    I would leave it as is, YMMV.
    GPT formatted SSD with a EFI system partition and UEFI boot set in BIOS can shave lots of seconds off your boot time compared to a MBR boot. Just GPT by itself will save you nothing (but does provide redundant partition info which MBR doesn't).

    Hi there

    GPT will be mandatory for partitions / HDD's > 2TB if you want to use the WHOLE HDD. Provided you have say a second HDD say a small capacity SSD which you can use as a boot drive then there's no problems using GPT on computers that only BOOT via MBR (I.e no UEFI mode in the BIOS).

    So if your computer is MBR then I'd see if I can isolate the OS and put it on its own HDD - a good idea in any case - and have GPT for any other HDD's.

    Note you CAN convert MBR -->GPT without losing data -- but NOT the other way around.

    I think also if you are using XP or some versions of W7 for "dual booting" you can't boot these OS'es from GPT HDD's even if you have a UEFI Bios.

    If you are using an SSD for BOOT -- the boot process is fast enough anyway -- a few millisecs here or there is an irrelevance.
