Quick questions with answers that I haven't yet discovered from several document and internet searches. I just received a 2 x 1.25 GHz PM G4 (10.4.5) and more RAM & an IOGEAR USB2 card is on the way. In the meantime, here are two questions. #1 - I want to increase the hard drive speed, so I am looking to get this SATA hard drive controller by SIIG. It says it supports 150 MB/s transfers. Is this drive by Samsung compatible with the controller? The Samsung has specs of 300 MB/s transfer, but I am unsure if it is backwards compatible. #2 - At work we have iMacs that ask for login information when the machines wake from sleep. I have scoured Sys Prefs and Apple support docs for how to do this and have found nothing. It would be a great security benefit for me to have this feature and I am wondering how it is done. Ok. Thanks in advance.
