The IronWolf is rated as an NAS drive. I used them in an attached external drive in Raid1 for important video content I couldnt afford to lose. I cant speak to longevity but Im confident they will meet and exceed my expectations.

perfect for NAS. I don't really need the AI function in the drives they sit in a UNIFI protect set up. I have the 24TB one in my home protect set up and initially it was loud, but it has become more quite since it finished it originally set up. I have 8 of the 8TB drives with no issues. 2 are cold spares. when they go in I'll order 2 more. I take the drives that are out of warranty and typically put them in our 3rd tier backup NAS systems and they seem to live forever. Technically out of "service life" but that doesn't mean I take them offline, I stick them into a lower use environment to live out their days storing old accounting stuff. Nothing as exciting as VIDEO

Doing LLM training and needed to use a 35TB training file and 3TB validation file. Used 3 of these drives to create a RAID 0 drive with approx 54TB capacity. (this is on Ubuntu and formatted with XFS file system since usual EXT4 tops out at about 16TB file size.) Works great and much faster than a single drive would be due to the striping of RAID 0.

-Transfer rates are good - average a little over 200MB/s, drive to drive on the same LSI HBA on Unraid if it matters. -Temperature is good - average 30C in a 20C room during continuous transfer of files, about the same as a 6TB (WD6003FFBX), and about 5C lower than a 10TB (WD102KFBX). Idle temp is ~26C. This drive and comparables are in the same server/array. - Noise is relatively low, about the same as a 6TB and noticeably more quiet than the 10TB. - Cost per TB is good when on sale, very close to the largest 18-22TB rate.
