MSA1050 SAS and e208e-p seems slow

[nikybiasion]

Hi, i've build a server with proxmox 7, hp DL360 Gen10 with e208e-p controller and i've connected to a san MSA1050 with mini sas cables. The san has a radi 10 with 6 sas 10k hdd
But the performace seems very slow...
One controller path write at 55MB/s and the other write at only 8MB/s
Anyone have experience with a similar build?
