I can help with SSD model you need however we are still working on a upgrade guide as we currently only sell these units optionally pre-installed SSD. If you plan on purchasing an SSD make sure it's NGFF M.2 2242 model.
Will do. Thank you.
There are two SATA compatible m.2 slots on the 3100 with the stand-offs at different lengths. It will boot from either. They are at 42mm and 80mm so 2242 or 2280 m.2 modules.
The 42mm slot also carries the SIM card connections and USB for a 3G/4G modem so if you are considering ever fitting one you are better to use the 80mm slot for SATA.
I recently bought an SG-3100.
After having updated it with an SSD I like to share a little 'How To' with interested people.
Mount the SSD onto the board as shown on the attached picture.
Check if the SSD was detected at boot time:
[2.4.2-RELEASE][root@MP-SG-3100.localdomain]/root: dmesg | grep ada0 ada0 at ahcich1 bus 0 scbus1 target 0 lun 0 ada0: <nt-128 1.00=""> ACS-4 ATA SATA 3.x device ada0: Serial Number 977120660172 ada0: 600.000MB/s transfers (SATA 3.x, UDMA6, PIO 8192bytes) ada0: Command Queueing enabled ada0: 122104MB (250069680 512 byte sectors)</nt-128>
Create the partition table:
[2.4.2-RELEASE][root@MP-SG-3100.localdomain]/root: gpart create -s gpt ada0 ada0 created
Create two partitions:
A swap partition of 4GB
A ufs partition of 64GB

Check if the partitions are recognised by the OS:
[2.4.2-RELEASE][[email]root@MP-SG-3100.localdomain]/root: ls -l /dev/diskid/ total 0 crw-r----- 1 root operator 0x56 Jan 10 18:22 DISK-977120660172 crw-r----- 1 root operator 0x59 Jan 10 18:22 DISK-977120660172p1 crw-r----- 1 root operator 0x5a Jan 10 18:22 DISK-977120660172p2 crw-r----- 1 root operator 0x41 Jan 10 18:22 DISK-A41EE459 crw-r----- 1 root operator 0x44 Jan 10 18:22 DISK-A41EE459s1 crw-r----- 1 root operator 0x45 Jan 10 18:22 DISK-A41EE459s2 crw-r----- 1 root operator 0x49 Jan 10 18:22 DISK-A41EE459s2a [2.4.2-RELEASE][[email]root@MP-SG-3100.localdomain]/root: ls /dev/gpt gpswap gptmpfs
Formatting the /tmp/cache partition:
[2.4.2-RELEASE][root@MP-SG-3100.localdomain]/root: newfs -U /dev/gpt/gptmpfs /dev/gpt/gptmpfs: 65536.0MB (134217728 sectors) block size 32768, fragment size 4096 using 105 cylinder groups of 626.09MB, 20035 blks, 80256 inodes. with soft updates super-block backups (for fsck_ffs -b #) at: 192, 1282432, 2564672, 3846912, 5129152, 6411392, 7693632, 8975872, 10258112, 11540352, 12822592, 14104832, 15387072, 16669312, 17951552, 19233792, 20516032, 21798272, 23080512, 24362752, 25644992, 26927232, 28209472, 29491712, 30773952, 32056192, 33338432, 34620672, 35902912, 37185152, 38467392, 39749632, 41031872, 42314112, 43596352, 44878592, 46160832, 47443072, 48725312, 50007552, 51289792, 52572032, 53854272, 55136512, 56418752, 57700992, 58983232, 60265472, 61547712, 62829952, 64112192, 65394432, 66676672, 67958912, 69241152, 70523392, 71805632, 73087872, 74370112, 75652352, 76934592, 78216832, 79499072, 80781312, 82063552, 83345792, 84628032, 85910272, 87192512, 88474752, 89756992, 91039232, 92321472, 93603712, 94885952, 96168192, 97450432, 98732672, 100014912, 101297152, 102579392, 103861632, 105143872, 106426112, 107708352, 108990592, 110272832, 111555072, 112837312, 114119552, 115401792, 116684032, 117966272, 119248512, 120530752, 121812992, 123095232, 124377472, 125659712, 126941952, 128224192, 129506432, 130788672, 132070912, 133353152
The swap partition does not need formatting.
Add the entries for the new partitions to /etc/fstab:
# Device Mountpoint FStype Options Dump Pass# /dev/diskid/DISK-977120660172p1 none swap sw 0 0 /dev/diskid/DISK-A41EE459s1 /boot/u-boot msdosfs rw,noatime 1 1 /dev/diskid/DISK-A41EE459s2a / ufs rw,noatime 1 1 /dev/diskid/DISK-977120660172p2 /tmp/cache ufs rw,noatime 2 2
Create the mount directory:
[2.4.2-RELEASE][root@MP-SG-3100.localdomain]/etc: mkdir /tmp/cache [2.4.2-RELEASE][root@MP-SG-3100.localdomain]/etc: mount /tmp/cache [2.4.2-RELEASE][root@MP-SG-3100.localdomain]/etc: df Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/diskid/DISK-A41EE459s2a 7351996 817852 5945988 12% / devfs 1 1 0 100% /dev /dev/diskid/DISK-A41EE459s1 34442 2002 32440 6% /boot/u-boot /dev/md0 3484 132 3076 4% /var/run devfs 1 1 0 100% /var/dhcpd/dev /dev/diskid/DISK-977120660172p2 64995324 8 59795692 0% /tmp/cache
The swap partition can be manually activated but a reboot will do it automatically and test the system at the same time.
After all is done the swap and the /tmp/cache partition will be displayed on the dashboard of the web interface.
I would just backup, recover to ada0, restore, and forget the on-board storage exists.
That way you don't have to worry about upgrades, etc blowing up.
Thanks for the info.
Nice right up. :)
However I would definitely recommend installing directly to the SSD rather than trying to run across two disks.
The fstab may be overwritten at update and you can't be sure how things might behave if/when that happens.

