I got one last year, a seagate one, i had a load of problems with it, but then it is seagate after all and I normally avoid seagate.
When I got it working it was ok, not sure if it was that much faster than a normal drive. i now got it as a second drive with a SSd as the primary drive.
As been said above, the drive decides what files are used most and move them to the flash part, in theory.
In a laptop it is problem a good halfway house between capacity of a spinny unit and the speed of a SSD.
