Haven't got one of these myself but have seen other people on this forum post that they have them in their MBPs, so yeah will be fine in yours.
 
fyi

HD = High Definition

HDD = Hard Disk Drive (spinning platter)

SSD = Solid State Disk Hard Drive

Just saying because I thought this may be a Hi Def post.
 
You may want to get the one without the G-Force shock protection as MacBooks have that built into the OS and the G-Force may cause issues. Plus you'll usually find the non G-Force versions go for a few dollars cheaper. I have a 7200 rpm 320GB Seagate drive in my alu MB and I haven't noticed considerable noise or vibration. And it's been as reliable as all heck. It all depends on how sensitive you are to the sound I suppose.

Oh, and just another suggestion, make a backup using Time Machine and do a full install of (Snow) Leopard and restore from TM. I found this works better than cloning the drive.
 
From what I understand the model number ending in ASG (ST9500420ASG) has a motion sensor that can cause issues with the uMBP's own motion sensor. I retrofitted my uMBP with an ST9500420AS model drive last month and I have had no operational, noise or temperature issues.

The ASG model is what Apple uses, and it came in my uMBP. I have no issues with the motion sensor.
