4 such hard drives are linked in RAID5 with all the consequences. The final speed (SATA2 ports) of serial recording is at least 50 mb / s (I wonโt talk about the difference between megabytes and megabits). Unloaded temperature (basket total) 28 C. Most likely, the controller is to blame, but sometimes the hard drives in the BIOS are determined for 5-10 seconds and after that they have crooked names in the same place. One of them after 1.5 years RAID marked as dead. SMART does not seem to swear. I will dig why.
