Fast and good value for money
Heats up less than the 1st one I bought 2 years ago (48° vs 51° after several hours of transfer, hard drive on usb dock so not ventilated). Recognised by my LDLC and inovu usb docks. Good transfer rate (190Mb/sec on average with peaks at 210Mb/sec, the 1st one I bought had peaks at 195Mb/sec and an average of 180Mb/sec but it wasn't the same source drive, and my configuration isn't new any more, core i7 4790K). Good To/price ratio (I took advantage of a promotion like for the 1st, it's a shame you can't choose in-store delivery any more). Generally quite quiet, but you can hear it scratching at times even if you're not accessing the drive (it's still noisier than the 22TB version that I also own). The ultrastars are very robust, I have 5 of them, one of which is 12TB and has been running 16/24 and 7/7 for 2 years and it's fine (remember to register on the WD site to benefit from the 5 year guarantee). Delivery a little long, ordered on Monday afternoon and received on Saturday morning (but during the promotional period, it's usually quicker).
