Shop owners, landlords, hardware store operators, school administrators and homeowners across Kenya buy this capacity for four to eight camera setups. The problem they keep hitting is simple. A desktop disk pulled from an old computer often fails within months inside a DVR that never switches off. Footage then breaks up, older recordings vanish, and the system lets you down on the night it actually matters. The WD Purple 500GB handles this by giving write operations priority and running ATA streaming, so your recorder keeps writing frames instead of pausing to re-read bad sectors.

Unlike other electronics retailers in Kenya, Mascom International states the model number, workload rating and warranty terms plainly before you pay a shilling. Installers across Nairobi consistently report that WD Purple units survive the heat inside closed DVR cabinets far longer than repurposed laptop or desktop disks. At Mascom International, we're seeing more Kenyan CCTV jobs specify surveillance-class storage from the start instead of replacing burnt-out computer disks six months later. Walk in to Kimathi Street to collect the WD Purple 500GB today, or order it for pay-on-arrival delivery anywhere in Kenya's 47 counties.

Roughly ten to eleven days from four 1080p cameras recording continuously in H.265 at 1 Mbps each. Switch those same four cameras to older H.264 at 4 Mbps and the drive fills in under three days. Set the recorder to motion-triggered capture and retention typically stretches three to four times longer. Two 720p cameras on motion recording can hold close to a month. Your recorder's bitrate and frame rate settings matter more than anything else here.

Yes, and the difference shows up within the first year. A desktop disk is rated for roughly 55TB written per year and short daily use, while the WD Purple 500GB is rated for 180TB per year running 24 hours a day. Desktop disks also pause to re-read damaged sectors, which drops frames from live recordings. AllFrame 4K technology tunes ATA streaming so your recorder keeps writing instead of stopping, which is exactly what you want overnight.

Yes. Any recorder that accepts a standard 3.5-inch SATA disk accepts the WD Purple 500GB, including Hikvision, Dahua, Uniview, CP Plus and Jovision units sold across Kenya. No caddy, adapter or firmware change is needed. It works the same on analogue HD, AHD, TVI and CVI systems as it does on IP camera NVRs, because the recorder handles all the video encoding. Most recorders format the drive automatically on first boot within a few minutes.

Most installations get three to five years of continuous duty, and Western Digital backs the drive with its own 3-year limited warranty period. The rating that matters is 180TB written per year, about 493GB daily, which four to eight cameras stay well under. Rotation at 5400 RPM class speed produces less heat and vibration than 7200 RPM desktop disks, and heat is what usually kills drives inside closed cabinets in Kenya.

For four cameras on motion recording, or two to three cameras recording continuously, 500GB covers a normal one-to-two week review window comfortably. Choose 1TB or larger when you run six or more cameras, need 30 days of footage for insurance or licensing reasons, or record at 4MP and above. At KSh 5,000 the WD Purple 500GB is the sensible entry point for shops, kiosks, small offices and residential gates.

Both are surveillance-class ranges built for always-on recording, and both carry a 180TB per year workload rating. The practical difference is capacity choice: Seagate's SkyHawk line generally starts at 1TB, so there is no direct 500GB rival to compare against on price. If your budget stops at KSh 5,000, the WD Purple 500GB is the surveillance-rated option rather than a gamble on a desktop disk that costs about the same.

The drive operates from 0°C to 65°C on the base casting, which covers hot ceiling cupboards in Nairobi and coastal humidity in Mombasa and Diani. It draws only 3.3W while writing, so a small UPS carries your recorder and drive through short KPLC outages. Sudden power loss is still the main risk to any recording, so we recommend pairing the WD Purple 500GB with a UPS. Dust affects the recorder vents, not the sealed drive.

You need a SATA data cable and a SATA power lead, both normally already inside your DVR or NVR, plus four mounting screws. Hard drives ship bare, so those parts come from the recorder rather than the drive box. Our Nairobi CBD team fits and formats the WD Purple 500GB for walk-in customers, and talks delivery customers through it on WhatsApp at +254 708 852 521.

It costs about the same as a used desktop disk of similar size but is rated for triple the yearly writing and continuous duty. One failed drive means lost footage plus a technician callout, which usually costs more than the price difference. Customers across Nairobi tell us the replacement cycle drops sharply once they move from recycled computer disks to surveillance-rated storage. For a four-camera shop or home setup, that is straightforward value.

Every unit ships with the 6-month Mascom warranty stated above. Buyers across Kenya rely on Mascom International for honest specifications, accurate pricing and CCTV storage that keeps recording long after the installer has left.
