hey all, I've had 2 different SSD's in my MBP so far and neither have worked. 1) OWC Mercury Electra SATA6G SSD - This seemed to work like a charm but every hour or so, my MB would hang for around 30-45 seconds - literally every hour. I returned it for a refund. 2) ADATA SSD S510 SATA6G SSD - Followed the same steps as I did above, used "SuperDuper" to clone the drive - switched on the notebook but the apple sign went to a folder with a question mark and then a no entry sign. I wiped and cloned it again (and a third time), all 3 times I booted into recovery and did a repair files and permissions. While doing so the MBP was running incredibly slow. Nothing worked it would not boot into Lion. I tried installing Snow Leopard from the install DVD and this worked but it was running like it had a 500RPM hard drive in it, totally un-usable. Has anyone successfully installed a SATA6 SSD into their 2011 MBP 13"?
