  • Dependable drives with lots of bang for the buck
Pattern: Bare Drive
As of spring 2018, the Seagate Exos 7E8 ST8000NM0055 8TB drives are the best bang for the buck in terms of $/TB and features though the 10TB version is not far behind on the price front. I compared this enterprise grade drive to both Seagate's consumer line equivalents (Barracuda Pro/Ironwolf/Ironwolf Pro) and similar offerings from rival brands (HGST and WD) and this drive is compelling in many ways: 1) It has the largest cache at 256MB while many competitors offer only 128MB cache on similar drives 2) Unlike consumer NAS drives, it is rated at 7200rpm instead of the slower 5400rpm which means it's noticeably faster than the Seagate ST4000VN000 NAS drives that I run in my QNAP 3) It actually surpasses consumer grade NAS drives in terms of both annual write load (~500TB vs. ~300TB) and MTF (~ 2million vs. ~1million) 4) Since it is an enterprise grade drive it is designed for always-on workloads and is suited for high-vibration environments such as in server racks 5) Unlike many consumer grade drives, these drives actually come with a full 5 year warranty (more on that later). However there are also a few (not many) cons: 1) This drive is a bit noisy. All my drives have the SN04 firmware which resolves many of the noise complaints reported on here about clicking sounds, etc present on the same drives with earlier firmware. But this drive is still louder than many consumer grade drives, especially the ones rated for lower rpms. It can seem a bit alarming, but none of my drive diagnostics turn up any problems and it's not drastically louder to be annoying next to my desk. 2) These drives seem to run a bit hot. I suspect that they are specced to run a bit hot anyway since they are designed for enterprise data center environments but I'd still advise beefier cooling solutions. I replaced stock fans on my enclosures with higher grade Noctua fans and they seem happy so far. Overall, I am very happy with these drives and have 8 of them running on 2 separate arrays with no problems. They are fast, reliable (so far), and seem to be very robust. Finally, regarding warranties, there are reports on Amazon of some third party sellers selling OEM drives that may have been pulled from actual server units and thus do not come with valid warranties from Seagate. While it is true that these drives are usually OEM drives, Seagate does sell OEM drives that come with valid end-user warranties serviced directly through Seagate so just because they are OEM doesn't mean they won't come with a warranty. It all depends on the seller and where they sourced their products. I got all 8 of my drives through SabrePC and they told me all their new drives are under warranty. The drives' S/N all checked out on Seagate's website as having valid 5 year warranties when I got them. As a plus, SabrePC is usually the cheapest price anyway. So no complaints from me on that front. Their customer service is also very responsive if you call them with questions. ... show more

  • Over time, these have been a solid performer
Pattern: Bare Drive
I use these in a Synology NAS. I use nine of these in a RAID 6 configuration in two volumes. I store everything from archive data to security footage. Over the past 7 years, I have never had a complete failure. I have had a few instances that Synology Server reports an increase in bad sectors. When that occurs I have been able to return the drive to Seagate and received a replacement with no hassle. This has occurred maybe 3 three times. Fortunately, these issues occurred in warranty. I do keep an extra drive handy in case I get a failure, but I feel pretty good with RAID 6 and the reliability of these drives. All in all, this has been a solid drive, and Seagate has been good at solving any issues quickly. ... show more

  • Sold as NEW and has NO WARRANTY with Seagate!!! BEWARE!!!!!

Be aware of NEW Drives! I purchased through amazon, vendor ended up being ONLINE USA OUTLET and being charged for a new drive. Registered with Seagate and then checked the warranty. Purchased 7/21/2026 and the warranty EXPIRED on Sept 9 2023! This should not be allowed to be sold as new unless it really is new. Amazon has no way of reporting this FRAUD! ... show more

  • Great drives
Pattern: Bare Drive
I've had six of these drives running 24/7 in my home server for a little over two years, with no problems at all. I'd been using consumer-grade drives before then, and had occasional problems, which I wanted to avoid. They're a little noisy, but that's to be expected for enterprise drives; they're designed to be in datacenters where noise isn't a concern. The warranty on these is awesome, and I'll definitely buy more when I fill these up. ... show more

  • Great product and customer satisfaction
Pattern: Bare Drive
Very pleased with this find. Too many times on Amazon I've found "new" enterprise storage disks that come with scrapes on the sides with DOM showing 6+ years ago. Not only did the 8 that I received from this seller show up nearly sequential in serial numbers, but the devices were actually brand new in the original static bags. Additionally, a friendly card with the stated S/Ns was included indicating a hassle-free, 5-year replacement warranty. Will definitely be buying from these folks from now on! Cheers. ... show more

  • Great after firmware update but runs hot
Pattern: Bare Drive
Great drive, 550TB/year with 2 million hours MTBF and 5 year warranty at a great price. These are older models and some still come with the old SN02 firmware. Mine came with that version and it was making a terrible buzzing noise when idle. I downloaded the firmware from Seagate and updated it to the latest SN05 and it's like a different drive, the noises are gone so I'm happy. Updating the firmware is a bit convoluted since you have to input your drive's serial number in Seagate's site to find your download, then you have to run the Seagate tool using command line and then run some commands. There are several guides on youTube for that, just follow them and you should be ok. The drive's been running 24/7 for a week on my home server and so far so good the only thing that worries me is that it runs hot, currently at 51C while my other HGST installed in the same machine is running at 42C but that one is helium filled so probably not a good comparison. The max operating temperature is 60C so we'll see in the summer how it does and hopefully it lasts. ... show more

  • It works and is brand new - that's all that matters!
Pattern: Bare Drive
I got this when my year old Ironwolf drive unexpectedly failed, and it dropped right in and works perfectly as expected. Also nice to see from the internal hardware stats that is really is a new drive too. I've had good luck with most of the Seagate 8TB drives I've had, better than with 10TB or even 4TB sometimes. Highly recommended! ... show more

  • Performance and warranty at a good price
Pattern: Bare Drive
I'm really impressed with this HDD so far and Seagate service. I did verify that this HDD was new and the warranty was valid, even though it was 8 months short because Seagate warrants by vendor purchase date but I called Seagate support and after verifying my purchase, they happily extended my warranty to the full 5 years. I've been purchasing HDD's for about 15 years now and I've had good luck with Seagates even though a few might say otherwise. I always purchase a good power supply and make sure I have a good PC case that keeps my components cool and secured. The only negative so far is that it's a slight bit noisier than my slower 4TB NAS Seagate HDD's, though bearable, it's the cost we pay for more HDD performance. I'll try to update in a few years. ... show more
