From what I've been able to locate, the existing drive is a standard

With that in mind, you could use any SATA 7200 RPM drive that is also
2.5 by 7mm in size.
Here is one that is also 500GB and runs around $50.

You might also consider upgrading to a SSD drive like one of these

if speed is your only concern. It is also a drop in replacement for
what you currently have. Then you don't have to worry about bumping
the laptop and crashing the drive as the SSD has no moving parts,
runs cooler, and takes up much less battery usage as well.
You are right, after downloading the manual for the Dell computer, I
found the hard drive is 7 mm thick.
I have decided to go with another Seagate like the one in it, except it
will be an SSD. It's sixty five dollars, pretty cheap for an SSD.
I think I need this ST500LM001 model, but I'm not sure.
What does it mean when the drive has encryption?
My existing drive is SATA 3Gb/s and the drive I'm looking at is SATA
6Gb/s, does it matter?

The difference in interface speed will not matter as the newer 6Gb/s is
downward compatible, much like USB3 and USB2.
The self encrypting drive means that the data encryption is built into
the hard drive or SSD interface controller. This is an anti-theft
feature that means if I pull your hard drive out of your PC I will not
be able to read the data from any other PC, with out your access
password. Give this link a read and remember to replace SSD for hard
drive as you read it.

The other thing is that if you wanted to encrypt the drive using an
older non-encrypting drive your PC had to spend CPU time
encrypting/decrypting the data all the time. With a SED drive it is
built into the drive and your motherboard and CPU don't have to be
slowed down doing the encryption/decryption.
