The SSD won't directly care about that, but the more write commands with 
less than 4k the more data is effectively written to the device.

BTW: FAT16 with 0,5k block size is not that common since it is 
restricted to 32 MB. At 256 MB the cluster size is 4kB.
However, with FAT16 extra care needs to be taken to ensure the 
alignment, because the first cluster of a FAT16 volume does usually 
start at an odd sector number. It is possible to come around this by 
using the special reserved sector field of the boot block.
