    Question Are Hardware RAID operating system specific?

    Same RAID hardware. Are they interchangable between Linux and Windows?

    Subject: No.
    Body: Yes.

    Assuming the file system is readable by both Windows and Linux... a hardware RAID controller presents the array as a single device to the operating system. Any operating system can see the drive, but if you've formatted it with Ext4, you're going to have trouble actually reading it in Windows

    Asking opposite questions in the subject and body is somewhat less than genius
    [GB ≠ GiB] [MB ≠ MiB] [kB ≠ kiB] [1000 ≠ 1024] [Giga ≠ gram] [Mega ≠ milli] [Kelvin ≠ kilo] [Byte ≠ bit]
    There is no millibit. There is no gram-bit. There is no Kelvin-Byte.

    A provider is telling me that they have hardware RAID for Windows but not for Linux, don't the same RAID hardware work for both types of operating systems?

    That's probably because they are using on-board RAID on the motherboard.

    If they are saying that I would ask what exact RAID card they are using, I am not a big fan of most of the onboard raid and you would probably just be better off going software raid if that was the case.

    I am going to use software RAID1. This server does not have hot-swap ability, so if 1 hard drive dies, there will be downtime which is the time it takes to replace the hard drive?

    While the RAID1 array is rebuilding after a hard drive crash, will I experience any downtime with my websites?

    You won't experience downtime during a rebuild unless the other disk dies.. but you will experience plenty of slowness.

    It does not have hot-swap, so yes you will have downtime of about 15 minutes for them to replace the HDD.
    Then the array has to rebuild which can take a few hours or many hours and will have a bit of slow down in performance.
