Product Description
The Seagate ST6000NM0275 is a 6TB enterprise-class hard drive built for CCTV systems that record around the clock, not just office storage.
Why this matters for a CCTV setup
6TB gives you a solid block of recording capacity for an NVR or DVR running several IP or analogue cameras continuously. The 3.5-inch SATA 6Gb/s interface is the standard fitting used in almost all consumer and prosumer recorders, so it's a straightforward slot-in replacement or capacity upgrade if your recorder takes 3.5" drives.
Running at 7200RPM, it's quicker than the 5400RPM drives found in budget "surveillance" models, which helps when several camera streams are writing to the disk at once, or when you're also pulling footage back for review. Seagate rates it for 24/7 operation, which matters — a drive built for daytime desktop use will wear out fast if left recording continuously.
It also includes Self-Encrypting Drive (SED) hardware encryption, meaning the data is encrypted at the disk level automatically — useful where footage needs to meet data protection or compliance requirements. Advanced Format (AF) 4K sectors improve storage efficiency and are supported by current NVR/DVR firmware and operating systems.
Where it fits
Designed for NVRs, DVRs, servers and storage arrays, including RAID setups where sustained write reliability matters more than peak speed.

Frequently Asked Questions
Will this drive work in my NVR or DVR?
It uses a standard 3.5-inch SATA 6Gb/s interface, so it's compatible with NVR, DVR, server and storage array bays that take a 3.5" SATA drive.
Is it suitable for continuous recording?
Yes — it's designed for 24/7 enterprise and data centre use, which is a step up from desktop drives not rated for constant operation.
What does SED mean and why would I need it?
SED stands for Self-Encrypting Drive — it encrypts data at the hardware level automatically, which helps if your footage needs to meet data protection or compliance requirements.
Is 7200RPM better than the 5400RPM drives sold for surveillance?
7200RPM gives faster, more consistent performance, which helps when multiple camera streams are writing to the disk at the same time.
