this is nice for you

but keep in mind that for professional environments for many
years SSD is no option for some TB of data and even if
the price falls down you have to calculate redundancy for
RAID10 environemnts which can not be raplced by a SSD
due lack of relieability and no real-world expierience
how long they run and how you detect errors before it is
too late

SD cards as example are way less relieable than any rotating
media because for rotating media you get errors, a SD card
happily confirms write-operations for hours and does not
change the data on the meda, seen recently that after
overwirte with /dev/zero and format with any known FS
after pull out and plugin again the same data as two
wekks ago was on the card without any single warning or
error message besides a bricked phone by overheat
