Why 8TB for a NAS

8TB usually wins the price-per-terabyte math for a home or small-office build. The biggest drives charge an early-adopter tax; 8TB sits well under it and still gets a 4-bay RAID 5 array to roughly 24TB usable - enough for most media libraries, backups and photo archives, with bays left to grow into.

What to look for

Stick to CMR, NAS-rated drives with a 24/7 duty cycle and proper RAID error recovery. Where Backblaze has failure data the table ranks by it; most consumer 8TB NAS models have none, which is normal - judge those on warranty and workload rating instead. One catch worth repeating at this capacity: some 8TB consumer drives are quietly SMR, so confirm the recording tech before you buy.

Frequently asked questions

Is 8TB enough for a NAS?
For most homes, yes. Four 8TB drives in RAID 5 give about 24TB usable - plenty for media, backups and photos. Buy larger only if you expect your library to outgrow it, since adding capacity later usually means replacing drives.
Are all 8TB drives CMR?
No - some 8TB consumer drives are SMR, which is risky in a RAID array. Every drive on this list is CMR; check any model on our CMR/SMR reference if unsure.
