I do note that for all the reports here, people all seems to have SuperMicro
machines. I have a X10DAi motherboard, and it has a 'C610/X99 series chipset
6-Port SATA Controller' on the motherboard connecting to this disk. 

Interestingly, on this machine, I also have 2 other mps 'LSI 9207-4i4e PCIe
SATA Host Controller', and I also have another HUS722T2TALA604 on it. That disk
has been running for 5 months, and I have never seen any problems.
