I found that my Odroid XU4 was /almost/ fast enough to be my daily
driver. But the fan would kick in for some things and I didn't care
for the noise of the stock fan. I've not yet compared contemporary
Raspberry Pi 4 or other comparable systems.
Samsung Exynos 5422 is developed on the 28 nm technology node and
architecture Cortex-A15 / Cortex-A7. Its base clock speed is 1.40 GHz,
and maximum clock speed in turbo boost - 2.10 GHz. Samsung Exynos 5422
contains 8 processing cores.
Instruction set (ISA) ARMv7-A32 (32 bit)

Yes, its an xu4 and as I mentioned, its a USB drive (seagate 4G backup
with an SMR inside) - works ok as a backup drive and the data transfer
is fast until you fill the cache - then its throughput is best
described as "miserable"! The xu4 lists as 32bit and odroid supplies
a 32 bit kernel etc - I just used their config as a base when building
gentoo onto it - its my build (for 5 xu4 based HC2 systems) and hosts
the backup drive. My attaching the hdparm run was an example of its
use, and that happened to be the terminal i was using at the time.
