SATA drives shown as 'adX'

[saveZFS]

Hallo,
I'm running Truenas on an VM with ESXi 7u2 and a SAS3008 HBA (Passthrough).
I have 6x WD Red 4GB an 2x Seagate 1TB on my SAS3008 HBA (IT-Mode FW: 16.00.00.00).
I'm wondering, that my drives are shown as 'adX'.
Should SATA drives not shown as 'adaX'?

Isn't that 'daX'?
Chipset -> ada
HBA -> da

 

[saveZFS]

HBA -> da

Thank you very much.
I was strongly insecure, because I also couldn't watch my smart values by 'smartctl -a /dev/adX', because the system always wants that I specify the device type with '-d'.
So I though, that my drives are running in the wrong mode, but now I understand it. :)

The HBA is a combined SAS/SATA one so the device names in FreeBSD follow the SCSI "tradition".
