    EXt USB2 1TB disk faster when converted to GPT


    Hi there
    Just running some tests on three average external USB2 HDD (self powered) 1TB drive -- Thicker older WD model -- not the Passport type but still self powered.

    On a USB2 connection the data transfer still around 50% FASTER than when formatted with standard MBR.

    Unless you NEED the older MBR system I can't see ANY disadvantages to making all my disks GPT where possible - except for the small SSD I have as my Boot disk -- even on a non UEFI system (where a GPT disk won't be bootable - but perfectly fine for DATA etc).

    Anybody who knows any reasons for NOT converting -- please post as from what I can see it's WIN in every way -- and gets round the stupid 4 primary partitions for MBR drives and also is compatible with my larger (> 3TB) drives too.

    Cheers

    What speeds were you seeing before and after? How are you testing, with a stopwatch or what Windows claims the transfer speed is?

    I'm confused...is it faster with MBR or with GPT? Post header says one thing and in your post is says the exact opposite?

    Nope. All good.
    Read again: text says GPT is faster.

    Will this speed rule be of practice for internal drives too? Or is it for external USB (2.0 - 3.0) only?

    I didn't felt any difference because new machine has all disks in GPT. But will try it out when I get the chance on older machine: converting to GPT means backup data first because it has to be wiped out to convert the disk.
