Today I received the SSD and installed directly and recorded my TM backup.
After that, I was thrilled! The boot time is only 30 seconds and Final Cut starts in 10 sec.
So the work is fun again;)
I still have to say that I unfortunately can not enjoy the full power of the SSD since this is only achieved with SATA III.
The MBP from 2010, but only SATA II.
My values:
-------- Write -------------------------- Read
approximately 210 MB / sec -------------- approx. 265 MB / sec
So I'm perfectly happy;)
