Windows 10: 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!

Transferring files

I am transferring files from my old computer (Toshiba Windows Vista) to a SD card that will permanently be in my new computer (Acer Windows 10). All of the files (70G) I need are currently on an external hard drive. I plugged the external hard drive into
my NEW computer, all the files are there & readable (able to be opened). Then I put the SD card (512G) in the NEW computer & format it. Then I try to copy & paste my files from the hard drive to the SD card, I can only copy so many files before I get an error
message saying the file on the hard drive is corrupted & cannot be copied (even though I can open these same files directly from the hard drive with no issue). So then I tried to plug in the hard drive & SD card into the OLD computer; all the files on the
hard drive are there & readable, the SD card cannot be read & my OLD computer wants to format it again. I format it (which deletes everything on there) & copy a few files over. Then I put the SD card back in the NEW computer, again the card cannot be read
& the computer wants to format (which deletes everything again). I've done this back & forth process a few times with the same results. How can I get ALL of my files from the hard drive to my SD card & have my NEW computer read them?

 

Slow sync with WMP11

I have an iPAQ hx2790b and i am running Vista 32bit ultimate and WMDC 6.1.



Everything runs perfectly and it syncs with everything i want it to. There is however an issue relating to sync of media files in WMP11 to an SD card in the iPAQ.



The set up is fine but when it goes through the process of transferring files to the SD card in the iPAQ it is painfully slow indicating it is transferring aty USB1.1 speeds not USB2.



Has anyone experienced this issue? Much faster to put the SD card in a reader and sync directly to the card...

 

SD cards are usually always painfully slow nothing you can do about it unless you spend about 10 times the price and get the faster ones.

From what I remember the fastest I have gotten is around 8 MB/s on the cheaper type, I have never used the more expensive ones.

Here are the speed class marks.
Note: You probably have a class 10

 

I have SD cards labelled as Class 10 U-I 45 MB/s, under testing with small files I get a writing speed of 18 MB/s. Thus meeting the min spec of such cards.
I won't buy anything slower than that, or from dubious suppliers.

Also worth checking cheap Cards for capacity fakes, I use H2testw 1.4

For your amount of data on my Cards it would take roughly ~60 min to write.

 

I have the same problem when transferring music from my C: SSD drive to the memory card slot in my laptop. Unfortunately, the memory card slot only runs at USB 2.0 speed. I resolved the problem by connecting the SDHC card to the laptop in a USB 3.0 to SDHC adapter, through the USB 3.0 connector. BINGO! The writes to the memory card increased from a few hundred KB per second to 8-10 MB per second. I even found a bargain on the adapter on Amazon here: https://smile.amazon.com/gp/product/...?ie=UTF8&psc=1

Happy copying!

 

OK, but all this talk of the speed of SD writes doesn't address when the speed is 4-5 KB/sec. I could live with 1 or 2 MB/sec. I have two Dell laptops running Win10 with all drivers updated and that is the speed of SD writes I'm getting on both of them with their SD slots. Both are using Class 10 SD cards. I can boot to Linux on a flash drive and get those MB/sec transfer rates. So what is Win10 getting wrong here?

 

Try to shut down your AV (If running Defender, then also shut down Smart screen) ! When transfer files to/from USB/SD-cards
AV's are often the cause of slow down!
