At present I've 750GB HDD and I just got OCZ Agility 3 2.5" 240GB SATA III MLC Internal Solid State Drive SSD (AGT3-25SAT3-240G) from Newegg http://www.newegg.com/Product/Product.aspx?SID=u17800t0f0fp69042dd0c0s701&AID=10440897&PID=1225267&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-cables-_-na-_-na&Item=N82E16820227727 I got this caddy from Amazon to do a data doubler by moving my existing HDD to DVD drive slot and getting rid of DVD drive http://www.amazon.com/Drive-Unibody-MacBook-SuperDrive-Replacement/dp/B0058AH2US/ref=sr_1_1?ie=UTF8&qid=1329269297&sr=8-1 I've Lion installed on my system 2 weeks back and I regularly do TM on my MBP. At present my 750GB HDD is divided into 250GB for all my OS and program installs and 500GB of all Data install. At present there is 70GB free space on primary OS partition. I've got Carboncopy cloner which I use from time to time to backup between drives. So what should be my way of transfering all my data from primary OS partition onto SSD ?
