AS6508T Too slow

[anna.tronci]

Hi to all, I just upgraded to AS6508T from 3304T (that I still own it) but doing download test i don`t see a very huge improvement.

Test done : folder about 49 gb

- AS3304T 120 > 150 mb per sec

-AS6508T 190 >370 mb per sec

- 10gigabit lan

- Switch Zyxell XS 1930-10

-Ironwolf 8tb single on AS 3304T

-x 4 ( SEAGATE HDD BARRACUDA 4TB 3,5 7200RPM SATA3 256MB CACHE ) 4TB raid 5 on AS 6508T + 2 NVME for cache ( SAMSUNG SSD 970 EVO PLUS M.2 PCIE 3.0X4 NVME 3.0x4 1TB r/W 3500/3300 MB/S ) + KINGSTON RAM SODIMM 8GB DDR4 2666MHZ CL19

Any expert advice or suggestion, i`m very disappointed about performance.

Thanks in advance

Anna
