Samsung EVO 860 and/or 870 models do support SATA1, AFAICR, unless that has changed.

AFAIK Samsung is not SATA1 compatible, you can't set it to strict SATA1 mode via any utility, which is why VIA south bridge does not work with modern drives. But you can do that for many HGST HDDs and Sandforce SDDs.

One may not be able to explicitly set it to a forced SATA1 mode, but if it works on a SATA1 controller (other than a VIA one), I would still call it SATA1 backward compatible from a practical point of view, except for VIA SATA1 controllers. I guess it's down to semantics as to what "compatible" is implied to mean.

Are there other SATA1 controllers, beside VIA ones, that behave that way?

What do you think about the double bridge potential workaround that I mentioned ?

From what I've heard, some old nForce SATA also have issues.

Nforce2 with MCP2 S/R/GB south bridge - example Abit NF7-S2G, Nforce3- example Abit Nf8 pro - and nforce4-4X - example Abit AN8 - with SATA1 controller have serious problems with SSD's, including old intel SATA2 ones! However they are running just fine with Raptor 150gb. In fact all my socket 462 and 754 systems are running Raptor 74gb/150gb and are pretty snappy.

Then they will also work nicely with Sandforce SSD via SATA mode switch.
