Summary: I bought two of these for my video surveillance unit almost a year and a half ago and they are working flawless. The system is on 24/7 recording 4 channels and I haven't had any issues recording or playing back.
Summary: Built to be a little tougher than the Barracuda series with a lower AFR (failure rate) and higher MTBF. Yes there are skeptics. I have one flaky Barracuda in a 2 drive system and decided to replace it with this. So far so good 6 months later.
