Seagate IronWolf: the standard NAS drive
By Amara Okonkwo · Data checked by Owen Nakamura · Updated · Prices checked Seagate IronWolf is the standard (non-Pro) NAS drive: CMR, rated for 24/7 use and 180 TB/yr, with a 3-year warranty, in capacities up to about 12 TB. For a home or small-office NAS it is one of the safest picks in Canada. Above 12 TB, or for a busy multi-user box, step up to IronWolf Pro. The table below shows current CA$/TB on Amazon.ca.

Where IronWolf fits
IronWolf is Seagate's mainstream NAS line: the direct competitor to WD Red Plus and Toshiba N300. It is CMR, carries a 180 TB/yr workload rating and a 3-year warranty, and includes Seagate's IronWolf Health Management for supported NAS units. Rotational speed is 5400-class on smaller capacities and 7200 on larger ones.
For a family file server, backups and a media library, the standard IronWolf is right-sized: the 180 TB/yr rating is far beyond what a home NAS writes (about 500 GB a day, every day, to reach it). Save the Pro premium unless you genuinely need it.
IronWolf vs IronWolf Pro
The line splits at capacity and workload. Standard IronWolf tops out around 12 TB; above that Seagate sells only IronWolf Pro. The Pro adds a 550 TB/yr rating, 7200 rpm across the range, a 5-year warranty and three years of Rescue data recovery. If your NAS holds up to four bays of home data, standard IronWolf is enough; for a heavily used or business NAS, or any capacity above 12 TB, the Pro is the one on the shelf.
See the head-to-head in IronWolf vs WD Red, which also debunks the stale 300 TB/yr figure often quoted for the Pro.

Frequently asked questions
Is Seagate IronWolf CMR or SMR?
CMR. Every IronWolf and IronWolf Pro drive uses conventional magnetic recording, which is what you want in a RAID array: SMR drives collapse during a rebuild. IronWolf is a safe NAS choice on that count.
What is the difference between IronWolf and IronWolf Pro?
Workload and warranty. Standard IronWolf is 180 TB/yr, 3-year warranty, up to about 12 TB. IronWolf Pro is 550 TB/yr, 7200 rpm, 5-year warranty with Rescue data recovery, and available in the larger capacities. Home NAS: standard. Busy/business or above 12 TB: Pro.
How long does an IronWolf drive last?
Seagate rates IronWolf at 1 million hours MTBF and IronWolf Pro at 2.5 million, with 3- and 5-year warranties respectively. In practice a NAS drive's life is more about workload and cooling than the badge: keep it CMR, keep it cool, and keep a backup.
