I decided to test this hack thoroughly on my rig. Here are my results using CrystalDiskMark (Settings: NVMe Profile, 5 Passes, 4GiB size to properly stress the cache).
My Setup:
Drive: WD_BLACK SN850X 2000GB (NVMe Gen4).
Condition: Firmware updated to the latest version (620361WD.
The Results: I compared the "Server 2025 Driver" (Hack) against the Stock Windows Driver.
Contrary to the article, the hack provided zero benefit to Sequential speeds on my drive. However, the hack severely impacted Random 4K performance (latency and daily responsiveness).
Metric Registry Hack (Server Driver) Stock Driver
Seq Read (Q8T1) 7,365 MB/s 7,365 MB/s
Identical
Seq Write (Q8T1) 6,614 MB/s 6,595 MB/s
Identical
RND 4K Read (Q1T1) 65.77 MB/s 74.68 MB/s
Hack is -12% Slower
RND 4K Write (Q1T1) 159.36 MB/s 250.84 MB/s
Hack is -36% Slower
Conclusion: For a high-end consumer drive like the SN850X, this hack degrades performance where it matters most (Random 4K). The "Server" driver seems to prioritize queue management in a way that hurts low-latency consumer tasks. I strongly recommend sticking with the stock driver.
