Satisfied with speed and quietness of drive

I have only used my 18TB drive (WD181KRYZ-01CMFB0) for a few months now. I am happy with its performance to date in my FreeBSD system. It is quieter than a few of my other WDC gold drives. I have been a satisfied user WDC's gold drives for 20+ years now. I currently have several WDC gold drives in my systems, varying in size from 1TB to 18TB. They seem to last approx. 15 yrs for me.

No Complaints

I use this drive solely for data storage which it works great for that, I had a problem with the order and WD gave me a 15% discount which made the deal very good for me. Drive reads/writes around 250mb/sec so not bad for this type of drive. some minor noises now and then but nothing bad.
