Questions about WD Red

As far as we know, it should work. But it has only been designed for 4TB hard drives (which doesn't necessarily mean it won't work). So we can't say 100% yes unfortunately.

Have you found the information you need in the meantime? I am sure that if you research the whole thing individually on the internet (possibly in English) using the appropriate keywords, you will find a suitable answer.

Yes. Note from Snyology: This drive is only compatible with Synology NAS models with hard drive tray shipped since June 2014. Please check if your model was shipped after the above date.

I installed it in my old Qnap four-disk NAS with other machines running next to it and didn't notice any noise level difference.

Unfortunately, we in the community cannot answer such a question. The questions, answers and discussions should explicitly refer to the products and their function. General questions about orders, delivery times or prices should be asked directly to the customer service. digitec@digitec.ch +41 44 575 95 00 Monday - Friday: 09:00 - 18:00 Please note the community guidelines: https://www.digitec.ch/de/Wiki/4490

Yes, of course :-)! Even if it would "run all the time" (i.e.: as intended) - what does it mean to "run all the time"? The disk goes into sleep mode anyway, so it's stationary. It would be stupid not to be allowed to switch it off ;o)!

ps: The 6TB would also do in terms of capacity...

They should run without problems on any Sata port.
