They are? You're telling me that HDD storage is cheaper per GB than an SSD? Wow. You learn something new every day, and there was me thinking your well formed argument was originally "If you need more space than 512Gb for everyday use your doing something wrong". Price per GB never came into it, but I guess that's was just me being thick. But back on track... I do access more than 512GB of data every day, so by applying your logic I've clearly got very little intelligence. Really? Damn. I'm really quite surprised at this breaking news. I'm welling up in fact. This shocking news is actually very distressing as I've always relied on my brain up until now. At least knowing this does explain my lifelong inability to solve the Seven Bridges of Königsberg problem. I will be sure to let everyone I meet that my 'Corky42 certified Brain' score is significantly more petite than I would otherwise have believed. But you've made the connection between the data I access daily and my intelligence and surely you must be speaking the truth otherwise you wouldn't have said it. Thanks for letting me know. This is life altering stuff. I will be sure to read all your future posts as if my very life depends on them. For maybe it will in some small way, as I now believe that you have many great lessons in life you could teach me. By hanging onto your every word I will endeavour to become a better and 'more brainy' person. Just like you. Would you be so generous as help me now? Seeing as you seem to know more about my daily usage patterns than I do (After all I'm such a thicky), would you be so kind as to enlighten me exactly which of my data I should not be using? I'll do my best to follow your line of thought this time, but please don't use any complicated words. You must remember I'm a girl of very little brain.
