Hello,

Thanks for the great content. I’ve noticed that when it comes to Thunderbolt DAS solutions, there’s often no mention of whether the device actually uses PCIe tunneling or if it’s just relying on UASP like a regular USB device. This may seem like a small technical detail, but it makes or breaks a TB NAS.

Proper TB solutions do typically use PCIe tunneling, which allows them to attach a full SATA controller (via a PCIe-to-SATA bridge) directly to the host system. This allows the OS to see the SATA devices as if they were attached to an internal PCIe SATA controller... and this means full AHCI, RAID and SMART support, no USB-like abstraction or limitations, the OS uses the exact same driver stack as an internal PCIe SATA controller for maximum performance and reliability.

Including this in your reviews would add a lot of value and help clarify things for users trying to compare and decide on products.

This is indeed a critical technical detail that significantly impacts performance, functionality, and the overall user experience, especially for users expecting true DAS capabilities akin to internal storage.
