Fairly recently - maybe in the last few months - but it's hard to tell,
the disk performance has dropped through the floor.
First, make at least two complete back up sets and store one off-site.
It could be a hardware problem.
Your hard drive manufacturer should have a diagnostic utility available
in the form of a bootable ISO image. I'd download, burn, and boot that.
If the diagnostic finds a problem, proceed accordingly. Understand
that other issues may make a good disk look bad (power supply, power
cables, motherboard, controller card, data cable, etc.). If the utility
finds no problems, then I'd wipe the disk using the utility, do a fresh
install, and then restore/ reconnect data.
As an aside, I use one disk for swap and the root file system, and a
second large disk for data. Then whenever I do a fresh install, most
restoring data is a simple matter of hooking up the data drive.
