Personal Harddisk History

My first Macintosh (Apple Mac Plus ED) had 2 diskdrives and 2.5 MB internal memory. It was considered a luxury because the Macs in school had only one disk drive and 1 MB internal memory.

After two years I bought a 40 MB removable Harddisk. I figured I would never buy another Harddisk because I could always buy extra cartridges.

Another 2 years later I bought the Iomega Zip drive which offered 100mb per disk cartridge.

The next Harddisk had 500 MB on it and I used it as a portable Mac. It contained my important files and I just hooked it up to the computers I had at home and in the office.

A few months ago I bought a Terrabyte disk. It cost me €1000. I use it at home for backups and DVD storage. I only have 50 Gigabyte left.

In September 1956 IBM launched the 305 RAMAC, the first computer with a hard disk drive (HDD). The HDD weighed over a ton and stored 5MB of data. You can see it in the photo here.

My first mac had a Motorola 68000 CPU running at 8 MHz. My current MacBook pro has a 2.33 GHz Intel Core 2 Duo.

Fortunately the race isn’t over. I just found out that Moore’s Law has been rescuscitated by a new Intel Chip Technology.

How much longer will it be before I own a Petabyte (1000 Terra) Harddisk? According to Moore’s Law it should take only a few years…
