relocation.
You can set the speed to: 1(Slowest), 2(Slower), 3(Standard), 4(Faster), and 5(Fastest). The
default is 3(Standard). If you want to perform tier relocation at high speed, use the 5(Fastest)
setting. If the speed specified is slower than 3(Standard), the data drive load is low when tier
relocation is performed.
