2TB USB 3.0 Drive Uses 2 Watts
« on: March 02, 2015, 06:40:16 pm »

We're doing a little testing with the very small USB drives, connected to an Id.  They're very low power, powered by the USB cable.

Bob and I were trying to calculate what the wattage use was this morning, and we were getting numbers that didn't make sense, so I put a Kill-a-Watt on it tonight.

Including the Id, the whole rig uses about 9 watts.  The highest I saw was 11 watts when I plugged the drive in.

By itself, the Id uses about 6.5 to 7.0 watts, so the drive adds almost nothing -- 2.0 to 2.5 watts.

At 2TB, this drive would store about 5,000 or 6,000 CD's at lossless quality.

I think it's amazing.

The drive is a Seagate SRD00F1.

I've measured a few modern internal drives and most of them used between 2 and 5 watts at idle depending on rotation speed and efficiency, so two watts for an external USB powered drive idling sounds about right.  

Most of the drives I measured used about double their idle when spinning full-speed; what's the seagate like at full spin?

My faves in the current generation of internals are the WD Red's; they use about 2.5 watts at idle and about 4 when spinning.  I haven't bought an external in a few years, so I'll be interested if you all have any recommendations when you're done testing.

Jim,

I'll be re-implementing my MusicPC in a couple of years.  A larger NUC with room for a single 2 1/2" HD (or SSD) seems the right solution for me.  There is a 2 TB Samsung HD that would work for me in that application.

It is only 9.5 mm high and should fit in a NUC or laptop.

So if using an Id and this drive, which sounds pretty neat, could I just dump all my music on the drive, connect it to the Id, connect the Id to my stereo and then control it from JRemote?

Yes.

Sound more and more interesting. Reading the wiki, it has wireless now? How do I give it the wireless password?

There is a utility that allows you to set up a network interface, but it's not for the faint hearted.  I believe it's been discussed before.  Try an advanced search of this board only for "wireless".
