In principle, yes, but you should consider that in a RAID 1, the weakest component always sets the clock. When setting up a new RAID, everything goes well, but at a later point in time, there may be additional problems. My recommendation: Take two disks that are exactly the same.

We source our products from different suppliers to ensure availability as far as possible. As soon as a supplier does not have the item in stock, we switch to a supplier with higher availability. Each supplier offers different prices, so there may be price differences. There may be various reasons for this, such as higher purchase prices for smaller quantities or additional import costs.

The HDDs are only plugged into one slot. You do not need any additional cables for operation in a Synology NAS. Have fun with your new NAS!

Of course you can use the WD Red Pro in the DS224+. Only the Plus models have been tested and included in the compatibility list by Synology, but the Pro models work perfectly. A RAM expansion can never hurt, whether it makes sense depends on which services are running on the NAS and what the intended use is.

As the largest online shop in Switzerland, we naturally also have to sell the fastest hard drives! 🏎️💨 Joking aside, the maximum speed of the hard drive is of course 7200 RPM, as you mentioned. Thank you for pointing this out, I will inform the relevant department.
