Although the Rock64 is noticeably slower than the Raspberry Pi, having hardware AES could be a significant advantage when securing things with TLS, IPSec and dmcrypt. Since the Rock64 is listed as having long-term supply until 2022, now is mid-life in the product cycle. At the same time, the boards I recently received appear not to meet the quality standards necessary for long-term use.
I'm wondering whether I was just exceedingly unlucky. Has anyone else had a Rock64 that experienced memory problems or suddenly started booting with less memory than physically present? How likely will the same thing happen again if I buy a replacement?
