12TB Storage Drives for Home & CCTV | CCTV Master UK
3 products in our Storage range — trade-grade UK stock from CCTV Master.
12TB drives suit CCTV systems recording several cameras continuously, or NAS units needing a large single-volume capacity. This range has three options: a Lenovo ThinkSystem enterprise SATA HDD, a Toshiba N300 NAS drive, and a Western Digital WD120EDAZ.
How to choose
- Use case first. Toshiba N300 is built for NAS environments; Lenovo ThinkSystem targets server/enterprise deployments; WD120EDAZ suits general internal storage.
- Spin speed. Toshiba N300 and Lenovo ThinkSystem run at 7200RPM for faster access; the WD120EDAZ runs at 5400RPM, typically quieter and cooler-running.
- Interface. All three use 3.5" SATA, so check your enclosure or NVR/NAS bay supports this form factor before buying.
- Continuous operation. For CCTV recording, a drive rated for constant read/write cycling (as NAS and enterprise drives typically are) is worth prioritising over a standard desktop drive.
Whichever you pick, confirm your recorder or NAS chassis accepts 12TB drives and 3.5" SATA before ordering — capacity alone won't help if the bay or controller can't recognise the full size.
12TB — frequently asked questions
Which of these 12TB drives is best for CCTV recording?
NAS-rated drives like the Toshiba N300 are designed for continuous read/write cycling, which suits CCTV recording better than a standard desktop drive.
What's the difference between 7200RPM and 5400RPM drives?
7200RPM drives (Lenovo ThinkSystem, Toshiba N300) generally offer faster data access, while 5400RPM drives (WD120EDAZ) tend to run quieter and cooler.
Will a 12TB drive fit any NVR or NAS?
Only if the bay is 3.5" SATA and the recorder or NAS firmware supports 12TB capacity — always check your device's specification first.
Is the Lenovo ThinkSystem drive suitable for home use?
It's built for enterprise/server environments, so while it can work in other setups, a NAS-specific drive like the Toshiba N300 may be a more natural fit for home or small business systems.
