I proceeded as follows:
1. Connecting the Samsung SSD's USB SATA Adapter
2. Format (Mac OS Extended Journaled) the SSD with the Disk Utility
3. Cloning of the hard disk on the Samsung SSD with Carbon Copy Cloner - took about 90 minutes at about 100 GB
4. Turning off the system
5. Turning on the system by holding down the Option key. After a few seconds the Mac OS Startup Manager appears. Now select the Samsung SSD as to take-off volume and start Mac OS SSD. This then takes a little while, but one has to consider the possibility of whether cloning the hard drive was successful and the system behaves normally.
6. Turn off the system after testing
7. Open the MacBook Pro and the hard drive swap with the Samsung SSD - took about 15 minutes and is completely easy
8. Restart the system of the Samsung SSD - first start has required about 1 minute.
9. Check that all data / programs, etc. are present and shut down the system.
10 Turning on the system and stop right at the start the key combination "Command-Option-PR" pressed. So keep it pressed until the start-up sound can be heard for a second time. (Resetting the PRAM, the PRAM is stored specific settings, including the boot volume)
11. Restart the system takes in my case, then only 19 seconds.
12. Download the "Trim Enabler" program of [...] (free). Push start in the program folder, turn on Trim. In System report under "About This Mac" check if TRIM support on is "yes".
The bottleneck "HDD" in my 15 "MacBook Pro (Late 2011) is now eliminated. The programs start now much faster and total power is a smoother working become possible. Just fun !!
The performance of the SSD can be measured easily with the free program "Blackmagic Disk Speed Test" from the AppStore.
I hereby write reaching values of 392 MB / s and read values of 480 MB / S. That's what! The original was built by Apple disk write performance of 63 MB / S and read values of 65 MB / s. An immense increase.
