[Scottish] Drive performance...

[Kyle Gordon]

Cure my curiosity folks... before I open up the machine and put the kit in for 
some bonnie++ tests...

What is likely to be faster... both hosted in a Dell 1600SC and set up in a 
software (mdadm) RAID5 setup. Total space is not an issue.

3 18.2GB Quantum Atlas 3 drives, connected to an Adaptec 29160 - giving 36GB

or

Caviar 80GB (Master) + DiamondMax 60 (slave) on the internal IDE controller + 
Deskstar 120GXP on a PCI Ultra100 TX2 card - giving 120GB

Am I wrong in thinking that the SCSI drives will be faster than the IDE setup, 
given their age? The DiamondMax is ATA66 whereas the Caviar and DeskStar are 
ATA100, but the Quantums are Ultra160. The Quantums however, are older, and 
the primary use of this will be ~, where random access will be preferred over 
sequential streaming.

Any thoughts, or am I being delusional given the time of day, and should just 
be sensible and stick the SCSI drives in?

Cheers,

Kyle
