For storage-heavy logging, the Auvidea carrier board with the most M.2 slots is the JNX410. It has 13 M.2 slots: twelve M-key 2280 slots plus one M-key 2242. JNX410 key points - Its 12 M.2 key M slots run through a 13-port PCIe switch. The board also has GbE, HDMI and CAN/RS485. - It works with Jetson Nano, Orin NX, Orin Nano and TX2 modules. auvidea.euauvidea.eu ↗“Jetson Nano, Jetson Orin NX, Jetson Orin Nano, Jetson TX2” auvidea.euauvidea.eu ↗“twelve M.2 key M slots via a 13-port PCIe switch, GbE, HDMI, CAN/RS485” auvidea.euauvidea.eu ↗“io.m2_slot_count=13”
- It needs 24V input at 100–200W and measures 240 x 104.6 mm. auvidea.eu +1auvidea.eu ↗“Power requirements 24V (100-200W)”auvidea.eu ↗“240x104.6mm”
- I couldn't find which slot the M-key 2242 is meant for.

| Board | M.2 slots | Slot types | Supported Jetson modules |
|---|---|---|---|
| JNX410 | 13 | 12x M-key 2280, 1x M-key 2242 | Nano, Orin NX, Orin Nano, TX2 |
| JNX46 | 5 | B-key 3042/3052, E-key 2230, E-key 2242, 2x M-key 2280 | Xavier NX, Orin Nano, Orin NX |
| JNX45 | 4 | B-key 3042/3052, E-key 2230, 2x M-key 2280 | Xavier NX, Orin Nano, Orin NX, Nano, TX2 NX |
| JNX400 | 4 | 4x M-key 2260/2280 | Nano, TX2 NX, Xavier NX, Orin NX |
The JNX400 isn't a single-module storage board. It holds four Jetson modules and gives each module its own M.2 NVMe slot. On the JNX46 and JNX45, only the two M-key 2280 slots are usual SSD slots. The other slots are B-key and E-key. auvidea.euauvidea.eu ↗“one M.2 NVMe slot per module”
A few Auvidea boards don't have an M.2 slot count listed, so I couldn't include them in this comparison: JNX30M, JNX42, JNX82, JNX84-LC and X221D.
