Quick test I performed.
I copied 2 files over to the card, about 200 MB each, deleted those, then copied over 3 more files, again about 200 MB each, and then deleted those also.
All of this was done without any issues.
HDD: Western Digital 750 GB WD Black SATA III 7200 RPM WD7500BPKX
RAM: Kingston 8GB 1600MHz DDR3L (PC3-12800) 1.35V Non-ECC CL11 SODIMM KVR16LS11/8
OS: Windows 10 x64
CARD: Transcend 16GB SDHC Class 10 Flash Memory Card Up to 30MB/s (TS16GSDHC10E)
I actually suffered the same problem with USB 3.0 devices. I then found out that the issue was that I was using a USB 1.1 Hub for the mouse and keyboard and either it was not working well or it is not supported. Removing the USB 1.1 Hub solved the problem, at least for USB 3.0 devices, I'll check with the SD card later.
Can you Check under Device manager for any error? or test selecting the option to update the driver.
There is some information I found how to remove the read-only, How To Remove Write Protection From Micro SD Card Using CMD.
