HDD choose

HDD performance is crucial for your recording device operation.

1. Strongly recommend that you purchase Enterprise HDD for any of

your rackmount server NVR etc.

For example Seagate Enterprise HDD or WD Gold HDD is the good

choice for your non-stop video recording.

HDD quality is not only important in your video recording, only critical

while your using RAID-5/RAID-6 rebuilding your video data.

WD Surveillance HDD or Seagate Surveillance HDD usually are good

for small DVR/NVR system recording, not designed for rackmount

multiple HDDs recording. The major difference between “Surveillance

HDD” and “Enterprise HDD” is the HDD capability on the HDD vibration

durability. More HDDs on the same NVR will generate more vibration

exponentially, at end will dramatically shorten your HDDs lifecycle. Not

to mention that typical WD Purple HDD series have a workload rating of

around 360 TB/year, which won’t be enough for today NVR Server

video recording and operation.

The typical Lifecyle for Surveillance type HDDs for the Rackmount NVR

will be less than 1 year, bad choice.

2. The other key factor to ensure your NVR recording success is to

choose your HDD from your RAID card vender recommend list. For
