I bought this drive to use in a NAS installation. I realize its marketed as a surveillance drive but that also means its expected to have a 100% duty cycle, this drive is meant to be written to pretty much continuously. It should work fine in a nas installation.

Very fast and realiable hard drive. Not that loud .worth the extra money in buying this. Remote playback is faster compared to my old 2TB drive which was slow in play back. Build quality is good. No problems found so far with this item fir use in a security Hikvision dvr

kinda worried as its extremely hot in the synology NAS. wish it could last more than 3 years.

Excellent. No hassles at all
