I want to upgrade what previously was the fastest ATA IDE or PATA laptop hard drive in my PPC G4 Mac Mini 1.5ghz and my Powerbook 1.5ghz 12" -- both have the 100gb Hitachi Travelstar 7200rpm drives.
The 250GB Western Digital Scorpio 2.5" Laptop Hard Drive PATA IDE version has a seek time of 100 ms which is the same as the Travelstars, even though the Scorpio drives are 5400rpms vs the Hitachis' 7200rpms.
I think the much larger drives have bigger platters or something, which compensate for faster seek speeds, despite the slower rpms? Someone on MR once explained this.
Anyway, the 160gb 5400rpm laptop hard drives have a 11ms seek time, so they seem slower than the 250gbs.
I just want to maintain speed but bump storage with the new drive, especially in the Mac Mini. If not, I'm going to firewire a huge desktop drive and start using that as my start up drive on the mini.
Want to max out the PPC Mini experience. Any thoughts?
