      Excellent Hard Drive!

      I've been using Exos drives for the last 7 years and none have failed on me yet! I picked this one up on sale for $279.99. Exos drives are the most reliable I've ever owned and you can't beat a 16TB drive with a 5 year warranty for the price!

      Doing machine learning, which needs a lot of head room. This drive gives me all I need. Easy to install and fast as needed. Should last a while.

      Put four of these in a Synology RS1619xs+ and I get 42TB of useable space in RAID 5 with full 10 GbE download speeds and about 500 MB/s write speeds. I've written at least 70 TB over the course of 1,650 hours to the array so far and no hiccups or bad sectors. It of course takes a few years to find out how good these truly are but they are off to a great start. ST16000NM000J seems to be an updated version of Seagate's 16TB enterprise drives with a bit more sustained speed. I had some bad luck with the first generation of 12TB Ironwolf drives so I'm going to be sticking with Exos for the foreseeable future, plus they are actually less expensive in most cases.

      Did a lot of research from HDD review websites. This 16TB Exos X18 HDD seems to be the most reasonable choice for now (great price). Not regretting the purchase - with 5 years warranty and so far so good. It is working great on my Synology 918+.

      I use the drive to store large video files on my PC and was a little concerned when some people mentioned noise. I have written to and from this drive multiple times with no discernible noise from the drive. So far a solid drive at a good price.
