Maxing out Hard Drive Space

I saw where you can put in 1.5 gb of hard drive space on a Dell Precision M6600, I found it a little unclear, so does that mean I can have a total of that much, or can I put 2 1.5 gb hard drives in it. I'm trying to decide whether I wanted to put 2 1tbs in it or am i limited to maybe 2 750's + my 64 ssd mini? Let me know something people! Thanks

 

Depending on height of caddy.
As far as I know, 1tb drives are 12.3 mM tall.
If your laptop supports 12.3 then you can have 2tb storage.

 

You could put in 2x1TB drives if you don't mind trading slower rotational speed for more capacity.

Samsung HN-M101MBB's are 1TB 5400rpm drives in the 9.5mm height that fits in the M6600.

 

Are there any 1tb drives that are 72k rpm? I decided to not risk the chance of them not fitting and went with 2 750's. I'm trying to take it in steps, next is to figure out what to format them as if i'm going to have a split partition of Windows 7 and MaC OS. Thanks

 

There is no 7200rpm 1tb drives fitting for M6600.
If you are going to max the capacity, you may take advantage of the optical drive slot by replacing DVDRW with a hard drive adapter.
