SATA2 HDD compatible with early Macbook?

[cvzyl]

The HDD on my early model Macbook (think it's a 2006 model) failed.
Apple quoted me a ridiculous amount to replace it. I had a look on iFixit's website and the HDD replacement on the Macbooks seem pretty simple.
However, it seems like SATA drives are not common yet, SATA2 drives are more available (and even SATA3).

I can get SATA2 and 3 drives in sizes ranging from 250 Gb up to 750 Gb for reasonable prices. Will the SATA2 drives work in the Macbook? What is the limit on drive size? Would a 750 Gb drive work?

Thanks in advance

Yes, it'll work. Newer SATA drives (e.g. SATA2 or SATA3) are just capable of transferring data faster on newer SATA controllers. It's all backwards compatible--so much so that you can still just call it all SATA.
