We found that the Aura Pro X2 was generally slower than current high-end M.2 NVMe SSDs, though it typically still outperforms entry-level NVMe drives. Putting the Aura Pro X2 in an adapter and testing it on our usual desktop testbed allowed us to dig into its power efficiency and explore its performance potential with fewer limitations from the host system, which may be more relevant to Mac Pro users than MacBook Pro users.

That's something that could not be said for OWC's earlier attempts to provide an upgrade in this form factor. The differences in benchmark scores aren't always large enough to have a dramatic impact on real-world use, but the Aura Pro X2 is definitely faster overall. In spite of these limitations, the Aura Pro X2 is consistently able to deliver better performance than the Apple original SSDs, especially for random IO.
Our macOS-based testing showed that the performance differences between modern NVMe drives are largely erased by bottlenecks elsewhere: filesystem overhead and the general inefficiency of performing asynchronous IO using kernel thread pools on low-power mobile CPUs with low core counts.

The older Macs that the Aura Pro X2 is designed for impose some performance limitations that modern machines don't experience, so in most real-world use cases the Aura Pro X2 isn't able to show off the full capabilities of its newer hardware. In principle, this allows for not only higher capacities at lower prices, but also better performance and power efficiency. The OWC Aura Pro X2 is based on much newer technology than the Apple original SSDs it is intended to replace.
