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.

Pros: Good solid drive for mass storage, with (at time of purchase) the most economical cost per TB.Cons: As an enterprise drive it’s louder than many consumer drives, also speed in single disk setups is only ok, but in raid (which is what it is for) it really shines.

It's crazy that this 18TB enterprise drive is going cheaper than some 12TB hdds, so it is a great buy.The hard drive comes delivered in a good, cushioned package (none of the "free-flying HDDs in Amazon boxes" horror stories you see posted online ).Read is a consistent 270MB/s, and write speeds via USB (from a SSD) are a consistent 265MB/s, so pretty impressive!Only just started using the drive, so can't comment on reliability, but it does have the enterprise 5yr warranty and advertised 2.5M hours MTBF, so should do well (just remember to always have your 3-2-1 backup rule and nothing to worry about).The hardest thing was to stop myself buying more HDDs.Edit: Found out that this drive is a OEM drive, so Seagate themselves do not provide any warranty.

Exos X18 18TB, selected as a large reliable mass storage disk. Unfortunately it was DOA. Got in touch with Scan and the suport was very helpfull and arranged for the retun of the disk for replacement.Obviously there was dissapointment on DOA and having to wait a week to receive a replacement.The drive: A week later I received the tested replacement, and all has been well withthe disk. I have read reviews that say that enterprise drives can be noisy in comparison to normal desktop drives, and this was a potential concern however totally unfounded.So far excellent drive reads/writes are ~230-270MBs, and the drive really is very quiet and will be very likely to considerr these for the next NAS. So hopefully it will prove reliable for years to come.
Seems fast, plenty large. As an Enterprise drive it seems more tuned for performance than noise levels, with lots of chunky buzzing seek noises. . . though I quite like that. Not getting too warm in the small and quite poorly ventilated case I'm using. Naturally you can't review the most important thing - reliability - unless it either fails in a short time or lasts for a very long one. So far so good. Price as purchased (on offer at £320) was much better than the nearest 18GB NAS/Red drive at more like £460 at the time of purchase.
Pros: Excellent drive, 16TB to play with. Nowhere near as noisy as people make out, my 2 are silent. Occasional flickering noise but barely audible. Nice fast transfer speeds, much faster than any other drive I own. I don't normally buy Seagate, but at the price, it was a no brainer.Well happy, will buy more if the price drops again.Can't comment on reliability, these are only days old.Cons: None.
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.
Bought four of these replacing the original 8TB drives of the internal Promise Pegasus R4i RAID enclosure for a MacPro (2019). Quiet enough to sit in the computer off the desk in our production studio environment. Fast and quiet. All good.
I bought the hard drive, 2 weeks ago, the first one did not work out the box, just like one of the reviews stated earlier BUT, Scan quickly sent DPD to pick up the hard drive and within a week I was replaced with a brand new replacement.It's early days but its working like a charm, it can be a little noisy but its not enough to distract or irratate you when your doing your work. Like all hard drives, if your installing into a PC your going to lose a little bit. So I actually have access to 16.3TB.I would deffinetely buy another two at some point later, to replace my other drives. My trade is a Creative (graphics, animation, illustration, motion graphics) and sometimes as a hobby a beat maker. So as projects and files get bigger, I need a bigger hard drive, ... MoreI bought the hard drive, 2 weeks ago, the first one did not work out the box, just like one of the reviews stated earlier BUT, Scan quickly sent DPD to pick up the hard drive and within a week I was replaced with a brand new replacement.It's early days but its working like a charm, it can be a little noisy but its not enough to distract or irratate you when your doing your work.
