Well as you might know about me on MR, i love my new ibooks and old Tibooks. (Also love old iMac g3s, but currently don't have any at my own house.) I have had a bad relationship with Fujistu OEM apple laptop harddrives. The original one on my first TIbook failed and was then replaced in Spring of last year, only used for 4 months and replaced and now I take it out to use it and it fails. So I have been really weirded out as to whether or not I get an Hitachi or Fujistu OEM drive in my new iBooks. Also Apple just replaced the hd in my 1ghz Titanium pb -- and it is the same crappy OEM Fujistu 4200 RPM 60 gig drive that is my current 1.33ghz ibook. AND BOTH Fujistus only have a 2mb cache. While the OEM Hitachi 60gig 4200 rpm drives have an 8mb cache. I had an Hitachi in my 1.2ghz ibook (that I swapped when the topcase was being replaced with an Hitachi 5400rpm 60gig). I am completely bummed. These Fujistu drives are not only crap, but it seems entirely random if you will get one of them or an Hitachi and get the larger cache size. How picky am I? Wish there was some way to know when we are buying the machines which drive is in them... Just thought that was fascinating information that I had to share with other MR members.
