Question about Delock Host Bus Adapter PCI-ex16v3

Question about Delock Host Bus Adapter PCI-ex16v3 - 5xM.2 Key-B, SATA

4 years ago

Are 5 SATA drives recognised? Do they share the 6 Gb/s in the five slots or do they each have 6 Gb/s? If bifurcation, then theoretically up to 30 Gb/s should be possible, is that right?

It is important to understand this product properly. (Unfortunately, nowhere is the back shown...then you would see the chip).
I have seen in the questions that it is basically unclear what the product can do. Therefore, here is the full explanation.

a)
Only SATA SSD's can be used, NOT NVMe PCIe SSD's.
b)
You can directly plug in M.2 SATA SSD's or also connect SATA SSD's in 2.5" format with the supplied M.2 adapters.
c)
Between the PCI-e x16 slot and the 5 SATA SSDs is this chip, which takes care of the multiplexing: JMicron JMB585.
The chip can do "2 lane PCIe to 5 SATA port".
So only PCIe x2 is used. Total transfer rate 2 GB/s = 16 Gb/s. Best case.

Quote: "Finally, the JMB585 is a new product that almost reaches PCIe Gen3x2 line bandwidth".

If you read the description in full, you will get this information: A combination of SATA devices and M.2 SSDs is also possible.
This probably means NVMe SSD. But then probably not with the optimal speed. For example, I have a SATA adapter on my MAC as a boot drive in which an NVMe SSD is running.
My question would be whether all the built-in SSDs are recognised in the MAC on the PCIe16 Delock adapter (RAID) or just the first one.

Your data. Your choice.
