Description
The sweet spot: enough storage to forget it’s even there.
The SkyHawk 6 TB is the perfect balance between capacity and budget. With 50% more storage than the 4 TB and a 256 MB cache (4× larger), it absorbs your camera streams with total ease. For a typical 8-channel H.265+ installation, it’s the difference between 20 days and 30 days of history — the psychological threshold most clients and insurers demand.
⚡ 256 MB Cache — 4× More Than the 4 TB
The cache is the buffer between your cameras and the drive. The larger it is, the more simultaneous streams the drive can handle without slowing down. With 256 MB of cache memory, the SkyHawk 6 TB handles the workload of multi-camera installations with total fluidity — even when continuous recording and playback happen at the same time.
Firmware ImagePerfect
The firmware prioritizes continuous video writes and guarantees zero lost frames, even under maximum load with 64 simultaneous HD streams. An office drive handles files — the SkyHawk handles real-time video streams.
1 Million Hours MTBF
A mean time between failures of 1,000,000 hours — over 114 years in theory. The SkyHawk is designed to run 24/7, 365 days a year, with 180 TB/year endurance. That’s professional-grade reliability.
Anti-Vibration Sensors (RV)
Built-in rotational vibration sensors that maintain performance in multi-bay NVRs. Essential when two drives run side by side in the same recorder.
SkyHawk Health Management
SHM continuously monitors drive health and alerts before any failure. Prevention, intervention, recovery — your surveillance system never catches you off guard.

Nexus Carib’s take
« Between the 4 TB and the 6 TB, the choice is simple: 30 days of history is the minimum an insurer or a serious client expects. The 4 TB is enough for a small 4-camera villa. As soon as you move to 8 channels, the 6 TB becomes a must. And with its 256 MB cache, it handles playback at the same time as recording without breaking a sweat. It’s the one we put in 80% of our 8-channel NVRs. »
