Hard drive HP 7945A went on sale in 1985 and at that time it was just a device still an accomplishment. With capacity of 50 MB, it cost $ 7,500, and at such considerable size that's considered very portable.
And now, these discs still sold on Ebay, where there are 100-150 dollars, and by the way, many of them still work fine. However, what is nowadays 50 MB of memory? ))
