Seagate Exos X20 18TB 7200 RPM 512e SATA 6Gb s 3 5 Enterprise Hard Drive - ST18000NM003D Renewed

Very nice drive for the price. I was a bit hesitant to purchase a refurbished HDD but seeing as it was refurbished by the OEM (Seagate), I figured it should be ok as I have purchased other OEM refurbished products without any problems. When the drive arrived, I witnessed the post person just give the delivery box a good toss (about 6 foot) onto my cement stoop, landing with a loud thud. I was a bit taken back but my neighbor also witnessed it, so I figured if there was a problem, I'll have some backup if it were to come to that. Opened the outer box to find a Seagate inner box containing the drive in a suspended shipping cradle (of sorts). No dings like I saw on one of the reviews on Amazon, thank goodness. Hooked the drive up to an external SATA interface and connected it to my desktop PC. Fired up my copy of SeaTools (SeaGate utility) and ran the extended test and everything passed A-OK. It did appear the S.M.A.R.T. data had been wiped as expected if being refurbished. Only showed 2 hours of power on time (probably from testing after refurbishing. Ran another intensive bad sector surface scan using AOMEI Partition Assistant and passed OK. Mounted the drive in a Synology DS224+ to act as backup target in a NAS-to-NAS auto-backup. Once installed and configured, worked A-OK. So far it has operated flawlessly but it's only been a few days. The drive is a bit noisier than some 16TB Synology (rebrand Toshiba) drive I have in use. Best I can tell this drive meet its indicated specs. Read more

Update 2 Days Later: I forgot! Notice, as you read, that these drives are, therefore, completely compatible with Asustor and Synology NAS's, even though you might get warned that they're "not on the list". They work perfectly. I've got 4 NAS', two four bay Asustors, a two bay Asustor, and a four bay Synology. There might be an Iron Wolf or two in them, but they're pretty much all renewed EXOS hard drives nowadays. The Synology had the smallest drives - Four 10TB EXOS drives. I got these 18TB drives at what I consider an extremely good price. After thinking about it for awhile, I came up with what I thought was the logical thing to do. (all this one drive at a time, of course.) I took two of the 10TB drives out of the Synology and set them aside. I took the two 14TB drives out of the Austor two bay and put them in the Synology. I did that because the Synology has that SHR (Synology Hybrid RAID) option; it does better with different size drives, as far as using all the drive space. Now it has two 10TB and two 14 TB drives. Then I put these two 18TB drives in the Asustor two bay NAS. It's got a two drive RAID where the drives simply mirror each other for data redundancy. (One of the disadvantages of a 2 bay NAS.) The Synology has an SHR with one drive fault tolerance. So every drive I touched for this swap was an EXOS; NOT an Iron Wolf. Everything totally good to go!! (After about 60 hours.) These drives were very well wrapped in several layers of bubble wrap. They got here VERY quickly (-two days!-) from across the country. The have new white stickers on them, that you'd swear were the original stickers until you see that they say, "Renewed". There's all that Seagate stuff: They're helium filled, making them more efficient because the platters can spin more freely than if there were air in there. Because they're helium filled, they logically have to be completely air tight or the helium could get out and be replaced by air. Their mean time between fails is listed as 2.5 million hours. They're SATA 6, which I need. All those NAS' are 2.5 GB Ethernet except the Synology, which is only dual gigabit. Sure don't want a big SATA bottleneck. As it is, the drives, themselves, all transfer between 190 and 200 megs per second. I couldn't care less about the noise, but you couldn't call them loud; you can hear them. If that bothered me, I would just move the NAS'. What stunned me the most was the enclosed warranty card!! Who does that?!? I scanned it. I can't come up with a down side! Other than, even at a screaming price, it's still quite expensive to outfit an NAS. That's just life. All I ask is that, once I'm done, I'm all set. And I pretty much expect all these drives to outlive me; I don't run a busy office or a data center. If I don't experience a severe earthquake or a fire, I'm good!! My stuff is safe! Even if an NAS blows up! Because I tend to put all my stuff on more than one of them. Love these drives! And love the rich guys who are getting rid of them for whatever reason! Maybe they're all upgrading to 20TB SSD's? Read more

Woring just fine in my Asustor NAS! Delivery was quick too. Read more

First drive was bad, didn't spin up. Waiting on replacement Read more

I needed to update my NAS set up and needed to start off with some decent, reliable drives. It came in and has been working great for about a week without issue. I got a reurb unit an I know sometimes harddrives can be hit/miss, but so far thsi is exactly what I needed at a very decent price. If it continues to hold up well through this migration I'm sure I will get additional drives for some of my remaining bays. Read more

Bought two of these for a server. Items came in pristine condition and are working well. Read more

First one was defective. We'll see about the replacement Read more

I have purchased many a Seagate drive over the years and have had a problem with only one. So remember, Back Up! The only reason I keep buying more of them is they keep getting larger and cheaper. Especially when a renewed one is bought. The first one I bought was in 1994 was 1GB and cost $600. Now this one is 18TB for $200. That is 18,000 times larger. Or, as I like to bore my kids with is in 1994 18TB would've cost 10.8 million dollars and taken up a small room kept at 68 degrees. Read more
