Long-retention footage archiving that keeps weeks of camera history intact inside permanently powered DVR and NVR installations countrywide.
Condition: New
Note: price and availability are subject to change without prior notice
WD Purple 14TB WD140PURZ, a 7200 RPM class 3.5-inch SATA drive with 512MB cache and AllFrame AI firmware, is now available at Mascom International for KSh 55,000. This is the largest capacity in the standard WD Purple line, rated for 24/7 recording from up to 64 cameras with 32 concurrent AI streams. The WD Purple 14TB carries a 360TB per year workload rating and 1.5 million hours MTBF. Buy it over the counter at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD, or order it for delivery anywhere in Kenya.
Security installers, shop owners along Luthuli Avenue, hardware dealers, school administrators, and estate managers all hit the same wall. A 2TB drive fills in under two weeks, so last month's footage is already overwritten before anyone needs it. Insurance claims, stock loss investigations, and police reports rarely surface within seven days of the incident. The WD Purple 14TB holds roughly 20 days of continuous footage from sixteen 4MP cameras recording at 4 Mbps, or more than 80 days from eight cameras at 2 Mbps. That retention window is the difference between producing evidence and guessing.
Unlike general electronics sellers who stock desktop drives and label them CCTV storage, Mascom International supplies the drive Western Digital actually built for video recorders. Desktop drives run error recovery routines that pause writes and drop frames during recording. The WD Purple 14TB instead uses ATA streaming commands that keep footage flowing to disk. Installers across Nairobi consistently report fewer corrupted clips and fewer mid-contract drive swaps after switching. At Mascom International, we're witnessing steady demand from integrators standardising on one 14TB drive per site. Walk into our Kimathi Street shop, or order for pay-on-arrival delivery countrywide.
Common Questions About the WD Purple 14TB Surveillance Hard Drive
How many days of CCTV footage can the WD Purple 14TB actually store?
Sixteen 4MP cameras recording continuously at 4 Mbps consume about 691GB per day, giving roughly 20 days of retention on a single 14TB drive. Drop to eight cameras at 2 Mbps and the same drive covers more than 80 days. Motion-triggered recording typically stretches those figures two to three times, since most premises are static overnight. Your exact retention depends on resolution, bitrate, frame rate, and whether your recorder uses H.264 or the more efficient H.265 compression.
Why can't I just use a normal desktop hard drive in my NVR?
Desktop drives are built for short bursts of reading and writing, then idle time. Surveillance recorders write continuously, every second, for years. When a desktop drive hits a bad sector it stops and retries for up to a minute, which shows up as pixelation or missing minutes in your footage. The WD Purple 14TB uses AllFrame AI firmware that keeps writing instead of stalling. Desktop drives also carry a 55TB annual workload rating against this drive's 360TB.
Will the WD Purple 14TB work with my Hikvision, Dahua, or Uniview recorder?
Yes. The WD140PURZ uses a standard SATA 6 Gbps interface and a 3.5-inch form factor accepted by every mainstream DVR and NVR sold in Kenya, including Hikvision, Dahua, Uniview, Provision, and TVT units. Western Digital tests WD Purple drives against a wide list of recorder chipsets and enclosures. Confirm the highest capacity your recorder supports per bay before buying, since some older 2016-era NVR models cap out at 8TB or 10TB per slot.
What does AllFrame AI technology actually do for my footage?
AllFrame AI is the firmware layer that separates the WD Purple 14TB from a general-purpose drive. It uses ATA streaming support to prioritise writing incoming video over pausing to correct errors, which cuts dropped frames and the pixelated blocks that ruin identification. It also routes video, still images, and camera metadata to disk in parallel, so analytics data lands alongside the recording. The result is fewer unreadable clips when you scrub back to a specific timestamp weeks later.
How well does this drive cope with Kenyan heat and power interruptions?
The WD140PURZ operates from 0 to 65 degrees Celsius on the base casting, well above the ambient range in a Nairobi server cupboard or a Mombasa shop ceiling void. Rated MTBF is 1.5 million hours with 300,000 load and unload cycles. Power interruptions remain the real risk to any drive mid-write, so pair the recorder with a UPS. Mascom International stocks UPS units sized for four-bay and eight-bay recorders.
Does the WD Purple 14TB support AI cameras and video analytics?
It does. The drive supports up to 32 concurrent AI streams alongside recording from as many as 64 cameras, which covers face detection, licence plate recognition, line crossing, and people counting on AI-capable recorders. Analytics generate metadata that must be written and indexed while video keeps recording, and that dual load is what the 360TB annual workload rating exists to absorb. Older non-AI drives choke on that combination and start dropping analytics events.
Should I fit one 14TB drive or several smaller drives?
One high-capacity drive keeps power draw, heat, and vibration lower inside the recorder chassis, and leaves bays free for later expansion. The WD140PURZ is rated for enclosures with 16 or more bays, so it works in single-bay and rack-mounted recorders alike. Multiple drives spread risk across units and allow RAID redundancy on recorders that support it. For most Kenyan shop and estate installs of 8 to 32 cameras, one 14TB drive is the cleaner starting point.
How do I install the drive into my recorder?
Power down the recorder and unplug it, open the top cover, then seat the drive in a bay and secure it with four mounting screws. Connect the SATA data cable to the mainboard and the SATA power lead from the supply. Close the unit, power on, then format or initialise the drive through the recorder's storage menu before recording starts. Mascom International's Nairobi CBD counter handles installation for customers who prefer to bring their recorder in.
