Replace SSD on DEC750

[4dsf34w5]

What M.2 SSD key and sizes are supported for the DEC750 (official from Deciso)? I wasn't able to find more details in the brochure on key types or within these forums.

There is a teardown photo on here: https://wiki.junicast.de/en/junicast/review/opnsense_dec740

Its a 740 (same hardware though) and see the existing SSD model number from the photo and work out specs from that?

Thanks @Splodge for the helpful resource, looks like a ts128gmte110s which is a 2280 with an M key. I haven't attempted to replace it but leaving this info here regardless.

In my specimen, it was a TSMC part that did not hold up too well (i.e. wear was already at 35% after 1 year).
You can find out with "smartctl -a /dev/nvme0".

Be sure to get a "pro" level device, the speed does not matter all that much (PCIe 3.0x4), but wear resistance does: more unused storage = good. I used an M.2 USB enclosure to clone the internal device first, then replaced it and then grew the ZFS partition, but you can also install from scratch and restore your config.
