WD Purple AV 1TB, 64MB Cache, 5400rpm, SATA 6Gb/s - WD11PURZ

WD Purple AV 1TB (WD11PURZ) is a 3.5" internal hard drive designed specifically for video surveillance systems. With a capacity of 1TB, a rotation speed of 5400 rpm, and 64 MB cache, this is a solid solution for DVR/NVR recordings where reliability and continuous recording are more important than peak speed. The Purple series is aimed at 24/7 operation in surveillance, and here you also get a serious resource with 1,000,000 hours MTBF. It comes with a 36 months warranty, which further secures your investment.

What you get

With 1TB space, you can store a long archive of recordings from several cameras without immediately thinking about expansion. The speed of 5400 rpm is typical for surveillance drives – lower temperature, less vibration, and higher reliability during continuous recording compared to “desktop” drives that are not made for 24/7 load. 64 MB cache helps with buffering constant data streams from several cameras simultaneously, making the recording smooth and without dropped seconds. The 3.5" form factor and internal placement make it easy to integrate into standard computer cases, DVRs, and NVR recorders. The weight of 0.45 kg is completely normal for this class and facilitates installation in more compact chassis.

• 1TB capacity – enough space for long-term recording from several cameras in a typical video surveillance system.
• 5400 rpm – optimized speed for lower noise and less heating during 24/7 operation, which is important for reliability.
• 64 MB cache – smoother continuous recording of video streams and better handling of multiple parallel recordings.
• MTBF 1,000,000 hours – a serious indicator of reliability during prolonged, continuous operation in security systems.
• 3.5" form factor – standard size for desktop machines, DVR/NVR devices, and surveillance recorders.
• Internal drive – mounts directly in your system without the need for external enclosures or additional accessories.
• 36 months warranty – three years of peace of mind for your main recording medium from video surveillance.

Who it is suitable for

This WD Purple AV 1TB is suitable if you are building or expanding a budget or small video surveillance system – home, for a small office, shop, or garage. It also makes sense as an additional recording drive in an existing DVR or NVR, where 1TB is sufficient and you are not aiming for huge archives. It is not the best choice if you are looking for maximum performance for desktop, gaming, or heavy applications – it is focused on stable video recording, not speed.

The combination of 1TB capacity, 5400 rpm, 64 MB cache, and 1,000,000 hours MTBF makes this drive a very sensible choice for reliable, continuous video surveillance on a reasonable budget. If your goal is to record long and without drama, the WD Purple AV 1TB fits perfectly into your system.
