I've had one of these for several years now and it's been perfectly reliable. So when i needed another one i was delighted to see the same model was still available. Other reviews commented on the fan volume, but since i already had one i figured these people were just more sensitive to sound than i am. I always have music playing and never notice the fan in the one I already have. So when i got the new one up and running I was surprised to find that, yes, it is noticeably louder than my other one. Using a not entirely accurate decibel program on my phone, it measured to be about 8db louder than the older one. And that appears to be enough difference for me to hear and notice that this thing is always on. I could turn the fan off, but while i can hear it, it doesn't bother me all that much. I wish it had a temperature control though. Since this unit sits idle 90% of the time as it's only used for backups, it's probably not all that hot in there. But still, I recommend this to anyone that wants to build a 2 disk array USB drive and isn't bothered by the hum in the background. Or you can just turn the fan off.One other thing of note, the instructions aren't entirely clear about initially setting up an array. They say when switching raid type, press and hold the reset button. What they don't say is that you have to do this for the initial install as well. I guess you are switching from not set up to set up. LOL  Read Less
