Add SSD to RN528X
Hi Following on from https://community.netgear.com/t5/New-ReadyNAS-Users-General/Add-SSD-drive-s-to-RN528X/td-p/1776859 I've just had a go at adding an M2 SSD to my new 528X. It seems have wo...
Thank you for the nice photos of the RN528X motherboard!
I see now how it differs from the 6-bay RN526X - the PCI-style connectors for the HDD backplane are longer, allowing for more SATA lanes.
I'm still curious though, what controller is used for the 2 extra disks? The D-1508 has only 6 built-in SATA channels. And the extra Marvel 88SE9170 chip on the motherboard (at least that's what my RN526X has) provides only 2 extra SATA channels - one for the M.2 and one for the eSATA connector on the back.
Is it possible that the 8-disk RN528X has a different Marvel chip? Can you post the output of
lspci|grep SATA
Also, it might be instructive to see the output of `lsscsi`. Here's for example mine, with 5 bays occupied with 4TB WDs, an M.2 SSD in the slot on the back, and an external Seagate USB-enclosure:

Hmmm... This is interesting - from your lsscsi output one might conclude that you have 7 disks connected to the 6-channel SATA controller that's built into the D-1508 CPU. Which - if true - implies the presense of a SATA switch (on the HDD backplane?).
Maybe if you also post the output of 'ls -al /sys/block/sd*' ?
Here's my output for reference:root@RN526X:/data/tmp# ls -al /sys/block/sd* lrwxrwxrwx 1 root root 0 Jan 13 02:05 /sys/block/sda -> ../devices/pci0000:00/0000:00:1f.2/ata1/host0/target0:0:0/0:0:0:0/block/sda lrwxrwxrwx 1 root root 0 Jan 13 02:05 /sys/block/sdb -> ../devices/pci0000:00/0000:00:1f.2/ata2/host1/target1:0:0/1:0:0:0/block/sdb lrwxrwxrwx 1 root root 0 Jan 13 02:05 /sys/block/sdc -> ../devices/pci0000:00/0000:00:1f.2/ata3/host2/target2:0:0/2:0:0:0/block/sdc lrwxrwxrwx 1 root root 0 Jan 13 02:05 /sys/block/sdd -> ../devices/pci0000:00/0000:00:1f.2/ata4/host3/target3:0:0/3:0:0:0/block/sdd lrwxrwxrwx 1 root root 0 Jan 13 02:07 /sys/block/sde -> ../devices/pci0000:00/0000:00:1f.2/ata5/host4/target4:0:0/4:0:0:0/block/sde lrwxrwxrwx 1 root root 0 Jan 13 02:07 /sys/block/sdf -> ../devices/pci0000:00/0000:00:1c.0/0000:05:00.0/ata11/host10/target10:0:0/10:0:0:0/block/sdf lrwxrwxrwx 1 root root 0 Jan 31 14:18 /sys/block/sdg -> ../devices/pci0000:00/0000:00:14.0/usb3/3-2/3-2.1/3-2.1:1.0/host13/target13:0:0/13:0:0:0/block/sdg
