Not all SSD are created alike. Some perform better than others.
I don't know anything about 'ADATA' but the biggest thing with SSD over SATA is not throughput but seek time / random read/write.
If you're just reading and writing large files sequentially SATA will work fine. If you're serving hundreds or thousands of requests per second and they're all small requests from all over the storage - SSD will win any day of the week hands down.
