The fw800 only has 33MHz PCI slots but they are 64bit capable. That means that a 32bit PCI card would clock a maximum of 4 bytes every 30.3nS or 132MBytes/s. I guess that's fast enough for an ATA/100 drive, and about the same as a 1.5Gbits/s SATA drive. However, it will limit a newer 3Gbits/s SATA drive, unless you can find a 33MHz/64bit SATA PCI card, which I don't think anybody makes. On the other hand a pair of raid striped U160 SCSI drives attached to an ATTO UL3D 64bit PCI card could max out at 264MBytes/s and could be spinning at 15Krpm! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
