OK, hope that you find what's needed!
Sign up for Newegg promos & you'll always get great deals, recently there was a 1TB Seagate SSHD for notebooks at a killer price of $49.99 w/free shipping. Had I needed one, would had jumped all over it, but all of my notebooks, except an IBM T42 ThinkPad, runs SSD's, in both the stock & optical drive bay via a $10 adapter. If I need an optical drive, have a couple of USB to SATA (optical drive type) cable, works perfectly when needed. Speaking of Newegg, I cannot possibly begin to total the amount of cash that's been saved over the last 7 years, yet would bet that it'll make a
huge down payment on a new truck.

So if you really want to expand your storage, that's an added option, just find the proper size for your notebook, most of mine takes the 12.5mm, another with a slot load takes a slimmer model.
Good Luck with your project, I feel confident you'll find a suitable HDD to meet your needs.
