This is now my 2nd Crucial SSD. Again the replacement of the existing notebook SSD worked without problems, the supplied (or by code unlockable) software is working properly. Even the replacement of a 1 TB HDD with a SSD 512 has so worked out, also including the operating system Windows 8 on the boot partition. In addition, I strongly recommend buying an adapter to connect the SSD temporarily for copying to the USB port.
The speed is enormous compared with the previous hard drive.
