    Anybody found out what transfer speeds can be acheived to/from the internal storage in the OP6?

    Looking to find out read speed, write speed and what the fastest connection method is (USB client, USB OTG, SMB/FTP/SFTP/DLNA via 5GHz wifi etc).

    I don't have the exact speeds, but I transfered a couple hundred MB to my OP3T and my OP6 and it went significantly faster.

    What did you use for the transfer (USB or WiFi)?

    Transferred my music about over 6gb, it took the same time as on my nexus6 via usb. On my laptop has been used usb3.
    Huge shame on oneplus using over 5 years old technologies.

    I'm trying to figure out if its worth buying the 256GB or is it a waste of money, cos it would take so long to fill / backup.

    I can work out the theoretical transfer speeds of USB and WiFi which are about 35MB/sec for USB2 (something about dash charge limits it to USB2) and 176MB/sec for 802.11ac 2x2Mimo. But the link between the router and the client is gonna be capped at 1Gbps, so that becomes 120MB/s.

    In the 256GB OP6 the SSD chip has a data transfer speed of 850MB/s read, write speed is 255 MB/s. So the limit will probably USB/WiFi speed.

    So lets say at best, half of 802.11ac speed which is 60MB/s. So it would take 256,000/60 seconds to transfer the entire storage, which equals 24,266 seconds or just over 71 minutes. Over USB the best speed will again be half maximum speed so 256,000/18 seconds which equals 14,222 seconds or 3hours 57mins.

    And those speeds are before the OS and firewalls get in the way.

    Is anyone able to do a timed test to prove this maths wrong?

    BTW current Sandisk 128GB uSD cards have 100MB/sec read speeds, which I have achieved in a USB3 card reader. So if Oneplus installed uSD slots in the phones, they wouldn't be the bottleneck its been claimed it is.

    Yeah, current technologies in 2018 are slow stone age.
    But for example in my case I do not need to copy entire storage on daily basis, at least the have of phone storage will be occupied with data that doesn't required to be backuped and the rest of the storage will be used for daily usage in and out.
    In that case it is basically only over 120gb need to be backuped once in a while.

    The current phone nexus6 had only 64gb of storage and so tire to struggle to get it full.
    damn, if I could I would buy 1tb version.
