Hi ASRock community,

I?™m planning a high-performance workstation build around a PCIe 5.0 SSD (7.68TB, U.2 2.5") https://serverorbit.com/solid-state-drives-ssd/pci-e5-0-ssd/7-68tb-ri-2-5inch" rel="nofollow - https://serverorbit.com/solid-state-drives-ssd/pci-e5-0-ssd/7-68tb-ri-2-5inch and need advice on motherboard compatibility. Key requirements:

PCIe 5.0 Lane Allocation:

Does the ASRock X670E Taichi fully support Gen5 x4 speeds on U.2 via M.2 adapter?

Concerned about shared bandwidth with GPU (planning RTX 4090 in top x16 slot).

Cooling Solutions:

Will the SSD?™s sustained 12,000+ MB/s writes throttle without active cooling?

Any experience with ASRock?™s included M.2 heatsinks for U.2 adapters?

Real-World Use Case:

Primary workload: 8K video editing (DaVinci Resolve) + RAID-0 scratch disk.

Secondary: Game library storage (to avoid frequent reinstalls).

Current shortlist:

X670E Taichi

Z790 Riptide (if Intel better handles Gen5 splits)

Budget: ~$400 for the board. Thanks for any insights!
