(1) Bad job, Mr Western Digital. How many years has it taken you to finally, finally get a clue and start making proper hybrid drives? Seagate got the idea right ... how long ago was it now? Two years? Three years? More? So long ago now that I can't even remember my first one or how many times I've replaced it with bigger ones as the new models arrive. Way too long whichever way you slice it.
(2) Good job, Mr Western Digital. Congratulations on not just catching up but making the extra effort to lift the performance bar.
(3) Good job Mr Seagate. Your hybrid drives have provided sterling service and are, in particular, a great way of rejuvenating tired laptops without sacrificing capacity.
(4) Bad job, Mr Seagate. Your biggest current hybrid model has been around since Adam was fingering the three little hairs on his chin and wondering when someone would invent supermarkets so he could buy his first razor. Where are the new models with more space (essential!) and more speed (desirable)?
(5) If I read things properly, the WD product won't be compatible with most existing hardware, so is of little immediate interest. But with decent luck, it will put the frighteners on Mr Seagate and encourage him to get off his arse and put some nice new product out. Good!
