How the alternatives compare to the WD 2TB
Seagate Pipeline HD 2TB 3.5-Inch Hard Drive
The Seagate Pipeline HD 2TB shares the 2TB capacity and 64MB cache of the WD drive but targets DVR systems specifically. It features a 3.5-inch form factor similar to the WD AV-GP. The Seagate unit is slightly thicker at 1.03 inches compared to the WD’s 1-inch height. You get a dedicated video streaming optimization for continuous recording. The WD drive uses Intellipower for variable speeds to save energy. If you need strict 24/7 surveillance support with established streaming commands, the Seagate is a solid alternative. The WD remains better for media servers needing lower power draw.
Seagate BarraCuda 1TB 7200 RPM Hard Drive
The Seagate BarraCuda 1TB drops capacity to 1TB but increases rotational speed to 7200 RPM. This makes it faster for desktop PC tasks than the WD 2TB AV-GP, which uses Intellipower. Both drives have 64MB caches and SATA interfaces. The BarraCuda is lighter at 14.7 ounces versus the WD’s 15.9 ounces. It is thicker at 0.79 inches. Choose this if you prioritize speed for gaming or standard computing over video surveillance features. The WD drive is better for storing large amounts of media or running multiple HD video streams without taxing the system with high RPM noise.
Western Digital 500GB WD Purple Hard Drive
The WD Purple 500GB offers significantly less storage than the 2TB WD AV-GP. It keeps the 64MB cache and SATA interface. The form factor is 3.5-inch, matching the original. The Purple drive is optimized for small camera surveillance setups. It is lighter at 15.8 ounces and slightly thicker at 1.03 inches. You save space and cost by accepting lower capacity. Pick this if you only have a few cameras and do not need the 2TB capacity. The original WD drive is better for larger libraries or higher channel counts requiring more sustained storage space.
Western Digital AV-GP 1TB 3.5-Inch Hard Drive
The WD AV-GP 1TB reduces capacity from 2TB to 1TB while maintaining the 64MB cache and SATA interface. It shares the same 3.5-inch form factor and Intellipower technology. The 1TB model is slightly shorter at 4.8 inches compared to the 5.8-inch 2TB version. It is also lighter, though weight data is not fully listed for this specific SKU. This drive is ideal if you need lower power consumption and less storage for surveillance or NAS. The 2TB model provides double the space for photos and videos. Choose the 1TB if space is tight and capacity needs are modest.
Western Digital RE 4TB 7200 RPM Hard Drive
The WD RE 4TB doubles the capacity to 4TB and increases rotational speed to 7200 RPM. It retains the 64MB cache and SATA interface. This enterprise drive is much larger, measuring 9.3 inches in length and 3.7 inches in height. It weighs 1 pound. The WD RE is built for business-critical 24x7 nearline storage. It offers sustained data rates and high duty cycle support. The original 2TB AV-GP is smaller and designed for AV applications. Pick the RE if you need maximum capacity and performance for servers. The AV-GP is better for standard media servers and surveillance with lower power needs.
MDD 6TB 7200RPM Surveillance Drive
The MDD 6TB 7200RPM Surveillance Drive offers triple the capacity of the 2TB WD AV-GP. It matches the 64MB cache and SATA interface. The rotational speed is 7200 RPM, unlike the WD’s Intellipower. The form factor is 3.5-inch, with similar dimensions to the WD drive. It weighs 1 pound. This drive suits users needing large storage for DVR systems. It prioritizes capacity and continuous operation. The WD 2TB is better for lower power consumption and specific AV streaming optimization. Choose the MDD if you need more space for extensive video archives and do not mind higher power usage.
