Hi guys, I guess this is a general question on SSDs. I just installed a 256 GB Crucial M4 in my 2010 mac mini. I transferred the old data onto the new drive and there was a big discrepancy (almost 11 GB) in the used space between the two drives. I then reformatted the old HD and cloned the new SSD on it. Same 11GB difference in used space. Am I doing something wrong or is this normal for SSD drives?
