[G4] Wear on Extra HD

[Jamie Pruden]

Hi John,

Here are the "raw" numbers for each, but you'll never see this speed  
on any of these interfaces. ;)

I'm converting all of them to megabytes per second...

U160 is rated at 160 MB per second.

66 MB per second

1.5 Gbits per second converts to 187 MB per second. Overhead drops  
this to 150 MB per second, but it's rare to see this speed.

> Firewire 400
400 Mbits per second equals 50 MB per second

> Firewire 800

800 Mbits per second equals 100 MB per second.

Note that many of these are burst rates... that is, the interface can  
flow this, but only for a very short time.

If you look up the following terms on Wikipedia, you'll get more info  
than you'll ever want:

SCSI
Ultra SCSI
FireWire
SATA
ATA66

smiles,
Jamie
