Western Digital WD Purple Pro 18TB Surveillance Hard Drive – 7200RPM, 512MB Cache, SATA III, Up to 64 Cameras, 24/7

Missing footage at 3am because your drive dropped a frame mid-recording. That's the problem this kills.

The WD Purple Pro 18TB is built for one job: 24/7 surveillance without gaps. AllFrame technology keeps ATA streaming stable so you don't get pixelation or dropped frames when 64 cameras are writing at once. 7200RPM, 512MB cache, SATA III at 272MB/s — it's tuned for write-heavy, low-bit-rate video workloads, not random desktop tasks.

550TBW workload rating. 2.5 million hour MTBF. Five-year warranty. TLER and ATA streaming support included. Drop it into your NVR or DVR and stop worrying about the drive being the weak link in your security chain
