which firmware do I use

[exekutive]

Which chipset do I have? The markings don't have 'A' or 'B', or the dump.
It's from a Unitek USB SSD enclosure.

I didn't find anything related to rtl9210 on the Realtek website.

This is the first revision, so the RTL9210(A), you can go to firmware 1.30.21.070622

Thank you muchly

Hmmm, I have I think the same model of that enclosure. I had updated it some time ago to 1.34.39. I don't remember while it was always RTL9210(B) in my case, or it is reported as such after update... I updated it using config created from the dump. Is it possible that I updated RTL9210(A) using firmware for RTL9210(B), and now it seems working and appears as RTL9210(B)?

Ok, I have dissembled it. It looks like this really is RTL9210(B). So they produced that enclosures with both versions of the chip. PCB seems the same or very simmialr.

@Szewcson what year did you purchase yours?
This one is a little bit unstable.

[Szewcson]

Bought that one in 2023. Seems stable. I was previously heve other one as work equipment and it was unstable until I updated the firmware (which back then was provided by Unitek on their website). Don't remember which version was that.

Based on the dump and the chip marking (which shows “Realtek RTL9210” and not “RTL9210B”)

Unfortunately, manufacturers often mix both revisions within the same enclosure model, which makes firmware selection quite tricky :/

[Szewcson]

As I eddited before it looks like mine is from the batch that in fact have RTL9210B - checked chip markings.

Looks like Unitek have stopped using Realtek chips in this enclosure. Their current one has a JMicron JMS583. When I was researching my original one, I remember the Realtek chips were considered the best. I will probably get Plugable or Sabrent this time.
