    Hey everyone,

    Googling this doesn't really help (too many results that go back years), but I'm experiencing slow transfer speeds with my USB 3.0 drive in a USB 3.0 port.

    It starts at almost 100mb/s, then drops to 20-30mb/sec.

    It's being read from a SSD so there shouldn't be any read issues. It does this with EVERY file, not just some.

    Any blanket ideas?

    FYI - the USB socket isn't on the back of the motherboard, it is from the front of the case, but it is from the USB3.0 headers on the motherboard and the case USB slot is a 3.0 slot.

    Whats the specs on the HDD your writing to?

    It could depend on the write speed of the destination drive. Once the HDDs buffer is filled the speed drops.

    It's going onto a thumb drive. It's not a ssd or mechanical drive.

    thumb drives often have slow write speeds - regardless of what the interface is capable of.

    Unless its a quality USB3 drive, its likely to have pretty terrible speeds... I have a couple which are rated at over 100MB/sec which is great when you have to copy over GB's of .NEF photos

    What's the actual drive? is it a generic one, or something like a SanDisk Ultra Flair?
