Why 8 TB is a sweet spot
8 TB sits where price per terabyte is keen and the drives are quiet, mainstream and widely stocked. Four 8 TB drives in a four-bay NAS give roughly 21.8 TiB usable in SHR or RAID 5 — enough for a large media library and backups in most homes — at a total drive cost that stays reasonable. It is the capacity we default the calculators to for exactly that reason.
If you expect to outgrow it, note that fewer larger drives (say 16 TB) reach the same capacity in two bays, leaving room to expand and drawing less power. The drive-count calculator shows the trade.
Which 8 TB drive to buy
All the mainstream 8 TB NAS drives are CMR, so the choice is price and noise. IronWolf, Red Plus and N300 trade the top of the CA$/TB table between them; an 8 TB Exos sometimes undercuts them all if you can accept the noise. Buy whichever is cheapest per TB in the table below — they are all safe NAS drives.

Frequently asked questions
What is the best 8 TB NAS drive in Canada?
A CMR standard NAS drive — Seagate IronWolf, WD Red Plus or Toshiba N300 — whichever is cheapest per TB in the live table. All are 24/7-rated and safe for RAID. An 8 TB Exos can be cheaper if noise is not a concern.
How much usable space do four 8 TB drives give?
About 21.8 TiB in SHR or RAID 5 (24 TB in drive-maker terms), surviving one drive failure. In RAID 6 or SHR-2 it is about 14.5 TiB, surviving two. Use the RAID calculator to see other layouts.
Is 8 TB enough for a home NAS?
For most homes, yes — four 8 TB drives give around 21.8 TiB usable, plenty for media and backups. If you have a very large library or plan to grow, larger drives in fewer bays leave more room to expand.
