AI Verdict
This 2TB, 7200RPM, 3.5-inch renewed mechanical hard drive is for 24/7 surveillance DVRs that need 60 days of 720p footage storage.
This 2TB renewed drive is a strong fit specifically for surveillance DVRs due to its 24/7 operation design and 7200 RPM speed, which are crucial for continuous video recording. However, its 'renewed' status and older SATA 3.0Gb/s interface make it less ideal for general-purpose or high-performance computing.
If you need guaranteed long-term reliability or a faster interface, look for a brand-new surveillance-grade HDD with SATA 6.0Gb/s and a larger cache.

Pros
- Designed for continuous 24/7 operation in surveillance systems
- Claimed 0 bad sectors, 0 power hours, and 100% health upon renewal
- 7200 RPM rotational speed for faster data access compared to slower drives
- Can store an estimated 60 days of 720P footage at 30FPS
- Advertised for quiet operation and low power consumption
Cons
- SATA 3.0Gb/s interface is an older standard, limiting potential transfer speeds
- 32MB cache is small for a 2TB drive, potentially impacting performance in some scenarios
- Being a renewed product, long-term reliability can be less predictable than new drives
- Some users reported excessive noise from similar renewed drives
- Not optimized for general desktop use, specifically designed for video streaming
Dimension Scores
The 7200 RPM speed is above average for an HDD, but the 32MB cache and SATA 3.0Gb/s interface are limiting factors for peak performance.
Designed for 24/7 surveillance and claiming 0 bad sectors and 100% health as renewed, but the 'renewed' status introduces inherent uncertainty compared to a new drive.
2TB is a common and practical capacity for many home and small business surveillance systems, offering 60 days of 720p footage.
The 3.5-inch form factor and SATA-300 interface are standard for many desktop-based DVRs, but some NVRs might have specific compatibility requirements.
Best For
- Home security DVR systems needing dedicated 24/7 recording storage
- Small business CCTV setups requiring continuous video stream capture
- Upgrading an existing surveillance DVR with a 3.5-inch SATA drive
- Users on a budget needing a specialized drive for video surveillance
Not Recommended For
- High-performance gaming PCs or workstations requiring fast read/write speeds
- Media professionals needing rapid data access for video editing or large file transfers
- General purpose desktop computers or NAS systems
- Users who require the absolute latest SATA interface speeds
Watch Out For
- Some renewed drives, including similar models from this brand, have been reported to produce excessive noise after installation.
- Compatibility issues with specific NVR systems have been noted for similar renewed drives, so verify your system's requirements.
- The 'renewed' status, while claiming 0 bad sectors and 100% health, means it's not a brand-new drive and may have a shorter lifespan than a factory-new unit.
- The SATA 3.0Gb/s interface is older and might bottleneck performance if your DVR or NVR supports faster SATA 6.0Gb/s drives.

What Buyers Say
Many buyers are picking up this renewed 2TB drive for their surveillance systems, often citing its specific optimization for 24/7 video recording. The 4.4/5 rating suggests a generally positive experience, with claims of '0 bad sectors, 0 power hours, 100% health' being a key selling point for a renewed product. However, some users of similar renewed drives have reported issues like excessive noise or specific NVR compatibility problems.
“Needed a cheap drive for my old DVR, this one popped right in and has been recording for weeks, but man, it's louder than my old one was.”
Common Praise
- Easy to install in existing DVR systems
- Functions as expected for continuous surveillance recording
- Provides the advertised 2TB capacity for video storage
- Claimed quiet operation for a mechanical drive
- Good value for a dedicated surveillance drive at its price point
Common Complaints
- Some renewed units can be noticeably noisy, requiring replacement
- Potential compatibility issues with certain NVR models, needing careful verification
- The older SATA 3.0Gb/s interface is not as fast as newer standards
- Being a renewed drive, there's always a slight gamble on its true longevity
Ownership Tips
- The actual noise level can vary significantly between individual renewed units.
- While advertised for 24/7, some users report failure within 1-2 years, which is common for renewed HDDs.
- Performance in a multi-camera setup (e.g., 8+ cameras) might be strained by the 32MB cache.
- The '0 power hours' claim seems to hold up for many upon initial inspection, but actual usage hours quickly accumulate.
Frequently Asked Questions
Is this hard drive new or used?
This is a renewed product, meaning it has been tested and restored to a like-new condition, claiming 0 bad sectors, 0 power-on hours, and 100% health.
Can I use this hard drive in my regular desktop computer?
No, this drive is specifically designed and optimized for 24/7 operation in surveillance CCTV and DVR systems, not for general desktop use.
How much video footage can this 2TB drive store?
It's estimated to record approximately 60 days of 720P footage at 30 frames per second.
Is this drive noisy during operation?
The product is advertised for quiet operation, but some users have reported excessive noise from similar renewed drives.
What does SATA 3.0Gb/s mean?
SATA 3.0Gb/s refers to the interface speed, which is an older standard for hard drives. While sufficient for many DVRs, newer drives often use SATA 6.0Gb/s for faster data transfer.
Buying Guide
When you're looking at a surveillance hard drive like this, you need to understand it's built differently than a regular desktop drive. It's designed to write data constantly, 24/7, which is tough on a drive. 'Renewed' means it's been inspected and repaired, so you're getting a drive that's supposed to be like new, but it's not fresh off the factory line. You're trading a bit of new-product certainty for a lower price.
Capacity (2000 GB)
This is how much video footage you can store. 2TB is enough for about 60 days of 720p video from one camera, but if you have multiple cameras or higher resolution, that time shrinks fast. Think of it like the size of your video library.
RPM (7200)
Revolutions Per Minute tells you how fast the platters spin. Higher RPM (like 7200 here) generally means faster read and write speeds, which is important for consistently writing video streams without dropping frames. It's like the engine speed of your car – faster engine, faster data.
Cache (32MB)
The cache is a small, fast memory buffer on the drive that temporarily stores data. A larger cache helps smooth out data flow, especially when multiple cameras are recording simultaneously. 32MB is on the smaller side for a 2TB drive, so it might struggle a bit with very heavy loads.
Interface (SATA 3.0Gb/s)
This is how the drive connects to your DVR or computer. SATA 3.0Gb/s is an older standard. While it's fine for many surveillance systems, newer drives use SATA 6.0Gb/s, which offers double the theoretical bandwidth. It's like the highway connecting your drive to the system; a wider highway can handle more traffic.
Alternatives
If this drive doesn't quite cut it, look for new surveillance-grade drives with SATA 6.0Gb/s, a larger cache (e.g., 64MB or 128MB), or consider an SSD if your budget and system allow for significantly faster, silent storage with no moving parts.
