SAS backplane or cable assembly SFF8087 to 4 SAS/SATA. What is the difference?

Question

RAID

Good time. Question to experts in servers and server iron.

There is a computer in a small form factor self-assembly case and a RAID controller with an SFF8087 connector.
There is a task to place 4 2.5" drives in the case and connect them to the RAID controller.
I googled that this requires approximately the following cable assembly (SFF-8087 to 4x SATA). Plus, each drive needs to be powered additionally

. the server equipment market has so-called backplanes, to which you can connect drives through connectors and there is one connector for power. Something like this:
top view , bottom view . Or this backplane: top view , bottom view.

I think it is more aesthetically pleasing to use such boards for connecting drives. But the presence of some logic on these boards (chips, condos, etc.) is confusing.

Question:
How are these boards different from simple SFF8087 to 4xSATA cables ?
Will I be able to connect drives to a RAID controller using a backplane?
Or maybe there is some "tie" to connect only to native equipment?

Answer 1

Cable - for ANY four SATA, no matter how located and how powered.
Backplane - (pictured) for four sata / sas 2.5 "and for good it needs a native basket to fix everything normally, well, often the power connector is not a standard molex, but a proprietary one.
Loose on the backplane is the distribution of power and an indication of disk operation
