| I grilled my local hardware security friend who said you should never trust
| the secure delete feature in ssd . In general it has been found insecure.

It seems hard to accidentally screw up Secure Delete:

- everything written to the flash layer is encode
- everything read from the flash layer is decoded
- secure erase simply changes the key

It is fairly easy to intentionally screw up Secure Delete.
Trusting Secure Delete involves trusting the manufacturer:
there is no sure way to test for this failing.

Does your guy have examples or even indications of Secure Delete failing?
In particular, what does "In general it has been found insecure." mean? 
What has been found?  How has it been found?
