The 2GB RAM quad cores usually take about 20 seconds to boot from flash.
with performance similar to PCs for many desktop applications.
There is no SATA but USB can be used with SATA drives
if needed. Also possible to if you are designing your own board,
then use eMMC - They are low cost and the more
recent eMMC modules have performance similar to SSDs.
