Jason,

I am not sure, whether this running firmware (fr: 1P3QEXE7) was the latest one.
Moreover, this device is a newer one and we bought couple of months back.

When I am tried to update SSD firmware using Samsung Portable SSD Software, 
it failed to communicate with their Samsung servers.

Let @Pankaj Raghav <pankydev8@...il.com> can get back on this and confirm 
about this firmware version, as he reported this issue internally to Samsung. 

Regards,
Monish Kumar R

Isn't the latest firmware for the QEXE7 line 2B2QEXE7?
