Forgive me, I should have trimmed the quote a bit more. I was responding specifically to the "many mother boards have hardware RAID support available through the bios" part, not the lsi part. > Odd, my MegaRaid controller takes about fifteen seconds > by-the-clock to initialize and to the integrity check on my single > initialized drive. It is almost certainly spending those 15 seconds on something else, like bootstrapping its firmware code from a slow serial eeprom or waiting for you to press the magic key to enter the bios utility. I would be very surprised to see that time double if you add a second disk. If it does, then they are doing something *very* wrong, and certainly quite different from any other real or fake raid controller I've ever used. > It's amazing that with a fail and retry it would be _faster_... I have no idea what you are talking about here. I said that they aren't going to retry a read that *succeeded* but came back without their magic signature. It isn't like reading it again is going to magically give different results. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) iQEcBAEBAgAGBQJUblBmAAoJEI5FoCIzSKrwFKkIAKNGOGyLrMIcTeV4DQntdbaa NMkjXnWnk6lHeqTyE/pb+l4VgVH8nQwDp8hRCnKNnKHoZbT8LOGFULSmBes+DDmW dxPVDTytUu1AiqB7AyxNJU8213BQCaF0inL7ofZmX95N+0eajuVxOyHIMeokdwUU zLOnXQg0awLkQwk7U6YLAKA4A7HrOEXw4wHt9hPy/yUySMVqCeHYV3tpf7t96guU 0IRctvpwcNvvVtt65I8A4EklR+vCvqEDUZfKyG8WJAeyAdC4UoHT9vZcJAVkiFl+ Y+Mp5wsr1vuo3dYQ1bKO8RvPTB9D9npFyFIlyHEBMJlCHDU43YsNP8hGcu0mKco= =AJ6/ -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
