Some experimentation on my Dell Inspiron 530 shows the following: Booting with controller set to RAID mode: - boots OK without the need for the all_generic_ide parameter - read speed: 64.0 MB/s - write speed: 51.4 MB/s
Booting with controller set to IDE mode: - requires all_generic_ide boot parameter to boot correctly - read speed: 65.0 MB/s - write speed: 51.1 MB/s Read/Write tests performed on an ext3 journaled file system with a 4 Gb file using dd - I suspect if I was to repeat these tests more scientifically on a raw device the figures between IDE and RAID will be small and insignificant. I recommend setting the BIOS to RAID mode just so that one does not need the "all_generic_ide" boot option -- Dell Inspiron 530 SATA drive not detected in IDE mode https://bugs.launchpad.net/bugs/153702 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
