Is WD Caviar series (WD20EZRX) optimal to use 24/7?

I wanted so much to know if the WD Caviar Green series is a line to use 24/7, ie whether it is durable and sturdy to withstand years on.

Because the site says: “WD Green hard drives are designed for use as secondary drives in PCs, for external enclosures and other applications for which low noise and low heat are beneficial.” That means he is not so reliable to operate 24/7?

Tnx in advance.

that drive is not tested to run 24/7

12hours a day maximum

but like every drive some last some dont… its a gamble and good luck
