After 11 months, the hard disk of the PS4 was full. Large howling - nothing could be deleted. So went in search and found at Amazon this plate. The reviews were encouraging this - so ordered. And indeed - the change was simply - using the tips of the reviewers. Before the data, make sure the load right software and after a sleepless night all the games and scores were back. Chill the plate is actually a bit faster than the original - but by no means slow. Therefore, the expensive hybrid drives are absolutely unnecessary. And to this disk is full, there's probably possible to connect separate plates or Sony sold the beautiful PS5.
