I don't understand why these are not used more than WD. The MTBF is higher, the duty cycle is higher and the price is cheaper. The sound difference, if any, doesn't matter. B&H came through after I received wrong drives from Amazon. Its the best bang for the buck if you have a NAS.

This drive is fast and quiet. Something I can definitely can get used to. And power savings. Yes, lets bring up the fact this drive replaces four 4TB drives and I am seeing my electricity usage decrease. Only 5 more and I can power off my remaining 4TB drives. They can always be there for a cold backup which I can do once a week on Saturdays.

Bought 2 of these for a NAS I put together. I bought them for capacity, Price and reliability. Did some research found these to be well reviewed. the only gripe I have is they call it 8TB but its actually 7.2. Which where I went to school and learned math. When rounding numbers this would be called a 7TB not 8TB. If it were 7.8 or something remotely close Id understand. But not 7.2 Shame on you Seagate. Now for the good. These have 0.35 percent Annual failure rate. which is one of the lowest for enterprise drives. These are cheaper than their newest line of Ironwolf drives. Considerably cheaper in fact. These have a 5 yr warranty where the Ironwolf only have 3 yr. these drives are rated at 500TB per yr. usage where the Ironwolf are rated at 300TB per yr. You do the ... MoreBought 2 of these for a NAS I put together. I bought them for capacity, Price and reliability.

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.
I've had it for a few months now and it has functioned flawlessly. Nothing to complain about except that you lose quite a bit of space due to the overheads but I guess that will be the case for any HDD of this size. Will probably get another one eventually.
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+.
Used for a DS 1821+, its only been a week but they seem to working great. They are quieter then I was expecting. Also they run fairly cool and that was nice to see as well since our rooms tend to run a little warm. I have seen some people talk about seagate drives and a high failure rate but I have never had a problem with any that were from Thailand. I have 8 of the 18tb, 10 of the 10tb, 2 of the 16tb, and 7 of the 4tb that are older than i can remember and still keep running. All are enterprise class drives. Zero failures for all the above. All the above are from Seagate Thailand manufacturing. Seagate should take notice of this fact.
From as far back as S.M.A.R.T. was designed into hard drives, when i checked its stats in Seagate disks i saw very high error rates and very high seek error rates even in brand-new ones. These 18TBs are no exception. They make me deeply regret having bought 5 Toshiba 18TB and 5 Exos. Now i know it should have been 10 Toshiba's. Its officially the last time i buy Seagate whatever the name of the product line. They make one wonder how long before they lose it.
I purchased this for my Mac Pro 2012. It ran great for about a year then failed. Smart said it was OK but it was the boot drive and it failed. Cant format it either. I always loved Seagate. But I will try western Digital now. No reason to fail in todays age. It is under warranty. But last time i sent in under warranty i got a "Refurbished drive that broke in 6 months" so I will try Western Digital or Toshiba now. first time in years i had a HD fail.This is NOT a Enterprise Drive. Enterprise don't fail in a year and have problems. I love OWC they always make it right. Not OWC's fault Seagate drives are made to fail. Seagate has turned into a Walmart HD not a quality drive. Apple never used them and I know why now. Big hassles when Macintosh HD boot drive fails.
I selected this drive as the 16TB seemed less reliable in tests and is barely cheaper. Moreover, I wanted the ability to replace on failure. That is where the 5 year warranty comes in. Some third party vendors resell OEM drives that lack this warranty or US origin sales. My experience is that of they fail it is the first 3 months. Once you pass that hurdle, you are typically fine. Please ensure you back up your files.One word of caution, duplicating a smaller drive and enlarging the image size may bump you into partition size limitations in Windows, resulting in unused disk space. That is fixible with third party software, but cumbersome and introduces the risk of data corruption. Instead format this disk and copy the content.I have multiple brands of harddisk ... MoreI selected this drive as the 16TB seemed less reliable in tests and is barely cheaper.

So far 62TB of Seagate storage without problems.
