How Far We Have Come
Rob Pegla from Xiotech Corporation, one of the largest private storage array companies talked about how far we have come in thirty years. In his presentation he used an IBM 5150 as an example; the 5150 is a product released 28 years ago.
Since the IBM 5150 CPU, processing power has improved 1000 times and we now have 1 Million times more memory. Storage capacity has gone from 10MB to over 3 Million times more.
Rob noted in his presentation that during a Windows 7 boot process a system has over 1 Million random writes. Note that these are random writes and not reads. Oh how times have changed.
