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.
