- The drive is listed as "Bare Drive" packaging, meaning it does not come with mounting hardware or cables, requiring separate purchases.
- Designed for surveillance, its performance characteristics might not be optimized for general desktop computing tasks requiring faster random access.
- Without specific power consumption figures, its energy efficiency compared to other drives tailored for continuous operation is not clear.
- The listed maximum dimensions suggest a standard size, but confirmation of internal bay clearance would still be required for some enclosures.
