This is a follow-up to my previous BE7200 issue with external HDD instability:
👉 https://community.tp-link.com/us/home/forum/topic/715550

TP-Link support gave me a special firmware at that time:
**be450v1-up-jp-ver1-0-2-P1[20250114-rel54256]_2048_nosign**  
It fixed the HDD issues completely — stable speeds and no more crashes.

Now I’m using a **WD SN580 NVMe SSD (2TB)** in a USB enclosure (JMS583 / RTL9210).  
After re-flashing that same firmware, the SSD can now be recognized.

But the problem is:
- File browsing (via SMB) is **very slow**
- Copy speed is **extremely unstable**, mostly stuck at **0MB/s**

I also tried the **latest public firmware**, but it made things worse — even HDDs became unstable again.

Just to confirm:

✔️ The same SSD works perfectly on my **Archer C2300**, stable high speed  
❌ Only BE7200 shows this strange behavior

System info:
- Windows 11
- NTFS / GPT format
- SMB access over WIFI 6E

Has anyone else tried NVMe SSDs with the BE7200?  
Would love to hear if there’s a way to improve stability — or if TP-Link plans to improve SSD compatibility in firmware updates.

Thanks!
