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 worked!!
I purchased a TS120GMTS420S from Amazon (£28.46). Installed it in the M2 slot on the back of the motherboard (convenient cut out although I had taken the MB out to add 16GB RAM as well). See pictures at end.
SSHing in you can see it's recognised as sdb. I currently only have 1 2TB scratch disk in for testing.
root@MediaMaster:~# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 1.8T 0 disk ├─sda1 8:1 0 4G 0 part │ └─md0 9:0 0 4G 0 raid1 / ├─sda2 8:2 0 512M 0 part │ └─md1 9:1 0 511.4M 0 raid1 [SWAP] └─sda3 8:3 0 1.8T 0 part └─md127 9:127 0 1.8T 0 raid1 /data sdb 8:16 0 111.8G 0 disk
So I then did the following. Please note I am in no way a linux expert and there is some guesswork here.... if I've done something wrong please tell me!! It does seem to work though!!
I hope this is helpful. Always grateful for feedback.
Andy

I guess one question I have would be:
Ideally an SSD should be partitioned on 2048 sector boundry and this was the sgdisk default. I overrode it to 64 sectors to mirror the original partitions exactly. Is this necessary?? Or as long as they are the same size in sectors does thte starting sector matter??
When creating volumes on a drive that the GUI cannot see, it is best to use the Netgear utility volume_util (aka rnutil volume_util), not do everything manually. volume_util --help will point you in the right direction. Once the volume is created, the GUI should see it, and everything else can be done from there.
Note that this is for devices the GUI is not designed to see, such as the M2 SSD here or a drive in a non-Netgear external SAS chassis (on compatible rack mount systems), not for a drive that simply fails to show up when it should.
Thanks.
I'll factory reset, clear the SSD and have a play.
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
