I am considering buying a 13inch MacBook Pro and selling my mid2010 mbp. I bought a 500gb SSD for my MBP. I was hoping to just take it out and switch it with the sata drive that comes with my new MBP. However, I am concerned that the drive format or something may be the reason my current MBP is quite slow and therefore putting into the new one would not change anything and in fact slow down my new mac. Should I maybe back everything up to another drive and reformat my SSD before installing it? Or would it be ok just putting it in as is? Thanks for any responses.
