Thanks for that, James.  I've ordered one as well - "just in case".

Mine has arrived. If anyone is interested, initial findings follow.

The new drive is currently sitting underneath the Raspberry Pi going 
through a read-only badblocks scan. The first 10% of the 1Tbyte drive 
took an hour so I expect the whole scan to take 10 to 15 hours.

The kit came with a clear instruction sheet and was easy to set up. The 
power adapter came with slide-on adapters for UK 3-pin and euro 2-pin 
sockets.

There is a four-way cable which connects USB and power to drive and RPi. 
Maybe these are standard but, if not, it might be hard to replace if it 
got damaged.

The drive has a white LED at the back. As with many LEDs these days it 
is bright enough that I had to turn it away out of sight.

I wasn't sure where a USB drive would appear in the device hierarchy but 
it showed as /dev/sda.

In terms of performance, if my calculations are right the 2.5" drive is 
running at about 27Mbyte/s and it was about the same in write mode. 
While it is scanning the disk the Pi2 CPU is 70% idle and 25% in IO 
wait. The other 5 to 10 percent is mainly taken by usb-storage and 
badblocks.

I've ordered one as well. I'm looking forward to checking usb3 speeds 
with my main desktop.

If I am seeing this correctly, the power arm of the cable is *very* 
short, maybe three inches (8 cm).  That would make it hard to reach the 
power brick.

The power-input arm of the four-way cable is short but it has a female 
connection and the power brick comes with a cable which is about 2.5 
feet (75 cm) long.

I didn't realize the power connector was female.  Thanks.

Still a bit odd, since the power brick has a female connector as well. 
The cable for the brick ends in a micro connector.  Is the female 
connector a micro?  The illustrations don't seem to show it well and 
I've not seen a female microUSB cable end before.  I guess there's 
nothing to prevent that.

IIRC you are in the US and will have a different power brick to me but 
the one I got has as normal USB (rectangular) socket and there is a 
cable which goes from there to a regular micro USB male connector (which 
plugs into the micro USB female connector on the 4-way cable).

In other words, the only unusual element is the 4-way cable. All the 
other parts look to be standard and easily replaceable.

The 4 way cable is what I'm asking about.  The one cable end they don't 
show in any detail is the female USB.  I have to assume it is a female 
*micro* USB connector.  If it is, then great, it all works fine.  I've 
just not seen that particular type of connector before, so I assumed it 
was the larger USB type.  I have since googled and found a number of 
cables with micro female connectors, so I guess that is what it has.  I 
was not able to find a better picture of the 4 way cable when I searched 
on that to verify.  No big deal, I just didn't see how it would work out 
is all.  Now I get it.

I did say that the power lead "plugs into the micro USB female connector 
on the 4-way cable". I added more because I wasn't 100% sure what you 
were asking and tried to cover all the bases.

The gender of USB cables seems to conflict with what we used for 
telecoms equipment. For the latter the gender of the connector depended 
on the innermost element. I cannot take the cable apart here to look at 
it without interrupting the disk test but from pictures online the micro 
USB *female* seems to have an innermost element which looks male, but it 
is recessed, if that makes a difference.

Yes, I said I get it. I was simply explaining why I was confused up to 
that point.  Thanks for the explanation.

In the USB connectors there are no mail or female pins.  The pins slide 
across each other.  So I guess they use the next level up which is the 
housing and does have clear male/female parts... I think.  I just looked 
at male USB micro laying here and I see the "female" connector has a 
tongue that slides into the "male" connector.  I think this is getting 
too far into the anatomy department.  I'll just live with the current 
terminology without questioning it further.

Out of sheer curiosity: does the power inlet end of the 4-way cable look 
easy to mount in the wall of an RPi+disk enclosure? If so, that has to be 
a really nice feature.

Someone else may know what enclosure you are referring to, if you mean a 
specific type, but to give a general answer the power-inlet end is just 
a cable, labelled 5 on the 4-way cable in

  http://cdn.liliputing.com/wp-content/uploads/2015/09/wd-pidrive_02.jpg

You could probably epoxy it to a case, perhaps indirectly.

Were you thinking of a single enclosure for Pi and disk? That would be 
good if the Pi's ports were accessible.

Yes, I see what you mean. Cut neat hole, glue it in., Though it would 
better, and probably equally possible, to make a sort of box out of 0.4mm 
epoxy board that socket 5 is a push-fit in. Gluing a nut to the top of 
the 'box' to take an M3 nylon screw would let you screw it down to anchor 
the socket against the forces needed to push a plug in and remove it.

Yes, exactly so. There probably aren't any custom cases for the RPi and 
disk, but some packaging can be made into a nice enclosure. I have a nice 
octagonal clear plastic box (110mm across, 70mm deep) that used to 
contain Mozartkugeln. This winter I intend to mount my RPi in it with the 
aid of a bit of 0.8mm epoxy board and a few nylon screws. You just need 
to keep eyes open for suitable boxes, or of course you can knock one 
together from epoxyboard and/or Perspex.
