In my experience higher quality SD cards have been reliable for write-only purposes.
I have all of my DSLR camera SD cards and a couple of microSD's that get shelved when full and a new one is inserted. I also backup the data on them periodically to a 14 TB hard drive (in addition to storing/editing them in LrC and some also in Photos on my Mac).
Using SD cards for read, write plus, delete and os/application logging leads to fragmentation and definitely problematic in terms of reliability.
This is why all of my Raspberry Pi's have externally attached drives.
