Design

The Asustor Flashstor 12 Pro FS6712X has a unique design, with a rhombus cross-section that adds visual interest to an otherwise plain enclosure.
It's a bit of a shame that the glossy black plastic used obscures the reliefs and shapes on the surface.
The underside of the unit provides access to the first six M.2 slots via four screws, and it's great that an 80mm fan is included and connected to the system with a repurposed USB-A plug and receptacle.
The drives are held in place with a plastic clip, making it easy to install them, although it's worth noting that only 2280-size modules are accepted.
You'll need to remove the lower panel to install more than six drives or upgrade the RAM, which requires three additional screws.
It's worth considering adding drives with heatsinks to dissipate heat better, as there's plenty of space above the M.2 slots.
Features
The Asustor Flashstor 12 Pro FS6712X is a powerful NAS that supports USB 3.2 Gen 2, which enables transfers to or from external SSDs at speeds of up to 1000MB/s.

The 10GbE port is a significant feature, but it's worth noting that it takes up one lane, leaving limited bandwidth for other components. The dual USB 3.2 Gen 2 ports take another lane, leaving six lanes for the M.2 slots.
Each of the M.2 slots gets a single PCIe 2.0 slot or half a PCIe 3.0 allocation of bandwidth, which might not be sufficient for performance NVMe drives. This could result in speeds of up to 2,000MB/s, but that's unlikely.
The network bottleneck is another issue, as the single 10GbE LAN port has a maximum speed of around 1200MB/s. This can easily be satisfied by a single NVMe drive, making performance-enhancing RAID layouts unnecessary.
