Abstract: A data buffer adjustment method for a solid state drive is provided. The solid state drive includes a power supplying unit, a monitoring unit, a controlling unit, a cache unit and a storage unit. An accessing electrical energy from a first power source module or a second power source module is selectively supplied to the power supplying unit. In case of power interruption, the accessing electrical energy allows data to be written from the cache memory to the storage unit. The data buffer adjustment device includes the following steps. Firstly, the monitoring unit monitors a capacity for storing electricity of the second power source module. According to the capacity for storing electricity, a size of a temporary storage space of the cache unit is dynamically adjusted. According to the size of the temporary storage space, an amount of the data is determined.
