I bought this recently for a new PC build. It has performed faultlessly and quietly so far. My previous PC used a similar Corsair unit and has been in use for over 10 years without a problem.

Would have been better with a second cable with SATA power connections. Had to use a molex to SATA adaptor to reach either end of the case.
Virtually silent.
Too early to rate reliability.
