Seagate IronWolf Pro 18TB (ST18000NE000) HDD Review

Simon Crisp December 17, 2020 Featured Tech Reviews, Hard Drives, NAS, Reviews

 

Our review sample IronWolf Pro 18TB was supplied to us without any retail packaging. The IronWolf Pro 18TB is built on a standard 3.5in format but with a thickness of 26.11mm. The drive has a spindle speed of 7,200rpm and there is 256MB of cache.

The drive uses Helium technology which enables Seagate to cram nine 2TB PMR (Perpendicular Magnetic Recording) platters and 18 heads into the drive. Seagate is using TDMR (Two-Dimensional Magnetic Recording) technology in the 18TB IronWolf Pro. TDMR uses two read elements in the drive head to improve tracking accuracy which is needed as tracks are getting ever narrower as the areal density of platters increases.
