Some clarifications: Minimum SSD write is much less than the erase block. Erase block is the minimum block size that can be erased. For SSDS, there are 2 key concepts: 1. Read granularity < write granularity < erase granularity 2. Cells that have been written to must be erased before writing again. Most SSD vendors will buffer write contents to collect a `write granularity` worth of data to avoid wasting bytes writing padding. This can be hard to do on drives without capacitors to supply backup power in the event of power loss.
