advise for buying switches and creation SFP trunk

thank you for correcting me and pointing me to the given discussion. The NAS (Synology DS1817+) has 4 Gbit ethernet connections and supports link aggregation (LACP). I think of connecting them via an 4 port SFP trunk to the switch for optimal performance. But for an electrical galvanic separation between the two switches I need a fiber connection. Is the Netgear S3300-28X (GS728TX) - ProSAFE S3300 Smart Switch Series possible? I think of an uplink with 2 fibers: - 1 fiber connected in upload ports 27F from switch 1 (Netgear S3300-28X (GS728TX)) to switch 2 (Netgear S3300-28X (GS728TX)) port 27F and - one fiber port 28F on switch 1 connected to Switch 2 on port 28F Will it be possible to create a LAG between the two switches? ( the term link aggregation applies to various methods of combining (aggregating) multiple network connections in parallel in order to increase throughput beyond what a single connection could sustain, and to provide redundancy in case one of the links should fail. A Link Aggregation Group (LAG) combines a number of physical ports together to make a single high-bandwidth data path, so as to implement the traffic load sharing among the member ports in the group and to enhance the connection reliability. source: https://en.wikipedia.org/wiki/Link_aggregate_group)
