In real world testing my 750GB WD Scorpio Black 7200RPM performs the same as my 1TB WD Scorpio Blue 5400RPM in my media center 2011 Mac mini which is often recording 6 HD streams and playing back 2 HD recordings or H.264 m4v's. The Scorpio Black is faster on the edges, but the middle of the drive is the same performance. One thing to note is that this is the 9.5mm model. 12mm 1TB drives will definitely be slower because of lower rotational speed and density.
Got a tip for us?

750GB at 7200 RPM or 1TB at 5400 RPM?

not if I still want my optical drive, and especially not if I want everything on 1 drive
I personally value the space over the speed for my current applications. COmes down to what you need. If 750 is overkill, then dont get 1tb

To the OP: 1TB > 750GB. End of story.
For those who say 7200rpm is better: the difference between 5400rpm and 7200rpm isn't anything to write home about, especially on these 2.5" hard drives, and they are all far too slow compared to a Crucial M4 in any case...

WD has 2.5" 9.5mm 1.0TB drives. 5400rpm.
This guy is just a wealth of information. I learn something every day.

Well you can't have everything in this world. You've got to compromise at one point. So you can have 2 drives with speed and storage but no OD, or you can have 1 drive that's slow with lots of storage and an OD, or 1 drive that's fast with little storage and an OD. Pick one of the three. For me, it's a dead giveaway. 2 drives with the ODD in a slim external bay for easy transportation so that if for some odd reason I would need to use the ancient medium, I have it right there.
That used to be true when good performance SSDs used to cost well over $3/GB, for not a lot of room after the 7% conversion, and the advice du jour was to put the OS and frequently used apps on the SSD, while leaving the HDD to store everything else.
Nowadays SSDs have gone under $1/GB, especially that 512GB M4 deal these days, so its safe to put more than the OS and apps on the SSD itself.
The original thicker 1TB is still available at a lower cost. If the OP is shopping he should be aware there have been to variants of the same drive capacity. The thicker 12mm drive is considerably slower.
Yes, that's true. There are a small minority of people who actually use their optical drive on a regular basis. I wasn't speaking to them. As for the single drive, does it really matter?
750GB at 7200 RPM or 1TB at 5400 RPM?
I dunno blokes,
I got myself a 15" 2012 macbook pro 2.3 GHz 500 gig 500rpm hd with 4 gigs ram. Now here's where the fun starts. I called OWC and picked up 2x8 gigs of ram + a momentus xt solid state hybrid hd 7200rpm 750gig the reason it's a hybrid is because it has an 8 gig ssd attached and this baby flies. Oh I also bought a external hd case to put my original 500gig HD in.
I do quite a lot of adobe from after effects to photoshop etc and she purrs at about 4500rpm at 50f

This definitely. It is the best solution for speed to storage ratio.

What did the OP get I wonder?
Also, Does anyone know and check the Apple System Profilers for me?

Not always.
Store 500gb of data on both and the 1gb will likely be faster due to short-stroking. It will also remain fast for longer, due to less fragmentation as space gets tight and the inner tracks start getting used.
That said, a momentus XT 750 will be faster than both.... and yes I went for one myself due to not wanting to manage SSD storage (everything on one drive).
+1.
7200rpm is faster 1:1 storage and 1:1 generation.
Scorpio Blue 1TB is only 10mb/s below Scorpio Black 750gb, and it has less noise and less power consumption.

MB/sec isn't the full story either.
If you only have to move the read/write head half as far (half the disk's tracks on a larger capacity drive storing the same amount of data), then random IO suffers a lot less.

IMHO, you should purchase whatever comprises the default/cheap config then replace it with an SSD. Sell the high density but-still-slower-than-SDD 5400.
