We are working on JMB585 :slight_smile:
Stay tunned :slight_smile:

#3

I got 2x of these @jack


Prob only ever use 2-3x ports on them though and use them as sata ‘splitters’ rather than loaded with 3-5 drives.
With 2-3 ports on the multiplier and the x4 port Marvell thats 8-12 disks with reasonable throughput.
