Does this enclosure has power management for the hard disks? Does it idle disks when not in use & spin up on use?

OS X 10.8.5 -> Sleep -> 2xWD7500BPKX RAID1 go to sleep approx in 2-3 minutes.

I'm not sure if it's the enclosure or the OS but on OS X the Put hard disks to sleep when possible option of the System Preferences Energy Saver does put the drives in this enclosure to sleep.

My unit came with a power adapter and works fine with both IDE and SATA devices. I am very pleased with it's performance. Some people leave them connected permanently but I do not do this.

I'm not sure...I don't leave it on when it's not in use. I only turn it on when I go to back up my files and then I power down after I'm done/eject.

The drive spins down according to your computers power settings (as all usbs will) but it never turns off.While spinning its not very noisy (you won't hear it in an office) but its not silent.I'm pretty sure its got wd green cavier as the drive.

I've also had 5 of these running for over nine months with no issues at all. They are in a Synology 1010+ array which means they spin down when not in use. I would expect they have cycled well over 200 times since I installed them.

I have two of these. Yes, they put the drives to sleep after a few minutes of disuse. I believe the amount of time before they sleep is adjustable. The D-Link web site allows you to download the user manual, if you wish to loo it up.

So far, for me, when the computer sleeps, it disconnects the drive. When it wakes, it mounts it again. Sometimes, it just disconnects and reconnects for me while I am working. :(

I only notice when the hard drives spin up, but after that it's not noisy at all. (Small noises tend to bother me). It probably also depends on how loud the hard drive is.

I bought the driveless enclosure version. I then instalked a WD 500 gig laptop drive; so I cannot answer your question. However, my quess who be "yes". Cannot say that 100%.

Like most hard disks these days, the disk in this device enters sleep mode after a few minutes. This causes a slight delay when accessing it after the timeout. The power consumption is interesting - I received one with a 2 amp 12VDC power supply, and the device wouldn't start up. Once I replaced that with a 4 amp power supply, the hard disk spun up and the device started. Even 4 amp at 12VDC is negligible in terms of a home's power consumption, though, and as the disk spins down I should think the average power drain is minute.

I definitely have noticed the fan noise, when I switched to this device from a single-drive enclosure that did not use a fan. But the device was on top of the desk right next to me, and w/o music playing it did create enough noise to make me wish it was quieter. I just moved the unit under the desk, and now it does not bother me at all. As others have said, with 2 drives spinning in there, you don't want to turn off the fan or your disks will be running hot and fail before their time.

Yes. Powering the harddrive may be an issue if the harddrive requires power from a separate power plug (ie. other than the data connector plug).

Yes, behind the red slider. It slowly blinks when the drive is plugged in and idle.

Although I keep the enclosure permanently connected to a computer, that computer isn't powered on 100% of the time. If your question is in regards to the reliability of this enclosure, there shouldn't be any problem with it. It is extremely quiet and never gets even warm to the touch.

The enclosure does have an on/off switch. It worked great for what I needed. Opening and closing the enclosure is a little tricky if you are going to be swapping out drives. Adhesive steps under the top cover make it difficult to remove, but you don't have to use them.

Does the mouse sleep/idle when not in use if the power switch is not turned off?

yes, my goes into a "sleep mode" when not in use after about a minute or so. On the front are a row of blue lights indicating the hard drives are in use. When in the sleep mode they are not lite but when processing they are scanning with blue lights. My 4 hard drives serve as independent and are not tied as one large hard drive. I have three 2 TB and one 3 TB in my case. Works well for me. Never trust any hard drive........I back up with at least two external back ups. I have four external hard drive from WD & Seagate just so I do not loose data. Using the cloud would be out of the question for me.Hope this helps.Bill M. yes, my goes into a "sleep mode" when not in use after about a minute or so.
