Best 8TB NAS hard drives
8TB is the value sweet spot for a home NAS: enough room to grow without the per-terabyte premium the biggest drives charge. Every pick below is a CMR drive rated for NAS or enterprise duty (never SMR), ranked by measured failure rate.

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.
