Seagate IronWolf Pro ST6000NE000 review

The ST6000NE000 is a 6TB IronWolf Pro drive with 256 MB of cache and a 7,200 rpm spindle. Seagate rates it for up to 24 bays. That figure points at larger NAS enclosures and multi-drive arrays rather than a single-bay or two-bay box.

The drive is built around endurance and cover. Speed and quietness come second, and the specifications show where the trade-offs sit.

Seagate rates the drive at 300 TB/year and 1,200,000 hours MTBF. The 300 TB/year workload rating is the figure to check against the writes your array will see, such as backups, media libraries and shared project storage.

The bay rating matters as much as the workload figure. Seagate rates the drive for up to 24 bays. If you plan to fill a large enclosure over time, that rating suits the job.

The MTBF is a rating, not a promise about any single drive. Plan for failure anyway: use redundancy and keep separate backups.

The datasheet lists the recording method as perpendicular. It does not name CMR or SMR for this model. If rebuild behaviour in RAID matters to you, check the exact model number against the manufacturer's current documentation before you buy.

The warranty is 5 years limited, and it suits a drive you expect to keep in service for years.

The drive also includes a 2-year Rescue Data Recovery plan. You must activate it by registering the drive, and availability varies by country. If you want the plan, register the drive as soon as you install it, and confirm it applies in the UK. The 5-year warranty and the 2-year recovery plan run for different lengths, so note both dates when you register.

Seagate lists a maximum sustained transfer rate of 214 MB/s for the 6TB model. That figure is a maximum rather than a guaranteed floor. The rate is given for the 6TB model specifically, and the drive lists 256 MB of cache and a 7,200 rpm spindle alongside it.

This is the drive's weak point. The datasheet lists noise of 2.7 bels at idle and 2.7 bels during seek. The drive spins at 7,200 rpm. The datasheet gives the same figure for idle and seek.

That suits a NAS in a garage, cupboard, server room or rack. It suits a desk or living room less well. Seagate's figures here do not give a power draw, so size your power and cooling for a 7,200 rpm drive across every bay you plan to fill.

This drive suits buyers who put cover and rated workload first. The 5-year warranty and the data recovery plan matter most when the array holds data you cannot easily replace. The 300 TB/year rating and the 24-bay rating suit multi-drive builds.

It suits buyers less well when noise matters, or when they need confirmation that the drive uses CMR. Those points are worth settling before you order several.

The listed figures are 6TB capacity, 256 MB cache, 7,200 rpm, perpendicular recording, 300 TB/year workload, 1,200,000 hours MTBF, up to 24 bays and a 5-year limited warranty. Taken together, they favour cover and workload rating over quiet running, and they leave the CMR question to be checked before purchase.
