SSDs do not cooperate well with Swap.

On all computers that have Solid-State Hard Drives – aka SSDs – anything corresponding to a Linux Swap Partition, or to a Windows Swap File, will end up killing the SSDs eventually, because the rewriting of data to an SSD is capped by a finite limit. Thus, if we were to install Linux on such a device, we would probably want Swap to be Off.

But then this realization also poses the question, of whether Android Kernels have specifically been compiled with compiler-flags set to disable Virtual Memory. Linux Kernels traditionally have the option, of allowing their compilation with VM disabled. Since the ARM CPU is a RISC-chip, there is even some possibility that this CPU may not have a TLB.
