Heavy isn’t always a bad thing. Could be better constructed or larger battery. Not everything needs to weigh as much as a tiny phone. A .2 lb difference isn’t really something to whine about in a headline like it’s 100x the weight. Will help build muscle.
As someone who has worked in the it industry doing server work for 20+ years, definitely cannot agree with used drives. Always buy new if you can. Refurb drives are a huge risk whether or not they could have subsequent issues after being repaired. If you value your data, do not buy refurbs.
Edit - also consider most refurb drives are prob only a year warranty vs a probable 5 year on new WDs. To save a couple bucks, totally worth the extra warranty period.
You think a mechanical hdd is sufficient for playing a 100gb game? That would be so painful it’s not even funny.