There is now a write-up in the SG-3100 manual: https://docs.netgate.com/pfsense/en/latest/solutions/sg-3100/m-2-sata-installation.html
@derelict How can you directly restore to the new SSD? Do you need to reinstall the firmware or is there a process to copy and reinstall from the CLI / configurator?
I looked at the manual and didn't see anything other than inserting the new SSD.
@s0m3f00l Backup the configuration, reinstall to the SSD, Restore the backed-up configuration.
@derelict Awesome. Thank you. I can get the newest firmware via ticket correct? I have an older version on USB.
@derelict Last question, How do I remove the old install? should I just mount the internal storage and "rm -rf /"? Where is the bootloader located?

"rm -rf /"
Ah, the last century's 'DOS' method of upgrading.
What about a : insert the USB key containing the new 'ISO', and do a software reboot from pfSense using the wired console access using the other (micro ?) USB port.
If there is a key to enter in what might be some sort of BIOS or early 'device' boot menu, use that now.
See the complete 3100 manual for all the details.
Use the boot menu - as a classic PC - to boot from the USB stick.
If all goes well, the installer will take tell you or propose to use or import the already existing pfSense config.
Let it finish installing, it will reboot. Remove the USB as soon as it reboots.
Admire the works.
Btw : I do not have or own a SG-3100, and worse, I'm writing this right out of my head, a it seesm to be the logic way.
Be warned : I didn't consult the manual.
@gertjan I know how to upgrade I was asking about removing the old install from the old internal emmc drive, thanks though.
For anyone else reading this, I got in touch with netgate TAC and they recommended leaving the old install in place as a backup to the new drive. I assume the bootloader for the sg3100 is somewhere on that internal drive so don't delete.
You could erase the eMMC but there is little point doing so.
uboot is stored separately on an SPI chip.
