/dev/urandom will be slow compared to doing something like arc4 in
userland - even if the kernel implementation is fast (which it may well
be), arc4 is cheap enough that just the syscall overhead of reading
from /dev/urandom will probably cost more cycles than doing arc4 in
userland.

Besides, for this even a multiplicative congruential RNG quite possibly
would be enough.  You don't need cryptographic strength; you just need
something random enough to defeat the SSD's compression algorithm(s).
