Occasionally makes some noise/beeping (compared to before when I only had SSD installed). Came well packaged, but with no instructions on installation (it was my first time installing a HDD so I was a bit confused why it had 3 ports and whether I needed to plug into all of them, but I gather this is support for both older and newer power connection types). Overall I'm happy, but it'd be too soon to make comments on its long term health/reliability.
