The Ratchet and Clank downloadable demo on the PS3 store this week was 1609MB. Not a big deal for todays broadband connections, but think back just a few years ago and it would have been unheard of to attempt to download such a large file from the Internet, plus to think that a ‘demo’ is over 1.5GB. Here’s a few stats to put that in perspective – 1609MB would be:
- 2.3 700MB CDs
- 1117 1.44M floppies
- 2288 720k floppies
- 4576 360k floppies
- 160 times larger than the 10MB hard disk in an IBM PC XT
- 2,860 hours (119 days) of load time from a cassette for a 48k Sinclair ZX Spectrum (assuming 5 minutes per 48k)
In more recent terms though, this is only:
- 0.19 of a 8.5GB dual-layer DVD
- 0.032 of a 50GB dual-layer Blu-ray disk
… kind of puts things in perspective.
