WD Purple 1TB Surveillance Hard Drive (model WD11PURZ) is now in stock at Mascom International for KSh 8,000, built around a SATA 6Gb/s interface, 64MB cache, and continuous 24/7 video duty. You can buy the WD Purple 1TB Surveillance Hard Drive over the counter at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD. Every unit is brand new and sealed in factory anti-static packaging. The WD Purple 1TB Surveillance Hard Drive transfers at up to 110MB/s and carries a 180TB-per-year workload rating. That figure is roughly three times what a desktop disk is rated to handle.
Security installers, shop owners, landlords, school administrators, and hotel managers across Kenya keep meeting the same failure. A desktop disk drops into a DVR, runs for eight months, then dies mid-week and takes the footage with it. Desktop disks park their heads during idle spells and were never rated for nonstop writing. The WD Purple 1TB Surveillance Hard Drive sits in a different class. It writes video continuously, tolerates the heat inside a sealed recorder cabinet, and keeps frames intact when several cameras stream at once. Mascom International supplies it to installers working across Nairobi, Mombasa, Nakuru, and Kisumu.
Unlike other electronics retailers in Kenya, Mascom International stocks the WD Purple 1TB Surveillance Hard Drive as genuine Western Digital product with the full three-year manufacturer warranty intact. At Mascom International, we're seeing installers replace failed desktop disks in two-year-old CCTV setups every single week. Customers across Nairobi report that a purpose-built surveillance disk removes the recurring cost of annual replacements. Walk into our Kimathi Street shop to check the label and serial number before paying. Or call +254 708 852 521 and take pay-on-arrival delivery anywhere across Kenya's 47 counties.
Common Questions About the WD Purple 1TB Surveillance Hard Drive
What makes the WD Purple 1TB different from a normal desktop hard drive?
The WD Purple 1TB is rated for 180TB of data written per year, roughly three times a desktop disk's rating. Desktop drives are built to run in short bursts, then idle. A DVR never idles. It writes video every second of every day. The WD Purple 1TB also runs AllFrame technology, which tells the drive to keep writing video rather than pause for error retries. That single behaviour difference is why footage gaps appear on desktop disks.
How many days of CCTV footage will 1TB actually hold?
Expect roughly 21 days from four 1080p cameras recording continuously in H.265. The 1TB drive formats to about 931GB of usable space. A single 1080p camera writes near 11GB per day at moderate bitrate, so one camera stretches to about 85 days. Eight cameras drop you to around 11 days. Switching from continuous capture to motion-triggered capture typically doubles or triples each of those figures. Most Nairobi shop owners settle on motion capture for exactly that reason.
How many cameras can the WD Purple 1TB handle?
Up to 64 single-stream HD cameras, according to Western Digital's own specification. In practice your DVR channel count is the real limit, not the drive. A 4-channel or 8-channel recorder is the common setup in Kenyan shops, homes, and small offices. The 64MB cache and 110MB/s sustained transfer rate leave plenty of headroom at those channel counts. Larger installations should still step up to the 4TB or 6TB tiers for useful retention.
Does the WD Purple 1TB work with Hikvision and Dahua recorders sold in Kenya?
Yes. Western Digital validates WD Purple drives against a wide range of DVR and NVR enclosures and chipsets, including the Hikvision and Dahua units that dominate Kenya's security market. The drive uses a standard SATA 6Gb/s connector and a standard 3.5-inch chassis. Your recorder formats it during first-time setup. No separate driver, adapter, or software is needed. Mascom International can confirm fit against your specific recorder model before you buy.
Is the WD Purple 1TB worth KSh 8,000 for a small shop or home?
For a four-camera setup, yes. Spread across the three-year warranty period, KSh 8,000 works out near KSh 7 per day. A failed desktop disk costs you the replacement price plus the footage from whatever incident made you check. Shop owners along Kimathi Street and Moi Avenue lose more than that in one unrecorded theft. If you need longer retention, ask our team about the 2TB and 4TB options.
How long does the WD Purple 1TB last running 24 hours a day?
Western Digital rates it at up to 1 million hours MTBF under continuous testing conditions, backed by a three-year limited warranty. Real service life depends heavily on heat and power quality. Recorders mounted in unventilated ceiling boxes or locked cabinets run hot and fail sooner. Installers who mount recorders with airflow around them regularly report five years or more from a single drive. Keep the cabinet dust-free.
What happens to my footage during Kenya Power outages?
