When a magnetic hard disk is used, what solution can help improve file read/write speeds?
Reimaging the disk
Killing background tasks
Defragmentation
Rolling back device drivers
Defragmenting a hard drive means rearranging the data as saved on the disk so it is in a sequential order. If you imagine a magnetic drive as a sentence, multiple files would read something like "Create file1.txt; Create file2.txt; Add data to file1.txt; Create file3.txt" and so on. Over time as more files are created and updated each file's data is spread out throughout the disk and the drive becomes slower. Degragmention rearranges the files so that the data is sequential: "Create file1.txt; Add data to file1.txt; Create file2.txt; Create file3.txt" and so on. By grouping each file's data into the same area of the disk the performance improves greatly. Solid State Drives (SSD) do not need to be defragmented.
