Strong pick as a cold copy

Recording for this series is mixed CMR/SMR — it varies by exact model number. Verify the exact part number before buying a cold copy: SMR drives throttle writes once their internal cache is full, which is exactly what a full-library backup pass does — a 16 TB cold-copy backup that takes days will slow to crawl on the last terabytes. For the off-site slot of a 3-2-1 plan, prefer the CMR variant of the same capacity; the 3-2-1 guide and the backup tools encyclopedia cover the rest of the chain.

Compatibility verdict

It appears on the official compatibility lists of 89 machines and series — 89 Synology. This is a NAS-class drive: built for 24/7 operation with vibration compensation for multi-bay enclosures — the right tier for most 1-8 bay home or small-office NAS units. Its series rating is on file as SMR (shingled) — the one trait that slows large RAID rebuilds and full-library copies.

Quick answers

Is the WD80EFAX - 68KNBN0 officially compatible with my NAS?

It appears on the official compatibility lists of 89 machines and series — 89 Synology. Every machine page linked below shows the vendor's own list entry, refreshed daily.

Is the WD80EFAX - 68KNBN0 CMR or SMR?

As a Western Digital Red drive, it is rated CMR/SMR varies by model. CMR (conventional magnetic recording) is what a RAID array wants: SMR drives slow rebuilds dramatically. This series mixes both, so verify the exact part number before buying — the <a href="/faq/cmr-vs-smr-nas-drives/">CMR vs SMR guide</a> has a part-number lookup.

Is the WD80EFAX - 68KNBN0 a good NAS drive?

This is a NAS-class drive: built for 24/7 operation with vibration compensation for multi-bay enclosures — the right tier for most 1-8 bay home or small-office NAS units. Its series rating is on file as SMR (shingled) — the one trait that slows large RAID rebuilds and full-library copies.

Can I use the WD80EFAX - 68KNBN0 for a 3-2-1 cold backup copy?

Recording for this series is mixed CMR/SMR — it varies by exact model number. Verify the exact part number before buying a cold copy: SMR drives throttle writes once their internal cache is full, which is exactly what a full-library backup pass does — a 16 TB cold-copy backup that takes days will slow to crawl on the last terabytes. For the off-site slot of a 3-2-1 plan, prefer the CMR variant of the same capacity; the 3-2-1 guide and the backup tools encyclopedia cover the rest of the chain.

What are alternatives to the WD80EFAX - 68KNBN0?

At the same capacity, the most widely listed alternatives are Toshiba MG05ACA800E (393 machines), Seagate ST8000NM0206 (369 machines), Toshiba MN06ACA800 (347 machines). The full ranked list is below.
