    I own a Lexar 32gb usb 3.0 flash drive. The specific flash drive I have is in this link: Newegg.com - Lexar JumpDrive Triton 32GB USB 3.0 Flash Drive Model LJDNV32GCRBNA. Now it has advertised speeds of up to 155MB/s read, 150MB/s write. Now I know that i might not get 100% of the suggested performance but I don't get anything near those speeds. Highest I've seen transferring files from it to my laptop and vice verse is like 30mb/s. What gives? I am positive that my laptop has usb 3.0 slots so that's not the problem. Any chance I would need to download new usb 3.0 drivers or something since I recently just upgraded to Windows 8 Pro?

    Thanks! All suggestions are welcomed and appreciated.

    Hey there,

    I also have a 32 GB USB 3.0 Flash Drive from PNY and on my HP Envy 15 I get a max of about 49MBps. I believe that the issue is that we are transferring from slower hard drives and not anything to do with a malfunctioning drive or driver. It's more to do with the bandwidth of the flash drive being huge while the read speed of the source file is miniscule. If you had an SSD more than likely your speeds would double.

    That said, you are getting about 40% slower speed than I am, so you could also have a driver issue or it could be a bad speed rating on your flash drive,

    Thanks for the reply. What you said makes a ton of sense. I might have to invest in an ssd. If my issue was a driver issue, since your getting way better speeds than me, how would I troubleshoot that?
