Google présentera toutes les nouveautés le 3 juin 2020
à priori pas de boot par usb mais à voir
(sinon + de 800mo/s ! )

vraiment pas mal
support jusqu'à 4 disque en RAID 0/1/5
branché sur les ports USB 3.0 les perfs devraient être acceptable.
et ils ont même prévu un boitier

pas donné mais je vais acheter ce boitier fanless, vraiment efficace

pas mal 2ghz !
au lieu de 1.5ghz

we used the aluminum housing of the case to provide a built in heat sink. Supplied with the case is a thermal pad
Idle – 62°C
Phoronix benchmarks download/installation – 64°C
John The Ripper – 73°C
I also typed a few commands to get the system temperature and CPU clock, in this case during John the Ripper benchmark:
temp=85.0'C
So the CPU is clocked down to around 1.0 GHz since proper cooling is not implemented for this type of workload, and the system automatically lowers the CPU frequency.
pas plus perf que le pi3 si pas bien refroidit ... (en bench en tout cas)
