Copy Files from Hard Drive to SD Card - Painfully Slow Transfer

    I am in the process of transferring files from my laptop's hard drive to a 256 GB SD card in the laptop's card reader slot. The transfer started quickly but then it slowed down drastically and has stayed down since. I've looked at some similar posts and tried a few of the fixes that worked for others but none of them have worked for me and I'm still transferring at an incredibly slow pace.

    I should note that I'm transferring music files from my computer to the SD card. I have about 50 GB that I would like to put on the card but it would take me a week at the rate it's going now.

    Anyone have any suggestions?

    THANKS!
    For me, the thing that worked was going into the SD card properties and selecting "performance", versus quick removal. I rebooted and the speed increased dramatically. This is the only thing that has worked. Apparently, that setting in Windows throttled the performance!

    Usually, it happens with the SD Card to sending data from one place to another in our system, I would suggest you use a high-class SD Cards Like - Class 10 or UHS Class cards which are more powerful and faster than our normal cards, I know these cards come a bit expensive but Its totally worth it buying.

    Had the same problem transferring photos. Not big ones, just a lot of them. I disconnected my internet connection (offline) and they went very quickly. Must be trackers, clouds, algorithms, Norton, Windows, Adobe, etc. communicating our every move. Anyway, went from an estimated 11 hours to less than one hour. Hope this helps.

    I had a copy of 20 Gigabytes to a hard drive and unfortunately the SD adapter was generic, so I look for a better quality so that the copy has been completed.

    For backup purposes I advice using an external hard drive rather than backing up to SD cards or USB thumbdrives.

    Hi there
    you could try I suppose to put the SD card into your phone (assuming you have space for a micro sd card) and then use the phone via usb to transfer to windows HDD / usb or whatever.

    The slow rate might not be down to the card itself but the reader -- these are often very slow devices especially if your computer isn't the newest of hardware or using one of those SD-->micro sd adapter things which you then insert into the computers internal card reader.

    The phone's read / write system could be quite a bit faster - in any case the phone being an active device can buffer the I/O increasing the throughput. Worth a try if your phone has a slot for a micro sd card. Android itself being essentially a Linux type system has better I/O handling than the rather dated Windows NTFS system and the even more dated FAT32 system - you won't lose data on the card as Android /Linux etc can read / write NTFS / FAT32 these days.

    I agree though the Linux transfer goes much faster than Windows -- did a test with around 32GB music -- the SD card shows up in linux as /dev/mmcxxxx and once mounted the SD card transfers were running at about 8Mb/s while on Windows the same card was giving speeds of less than 1Mb/s -- so I agree Windows isn't the best mechanism for using micro SD cards !!!!.

    I'd recommend an external 256GB SSD -- connect via SATA-->USB connector -- nice and fast --and these days there are some really good value deals to be had on SSD's as people migrate towards the newer NVMe types (the ones that look like computer memory chips).

    Cheers
