We had two 2013 Nexuses: one with 3g radio and one wifi-only.
First, the 3g one died, on sudden black screen of death. Then, year or two later, the wifi one, on the flash deterioration.
The flash issue wasn't problem only for Nexus. The Asus Transformer line had exactly the same problem (Nexus 7 was made by Asus).
The 3g one was replaced by Sony Xperia Z3 Tablet Compact. That thing still lives, albeit it is on Android 6 and the battery life is short. Too bad Sony doesn't make tablets any more.
