The best 12 TB NAS drive in Canada
By Amara Okonkwo · Data checked by Owen Nakamura · Updated · Prices checked At 12 TB, the value picks are the standard CMR NAS drives and often a 12 TB Exos, which frequently posts the lowest CA$/TB. 12 TB is a strong balance of capacity per bay and price: four in a four-bay NAS give about 32.7 TiB usable in SHR or RAID 5. The table ranks what is in stock by CA$/TB.

Why 12 TB is a good balance
12 TB is where many Canadian buyers land for a four-bay NAS they want to keep for years: four drives give roughly 32.7 TiB usable in SHR or RAID 5, and the price per terabyte is usually close to the 8 TB sweet spot while doubling the runway. It is also the top of the standard IronWolf line: above 12 TB you move to Pro or enterprise drives.
Which 12 TB drive to buy
At 12 TB the field widens: standard IronWolf, WD Red Plus and N300 are all here, and a 12 TB Exos or IronWolf Pro often competes on price too. All are CMR. Buy on CA$/TB from the table below; if the enterprise Exos is cheapest and the NAS lives somewhere you will not hear it, it is a legitimate value pick.

Kept out of the table above: a renewed or used drive has a different warranty and an unknown history, so its price per TB is not comparable with a new drive’s. Each row shows its condition.

Frequently asked questions
What is the best 12 TB NAS drive in Canada?
A CMR NAS drive (IronWolf, WD Red Plus or N300) or a 12 TB Exos if it is cheaper and noise is not a concern. All are 24/7-rated and RAID-safe. The live table ranks what is in stock by CA$/TB.
How much usable space do four 12 TB drives give?
About 32.7 TiB in SHR or RAID 5 (36 TB in drive-maker terms), surviving one failure; about 21.8 TiB in RAID 6 or SHR-2, surviving two. The RAID calculator shows other layouts.
Is 12 TB or 8 TB better value?
They are usually close per TB, so 12 TB gives more runway for a similar CA$/TB: good if you plan to keep the NAS for years. If you need less space now and may add drives later, 8 TB spreads the cost. Check the live tables on both pages.
