Its a good study , but there is not enough data for hgst drives , yet they have very fewer complaints in comparison to WD and Seagate.
Although their total sales is a fraction of wd's and seagates.
Besides their is hardly any noise form hard drives these days , unless they are faulty. the WD red 2tb one was a very reliable and silent drive ,last time when i researched for the same . The WD green , i have heard of the intelli park issue :http://www.instantfundas.com/2011/12/intellipark-makes-western-digital-green.html
which may be can be fixed , that MR boogieman will tell.
I got a seagate 2tb one but still would recommend going hgst or wd , since mine hdd was st2000dm001 which had a good quality batch and a bad quality one. thankfully i got the good one, but still there is too many failure reports for seagate these days.
At the end its all luck though , they are like harry potter wands , they choose the owner , you do not choose them .
