关于spin up time的解释,分享：It's normal for these attributes to fluctuate.The drive takes time how long it takes to the platters to reach operating rpm.This time is converted to some kind of value (between 1 and 253) to be reported with other SMART values.The bigger the value,the better (usually).As long as this value is greater than threshold of that same attribute,it should be OK.The threshold is a constant value given by the manufacturer of the drive.It's normal for spin-up time to fluctuate because there's many variables:temperature,humidity,how long was the drive powered off,how high are the voltages form PSU when spinning up,etc.If the spin-up time continues to decrease steadily (not just fluctuating up and down),take precautions if the value is getting close to the threshold value.If the spin-up procedure takes too much time,it could imply the bearings,spindle motor and/or it's control chip are wearing out.I assume the threshold value is much lower than 117 (the current SMART value)?What SMART monitoring utility do you use?Does it show you the threshold values as well?SPIN UP TIME值有变动是很正常的,因为有很多因素影响：温度、湿度、硬盘停止工作后时间的长短、当SPINNINGUP的时候,组成供电器/单位的电压有多高（这个难翻译）,等等.如果SPIN UP时间持续减少（并非上下浮动）,并接近阈值,请做好预防措施.如果SPIN UP 花太多时间的话,可能意味着轴承、马达或控制芯片正在老化.那浮动的范围究竟是多少?时间从x秒到1x秒不等.依品牌型号不同而异.
