Happy birthday!

The hard disk drive turns 50 today (September 13, 2006):

On Sept. 13, 1956, IBM launched the RAMAC (Random Access Memory for Accounting and Control) 305 and RAMAC 350, two models of a disk drive system that could store a whopping 5MB of data.

From 5 MB then to easily one or two TB in the collection of drives we’ve got sitting around here in various computers, where the largest individual drive contains 250 GB.

Hmm, that means we might be slightly lagging behind Moore’s Law right now, which said:

The complexity for minimum component costs has increased at a rate of roughly a factor of two per year … Certainly over the short term this rate can be expected to continue, if not to increase. Over the longer term, the rate of increase is a bit more uncertain, although there is no reason to believe it will not remain nearly constant for at least 10 years. That means by 1975, the number of components per integrated circuit for minimum cost will be 65,000. I believe that such a large circuit can be built on a single wafer.

Of course he was talking about chips at that point, but if you would apply that law, you’d get: 5 MB * 250 / 2 which equals 5 * 10242 * 225 bytes or roughly 163840 GB. Not quite there yet, are we, not even when considering the 500 GB drives that are for sale these days.

Minor detail here is that Moore didn’t make that statement until 14 years later and I have no idea if hard disk drives developed in line with Moore’s Law up to that point. But I had my little bit of fun anyway. 😉

Irwin fans ‘in revenge attacks’
At the time of writing of that article it’s still speculation only, but an amazing coincidence to say the least. I sincerely hope it’s not true.
