Since I have the 200GB SATA HDD i am trying to get working via SATA to IDE adaptor, I have Tiger Installed on the 200GB HDD and have noticed that it is in deed much faster than Leopard. My Leopard Install is on a Hitachi Deskstar 60GB IDE HDD at 7200RPM. Inside the mac I also have a Hitachi Deskstar 40GB IDE 7200RPM HDD. The other two drives Are 80GB 5200RPM HDDs on the ATA66 bus. One is a Maxtor (from another TiVo) and one is a Seagate. The Seagate was inside the eMac until I replaced it with a 80GB WD 7200RPM from a Tivo. I have noticed that there is no difference in speed compared to booting Tiger or Leopard on ATA66 vs ATA100, Nor have i noticed ANY difference whatsoever in preformance running Leopard on a 7200PRM vs 5400RPM on my eMac. So the point in this post is this: What difference would it make having Leopard or Tiger on the ATA66 bus? One of the drives i plan to put Tiger and Linux onto one of them (not sure if ill use the 7200RPM 40GB Hitachi on the ATA100 bus or a 80GB HDD on the ATA66 bus.) Also on a Note of Linux on PowerPC: Has anyone tested the Mate Desktop? Is it faster/better than LXDE? I have used Ubuntu, Kubuntu and Lubuntu on the MDD in the past but have yet to try MATE. I have NEVER had any luck at all Playing YouTube on PowerPC Linux. Does HTML5 work on it? (When i did the forte into PowerPC Linux YouTube didn't HAVE HTML5 yet. I can use VLC if need be with Windows and Mac but never tried PowerPC Linux in that way. Also a problem with Linux on PowerPC with me is that 3 main programs I use do not work on PowerPC Linux. Those programs are: Skype, Spotify and RockBox Utility. Not having the ability to use Chrome on PowerPC (or Chromium for Linux) doesn't At all bother me I have become more accustomed to Firefox (TFF on PPC of course). Leaves me to yet another related question that i cannot find a answer too: Mozilla stopped providing Firefox to PowerPC at version 3. Opera stopped providing a PowerPC Broswer at version 10. How come it is that while these two browsers are outdated and unsupported on PowerPC OS X, They are at current version and work COMPLETELY on PowerPC Linux? If They can be made to work on PowerPC Linux, How come Mozilla and Opera won't still make PowerPC bowsers for OS X but they work on PowerPC Linux?
