Question about 2.5GbE networking

[TallSeaBird]

If I have a 1GbE router which cascades down to a 1GbE switch and I cascade down to a new 2.5GbE switch - will the devices connected to the 2.5GbE switch operate at 2.5Gb speeds? Do all 'routes' have to go through the router? (When I talk about 1GbE and 2.5GbE I know these are theoretical maximums)

Thanks, that's my question answered. I have a NAS with 2 2.5GbE NIC's and a mini PC with 2 2.5GbE NIC's and I might investigate getting a 2.5GbE to USB adaptor for my Synology NAS.

The top of the tree is a 1GbE router which initially cascades down to a 1GbE switch - the 2.5GbE devices all sit below that
