> I would guess WD is putting a user accessible CPU in each of their disk drives, idea being that if you have a CPU living close to the drive, then e.g. map+reduce workloads can be more efficiently executed.
I don't see how this would be better than our current systems architecture. Is the interconnect between the disk drive and the main CPU/memory really the bottleneck?
Even if the CPU lives inside the disk drive case, it would still be limited by the same read/write speeds as a CPU 20cm away.
