Explanation
The progressive worsening of file open/save times on a drive that is otherwise healthy strongly points to file fragmentation. On traditional HDDs, fragmentation occurs when files are written in non-contiguous blocks across the disk. As the drive fills up (indicated by hundreds of GBs of files being backed up), fragmentation worsens because there is less contiguous free space available, forcing files to be split across more distant locations. The read/write heads must then seek to multiple locations to access a single file, significantly slowing operations. Running a defragmentation scan (and subsequently defragmenting) will consolidate file data and improve performance. Installing drivers (A) and running chkdsk (C) address different problems - driver issues and filesystem errors, respectively. Reformatting (D) is a last resort and unnecessary when the drive is healthy.
