WD Purple Pro WD142PURP 14TB Smart Video Hard Drive

Is the WD Purple Pro WD142PURP 14TB worth buying?

The WD Purple Pro WD142PURP 14TB Smart Video Hard Drive is a surveillance hard drive. It is best for continuous recording in an NVR or surveillance NAS.

At $719.75 on Amazon today, it has a mid-range price: 7 of the 9 surveillance drives we track cost less.

How many days of footage will it hold?

At 14TB, recording around the clock at 15 fps with H.265 and keeping a 25% margin, it holds about 45 days for four 4K cameras, 22 days for eight 4K cameras and 90 days for four 2K cameras.

Motion-only recording stretches each figure about three times further. When the drive fills, the recorder overwrites the oldest footage automatically.

The calculator above works out the figure for your own cameras and settings.

Will it fit my recorder or camera?

It is a standard 3.5-inch drive. Of the recorders and kits we track, 10 accept a 14TB drive, including the eufy HomeBase S380 (HomeBase 3) and Reolink RLN8-410 8-Port PoE NVR. Check your recorder's largest supported drive before you buy.

Why a surveillance drive rather than a desktop drive?

Recorders write video around the clock from several cameras at once. Surveillance drives are built and rated for that constant writing, while desktop drives are built for bursts of use and wear out sooner in a recorder. The price difference is small next to losing the footage you bought the system for.

What should you consider instead?

The WD Purple Pro WD181PURP 18TB Smart Video Hard Drive ($526.49) holds 18TB and costs $193.26 less.

The Seagate SkyHawk AI ST10000VE001 10TB Surveillance Hard Drive ($595.99) holds 10TB and costs $123.76 less.

The Seagate SkyHawk AI ST16000VE002 16TB Surveillance Hard Drive ($741.00) holds 16TB and costs $21.25 more.
