The need of (different) WWN on Sata SSDs seems quite new for some Vendors. I have had the same problem with a couple of SSDs (Winkom Pro) that I bought recently.
Winkom was very helpful to fix the problem with newer SSDs and i was able to send them back for SSD's that have a firmware with unique WWN.
