Manage to find Fujitsu laptop but with normal hardisk. but no screenshot
Thinkpad: Write-110MB/s Read-108MB/s
Fujitsu: Write-44MB/s Read-38MB/s
while Thinkpad finish the write and start to read, Fujitsu still writing lol
there is no performance drop on thinkpad, and if you combine both write, it should hit write speed of 160MB/s but thats still limited by Fujitsu hardisk read speed not the NAS speed or Link Aggregation speed.
conclusion:
link aggregation do improve the performance if you have more than 1 PCs/Laptops or your PC got link aggregation/teaming function.
