I’ve been allowing my Drobo FS to run pretty much 24/7, and I’ve noticed that the fan never stops blowing, even though the hdds are set to spin down after 15 minutes of inactivity; also, the power brick tends to get pretty hot. Are these things normal? Should I be shutting my FS down at night?
I was just about to ask the same question. Would it be better for the Drobo to be kept on 24/7 on shutdown when your not using it and turned back on again when you want to?
A NAS is usually not supposed to be turned off, I don’t even put it on spin down, this will preserve disks, all that stopping and starting to spin is not good, unless you want to preserve electricity
Thanks for the info! Guess I am keeping my baby on 24/7, and if anything were to happen to it…well that’s where drobo care comes in
24/7 for me as well. Too bad the fan doesn´t stop and too bad it isn´t a silent fan in the first place. Im considering to replace the fan to make it dead silent.
It of course depends on your usage, if you only connect to it 1 time a week, put it in spindown, if you use it like me, running music every day, watching movies, connecting from work etc etc, keep it on 24/7
24/7 for me as well. I have spin down set at an hour so its quiet over night and when I’m not using it for a long time.
graviton’s point about spin down is valid that you don’t want drives spinning up/down constantly, but i’m on the side that also feels its bad to have your drives spinning constantly when you aren’t using them for hours/days. Of course, none of this would matter if the Drobo support SSD drives!
For anyone interested, http://hintsforums.macworld.com/archive/index.php/t-57656.html has some points about the spin down topic and a few other links to read.
For those interested in power consumption, I recorded some instantaneous power usage stats for my Drobo FS.
powered off: 1.9-2.1 Watts
on with no disks: 11-11.3 Watts
3 disks spun down: 15-16 Watts
3 disks spinning: 36-37 Watts
3 disks active: 40-41 Watts
Based on this, my Drobo FS with 3 drives spinning 24/7 consumes roughly 315 kWh/yr compared to roughly 88 kWh/yr if it was not spinning at all. Obviously real usage would be somewhere in the middle.
I also found that the specs for my drives report 300,000 start/stop cycles which is roughly 164 cycles per day over a 5 year period.
