I would advise against buying a Synology NAS solution with j in the name, the products are not well equipped. If possible I would also choose only a 4 drive NAS, they are a bit more expensive but you can work with more than 2 hard drives, e.g. buy three smaller ones and a fourth if you need more space. With 3 hard drives you also have extended hardware failure protection with RAID5 and you don't give away half the storage space as with a two drive NAS with RAID1.

My recommendation if it absolutely has to have two drives would be this NAS (4 core processor, 1 GB RAM):

Synology DS218play

But as I said, I would take one with 4 drives, which are also better equipped (more RAM, better processors), e.g. one with a 4 core CPU but even with 2GB RAM:

Synology DS418

The power supply unit is specified with 60W. This does not mean that the device requires that much.
