Ok, the problems are back and it HAS to be the drive. Will this work in my Mid 2010 MBP Version 7,1 running Snowy?

Western Digital 750 GB WD Black SATA III 7200 RPM 16 MB Cache Notebook Hard Drive WD7500BPKX?

I presently have a WD7500BPKT in it. Is the newer one going to be of any advantage or should I just replace what I have?
