I have MicroCloud system 5037MC-H8TRF with HDD performance drop issue. When the fan is set to standard speed, the performance is about 100Mb/s. But when the fan is set to full speed, HDD performance would drop to 9-10Mb/s. Do you know the problem? My HDD model is WD WD5000AAKX SATA3 500GB.
The HDD model you have is Desktop HDD, and the shock rating is only 30Gs/2ms; please change it to Enterprise HDD. Enterprise HDD will have better stability and shock rating than desktop HDD. Also, based on our test, Seagate HDD has better performance than WD HDD across different platforms.
