Historical Storage Prices - Raw Data

These are the raw data I collected from some Australian PC magazines from 2002-2007.



There are problems with the data:

- these are not 'best retail price' - just what I could find advertised

- inconsistent markup and discount schedule. Couldn't find a single advertiser.

- not same-same. RAM was DDR 3200, then PC133

- Disks. Ignored cache size, and SATA.

- all drives assumed to be 7200rpm

- didn't collect data on 2.5" drives and SCSI/fast drives.

Summary

The Yr/Yr ratios are used for forward projections.

The 'Est Flash' column uses the current 'best price' (MSY) for flash memory and a Yr/Yr ratio of 3.25.

Flash memory is now very much cheaper than RAM - forward projections not done.
