IronWolf 16TB NAS Internal Hard Drive HDD – CMR 3.5 Inch SATA 6GB/S 7200 RPM 256MB Cache for Raid Network Attached Storage, with Rescue Service (ST16000VN001)

Bought 4 of these drives for a NAS I put in at home, these drives are top quality. Drives worked perfectly, fit the trays well and seated in just fine. Drives are relatively quiet for HDDs and are even more so in an enclosure. Speed, data transfer, formatting, all work great. Great value and quality construction, I have and will continue to recommend this product.

First one sent was defective (the first in about last 30 I bought). Not a problem, defects occur. What was great is that amazon got a replacement to me in only two days! Outstanding service amazon!

I purchased this Seagate IronWolf 16TB NAS drive from this Seller off Amazon. The Seller was originally listed as Maestro Technologies and later changed its name to CoreX. At the time the Seller had a good rating, and I thought I was making a good decision. The product was advertised with a three-year warranty. The product failed within the third year, and I requested a refund or replacement from the Seller. That's when the story unravelled in an unexpected way. Firstly, the Seller refused to refund based on its own warranty period being 1-year. The Seller informed me to contact Seagate directly. Which I did. Seagate then took the serial number of the product and informed me that this unit was a "grey" product. Meaning the product was not meant for sale within my region being the USA. Even though the product was still validly in its warranty period they could not replace it because it was considered a "grey" product. The "Beware" part. Seagate themselves recommend the Amazon platform as a Reseller. The product was a genuine Seagate product with a legitimate warranty. The Seller on Amazon had a good rating at the time. Yet still the warranty as advertised was not worth anything. My advice would be to not purchase this type of product off Amazon and to stick to reputable specialist resellers. Register the product immediately after purchase and confirm with the OEM that the serial numbers are valid for you region and the full warranty period.

I've gone through three 8 TB Iron Wolf HDDs, and they last for many years, very heavy rebuild after rebuild after rebuild. Those 8 TB are open to air, and the 16 TB are helium sealed, which is less friction and cooler. I have a NAS populated with 8 TB's, and am replacing with 14 TB's in a RAID 5. I have actual backups, plural. I have read that when all HDDs are 14 TB, I can expand the capacity of my RAID 5, which is one of those, I will believe it when I see it.

Solid packaging, device legitimately unused according to SMART/health data. One little red flag here is that US warranty checks with Seagate itself fail (sends you to the retailer), hinting that this might be an import or coming through non-retail channels, which may or may not be an issue for buyers.

I purchased (3) of these for my Synology 923+ and run them in RAID 5. Fully configured, I got 27.9 TB of usable space. I dont have any issues with noise, as others have complained about, but it is a bit noisy when it wakes up from hibernation. I simply cant comment on longevity yet....

Excellent product

This thing is super noisy. It’s easily twice as loud as my 8tb. Also, even though it’s 16tb you only get a little over 14tb, common in the industry but still misleading.

After reading other reviews I confess I was a little concerned, but I purchased two and they both work perfectly on my Synology 920+. The Seagate IronWolf are a bit noisy; I don't know if there are quieter NAS HDDs.

Unfortunately the unit was faulty but the company sorted it out with no hassle.

Unnecessary backstory.. After shelling out £700 to a company to "rescue" the data on a damaged, 5TB external hard-drive. I did a little research and found that hard-drives are less accident-prone when they're "naked" i.e. uncased. However, uncased aka internal hard-drives require 1-5 bay hard-drive enclosures. I bought a Yottamaster enclosure - which found fault with both my 5TB and 16TB hard-drives. The instruction manual was exclusive to Windows OS, and it's website help links were dead! So I returned the Yottamaster forthwith - and bought a Terramaster instead - which is much better. However, that too doesn't recognise the 16TB Seagate hard-drive - it's just too (beaucoup) big. Obviously, the problem isn't with the Seagate 16TB Iron-wolf. Just be aware that most hard-drive enclosures won't 'work with' a 16TB hard-drive - despite their sales promises. But if anyone does have an 'enclosure' that can accommodate a 16TB hard-drive, please do enlighten me!

Frive was dead on arrival, they sent a replacement which does work fine but it's annoying to deal with.
