Would a 240 MB/s DRAM-less SSD in a PS4 be faster than og 100 MB/s HDD?

I bought a SSD for my ps4. I know that when transferring or downloading large files that I can slow down a lot. I got a SSD that locks to about 240 MB/s since my system is SATA II. I play a lot of open world games. Will the game loading in assets from my SSD slow down the speeds. I know that 240 MB/s is obviously faster than 100 MB/s but can the lack of DRAM make it lower than 100 MB/s?
