Will this hard drive work on my Dell Inspiron 15R?

[BakerFanBoy52]

I have a Dell inspiron 15R N5110. To keep it short, the hard drive died. I talked to Dell, and they told me this:

"The Inspiron N5110 system uses Serial-ATA II hard drives and is a Field Replaceable Unit. All the drives are available at 7200 and 5400 rpm drive speeds along with FFS.
The hard drives compatible are 320GB, 500GB, 750GB"

Okay, I am not very bright when it comes to this stuff at all. I do not have much money this month. I am planning on getting something better in a few months, but for now I just want to get my laptop working again.

I found this hard drive, and I am just curious, will it work?

Seagate Momentus ST3500641AS 320GB SATA

Capacity: 320GB

Speed: 5400 RPM

Cache: 8MB

Interface: SATA 3.0Gb/S

Drive Size: 2.5''

SKU: 26024

I looked over this and I see that my laptop has a SATA II motherboard, but this hard drive says the interface is "SATA 3.0Gb/S." I will be honest, I have no idea what that means, but to me, it sounds like it isn't compatible with my computer.

I guess to get to the point, I am just asking, will this hard drive work on my laptop?

Thanks in advance!

Yes it will work.
SATA II = SATA 3.0Gb/S