Sudden power cuts are the biggest threat to any recording drive, including this one. The disk can lose the file it was writing at the moment power drops, and repeated hard shutdowns shorten drive life. Pair your DVR with a small UPS rated for 15 to 30 minutes of runtime. That gives the recorder time to close files properly. Mascom International stocks UPS units suited to CCTV setups.
Can I install the WD Purple 1TB myself, or do I need a technician?
Most people manage it in under fifteen minutes. Power off the DVR, unplug it, open the top cover, seat the drive in the bay, and connect the SATA data and power leads. Screw it down, close the case, power up, then format the drive through the recorder menu. Your recorder's manual shows the exact sequence. If you prefer, our Kimathi Street team talks you through it over WhatsApp.
How does the WD Purple 1TB compare with the Seagate SkyHawk 1TB?
Both target the same job and carry the same three-year warranty and 180TB annual workload rating. WD Purple runs AllFrame technology; SkyHawk runs ImagePerfect firmware. Both cut frame loss the same way. Cache sizes and sustained speeds sit close enough that neither wins on paper. Choose on price, stock availability, and whether your recorder brand publishes a compatibility list naming one. Mascom International stocks both and quotes honestly on either.
Technical Specifications
Storage Capacity and Retention Math
- 1TB raw capacity formats to roughly 931GB usable, which is what your DVR menu will display.
- One 1080p camera capturing continuously in H.265 consumes near 11GB daily, giving about 85 days of footage.
- Four 1080p cameras running nonstop fill the disk in roughly 21 days before the oldest footage overwrites.
- Eight cameras at the same settings leave you close to 11 days of stored video.
- Motion-triggered capture instead of continuous capture typically stretches all those figures two to three times further.
- Dropping the frame rate from 30fps to 15fps cuts file sizes almost in half with acceptable clarity.
Interface Speed and Cache Behaviour
- SATA 6Gb/s connector plugs into every DVR, NVR, and desktop motherboard sold in Kenya today.
- Sustained transfer reaches up to 110MB/s, leaving headroom for the full 64-camera single-stream ceiling.
- A 64MB cache buffers incoming video so short processor delays never translate into dropped frames.
- 5400 RPM class spindle speed keeps heat and power draw lower than 7200 RPM desktop disks.
- CMR recording, not SMR, means overwrite cycles stay predictable when the disk loops old footage.
- Backward compatible with SATA II ports on older recorders, running at the lower negotiated speed.
AllFrame Technology and Video Stream Handling
- AllFrame technology adjusts ATA streaming commands so the drive favours writing video over retrying error correction.
- Reduced frame loss matters when a suspect crosses frame during the second a desktop disk stalls.
- Handles write-intensive, low bit-rate, high stream-count workloads typical of mainstream security installations across Kenya.
- Multiple streams per camera are supported, so main-stream plus sub-stream setups record without conflict.
- Playback stays smooth during scrubbing because the firmware separates read requests from ongoing write duty.
- Standard desktop firmware lacks these streaming commands, which is why gaps appear on repurposed PC disks.
Recorder and Camera Compatibility
- Supports up to 64 single-stream HD cameras, covering nearly every DVR and NVR channel count.
- Validated against a wide range of DVR and NVR enclosures and chipsets from major security brands.
- Works in Hikvision, Dahua, and similar recorders widely installed across Nairobi, Mombasa, Kisumu, and Eldoret.
- Rated for storage enclosures using up to eight drive bays at this 1TB capacity tier.
- Also functions as a standard internal disk inside desktop towers running video management software.
- No proprietary formatting is required; the recorder initialises the drive during its own setup routine.
Reliability Ratings and Continuous Duty
- Workload rating of 180TB per year, roughly triple the annual figure quoted for desktop drives.
- MTBF rated up to 1 million hours under the manufacturer's continuous operation testing conditions.
- Built to tolerate the heat swings and vibration found inside sealed recorder cabinets and enclosures.
- Made for 24/7 always-on duty rather than the short intervals a desktop disk expects.
- Three-year limited warranty from Western Digital reflects the intended service life under nonstop use.
- Tarnish-resistant components apply only to 3TB and larger models, so this capacity tier excludes them.
Physical Build and Installation Requirements
- Standard 3.5-inch form factor fits the drive bays in every full-size DVR and NVR.
- Mounts with four standard screws; most recorders ship with the screws and SATA cable included.
- Requires one SATA data connector and one SATA power lead from the recorder's internal supply.
- Bare drive construction with no external casing, since it lives permanently inside the recorder chassis.
- Draws no external power adapter, taking everything it needs through the internal SATA power connector.
- Ventilation matters in Kenya's warmer coastal towns, so leave the recorder cabinet unblocked and dust-free.
Package Contents
