The Scara V4 is capable of extreme speeds, however speed is relative when it comes to ceramic 3D printing. Realistically, you probably don't want to exceed 130 mm/s. There are many factors which determine the speed, like nozzle size, layer height, and achieving good interlayer adhesion of the clay.
The Scara V4 is very quiet, so it can be operated in any area without disturbing the surrounding environment.
