This hard drive series initially passed our lab compatibility test and was included in the recommended HDD list. However, during the last few months, we have received an overwhelming number of support requests regarding this hard drive series. The high failure rate of this hard drives series has raised concerns over risks of data loss. Therefore, we have no choice but to remove this series from the recommended HDD list. For users who have already installed this series of HDD on their Turbo NAS, QNAP will continue to provide technical supports as requested.
