I have a DS220+, but i guess this question applies to the entire synology NAS line.

The DS220+ is advertised as being capable of 225 MB/s read and 192 MB/s write. Im wondering why this speed is even advertised, given different drives have different speeds.

My only guess is that this is the max speed you can get when using link aggregation of the 2 ethernet ports, but if thats the case, Im not too sure why they advertise a different read and write speed as opposed to one maximum transfer speed.

For context: i currently get about 200mb/s read/write from one drive, but am considering switch to a 2 drive raid0 config to double that speed (i know raid0 has a bad rep but if something goes wrong this data can easily be redownloaded. Speed is far more important than data integrity for this setup). im currently not using the ethernet ports at all and am instead using it’s usb 3.0 port and a 5g ethernet adapter (which has worked quite well). My wired network is capable of 10g speeds, I dont anticipate any bottlenecks on that side of things. Given my setup, would the advertised nas speed of 225mb/s read and 192mb/s write apply to me? Is there some internal bottleneck with the nas itself beyond its ports that I havent considered?

Thanks
