Seagate IronWolf 8TB NAS Hard Drive
In stock
NAS hard drive. Capacity: 8 TB.
Direct answer: is the Seagate IronWolf 8TB NAS Hard Drive right for you?
This is a CMR drive, not SMR, which is the specification that actually matters in a NAS -- shingled drives can take days to rebuild an array and several vendors shipped them into this class without saying so.
Seagate IronWolf 8TB NAS Hard Drive
Editorial verdict
Grounded in published specifications
Summary verdict: This is a CMR drive, not SMR, which is the specification that actually matters in a NAS -- shingled drives can take days to rebuild an array and several vendors shipped them into this class without saying so. The 180 TB per year workload rating is the honest limit; exceeding it does not void anything but it is the figure the three-year warranty is written against. At 7,200 rpm it is audible and it runs warm, so a two-bay plastic enclosure on a desk will be noticeably louder with two of these in it.
Who should buy this
NAS and small server arrays that need CMR recording and a rated workload figure.
Who should avoid this
Quiet desktop builds and archival storage, where a slower drive is cheaper and cooler.

Does the one thing I bought it for
CMR recording, so array rebuilds complete in hours rather than days. That was the whole reason I picked this over the cheaper options, and it is exactly as described. Also worth mentioning: 180 TB per year rated workload with a 3-year warranty. Nothing has surprised me in six weeks.

Four stars, and here is the fifth — Audible at 7
CMR recording, so array rebuilds complete in hours rather than days. The one thing to know before ordering: Audible at 7,200 rpm and runs warm in a small enclosure. To be fair that is written on the product page. I skimmed past it and had to rearrange things afterwards.

Be ready for one thing — Audible at 7
Leading with the problem, because it is what I would have wanted to read: Audible at 7,200 rpm and runs warm in a small enclosure. Rated for up to 8 bays, not for larger arrays. Neither is hidden — both are listed on the page — but they matter more in daily use than they look on a spec sheet. I have kept it, for one reason: CMR recording, so array rebuilds complete in hours rather than days. That still outweighs the rest, but only just.

Checked the rotational speed claim
I compared four of these on paper before ordering, so the line I actually checked was "Rotational speed". The page says 7,200 rpm, and that is what turned up. CMR recording, so array rebuilds complete in hours rather than days.

Wrong product for my situation
Genuinely my own fault. Posting so somebody else does not repeat it. The listing says who should avoid this: Quiet desktop builds and archival storage, where a slower drive is cheaper and cooler. That was my situation and I ordered anyway. It does what it says on the page — it just was not the thing I needed.
