worth it. But with 200GB video project files, it helps save some real time.
(but it is fun to play around with)
