Sounds like your system needs some TLC. Overtime the drive builds up junk & gets fragmented both sap performance, Here's what I would do:
Start off by clearing out the old log and cache files which build up over time. There are a few apps that will work here here's one on the App Store: Disk Cleaner Pro.
The next thing on our list is to create a bootable external disk (HD or USB thumb drive) then boot up under it so you can run Disk Utility from it to repair the internal drives permissions & disk. Do make a backup before you do this just incase!
Then next thing here is to free up 1/4 to 1/3 of space on your drive. once done you'll need to defragment the drive. I use Drive Genius there are others.
After you defrag the drive you should see a lot more zip!

Thank you all for your answers. Just a little more info. So the computer was wiped clean (erased, erased free space, reformatted, and then OS X Yosemite reinstalled). Then around 700 GB of data was migrated to the computer. That fills up almost all of the space available, since it is a 750 GB HDD. Do you all think this is too much on the computer or something else?

i am sure that your computer have a bad hard drive and cable. if you want to make sure, you can download something call smart utility. if you mark my answer as chosen i would send it to you.
Good Luck!

Hey everyone! Thank you for the answers. I understand about the hard drive, the cable, and repairing the permissions. However, how much of the problem do you think is putting too much data on the computer?

Go Q! I don't have an easy answer here ;-{ The issues is not so much as too many files, but the constant deletion and adding of new files creates a 'churning effect' this is where the OS needs to finds areas within the disk to place the new or altered file. The more free space you have (1/4 ~ 1/3 as I recommend) allows the OS to be more effective in the files placement, but even then there is only so much the OS can do as over time. The areas available tend to be more and more fragmented and this is what slows your system. Upgrading Apps & OS's also tend to make things worse. As a good habit I recommend one defrays a HD once a year and more often if you do a lot of file churning.
