Load cycle count with 14TB Seagate Iron Wolf Pro
I put five of the 14TB Iron Wolf Pro drives (ST14000NE0008-2JK101) in my ReadyNAS 628. These drives are in the hardware compatability list. Four of them were installed 24 days ago and the fifth was inserted 20 days ago. SMART data reports Load Cycle Counts of 2894, 2819, 2806, 2801, and 2811.
The only remark in the manual (Iron Wolf Pro NAS SATA Product Manual, Standard 512E* models ST16000NE000 ST14000NE0008 100851637, Rev. F April 2020) is in the Specification summary tables where it says:
Load-unload cycles (command controlled) 600,000
At the rate this is going, I'll hit that 600,000 rating in less than two years!
Any thoughts?

Basic math error in my post. :smileyembarrassed: More like 20 years to hit the 600,000 mark. Still it seems weird to be parking hundreds of times a day for a NAS drive that never spins down.
Used to use Seagate drives everywhere, now using WD.... The manufacturers seem to have good and bad model revisions. At the moment, I see early failure of Seagate enterprise drives in readynas. The WD red drives seem to last forever. The WD gold drives are better - love their reliability, but generate too much heat for the small readynas enclosures.

And, yet, I had WD golds (from the same lot) fail 3 and 5 months after expiration of the warranty. So, they can all run hot and cold. This is one reason I advise people start with the number of drives they really need and add more later rather than filling a NAS for the sake of filling it and having way more space than they need. Doing that spreads out the lots, on time, and cost.
People here seem to have been happy with NAS-purposed drives (both Red and Ironwolf), as well as enterprise-class from both WD and Seagate.
I've stuck with the Reds because most models use lower power than their Seagate counterparts and therefore run at lower temps. But I won't replace my older WD30EFRX with WD30EFAX. I'd either switch to Ironwolf, or replace them with CMR Reds.
