  • 4TB to 14TB Red Pro Model: WD4006FFBX/WD6006FFBX/WD103KFBX/WD122KFBX/WD142KFGX

Purchase links appear where the exact offer is verified. Confirm the named model, quantity and accessories before ordering.

Watch out

  • Confirm the exact model number: several Red Pro capacity points (16TB-26TB) use different prefixes (WD__KFGX vs WD__KFBX) with similar page copy.

Why people pick it

  • True 7200 RPM spin rate with 512 MB cache, the fastest SATA transfer rate in the Red family (up to 285 MB/s)
  • Rated for 550 TB/year workloads, roughly 3x the Red Plus rating, for heavy multi-user NAS use
  • CMR recording, suited to RAID rebuilds and 24x7 operation
  • Approved for NAS systems with up to 24 bays, so it scales beyond home enclosures

Know before you buy

  • Runs warmer and draws more power than 5400 RPM-class drives; check NAS drive-slot cooling
  • Heavier vibration in large arrays; the maker supports up to 24 bays rather than unlimited
  • No maker-linked Amazon listing: the maker sells it direct and through resellers, so buying it takes a search
