Loading times in Crimson Desert are brutal on my Soyo H510M, do I really need to switch to NVMe?

Seeing the loading bar fly by and scenes pop open instantly was such a rush. I had the game on an old SATA SSD, and the Soyo SY-King Dragon's SATA 3 port was hitting a massive IO bottleneck, with loads taking 40 seconds. I tried running a defrag tool, which only saved 3 seconds—a total waste of my life. I finally migrated the game to an M.2 NVMe drive, locked the port to Gen 3 in the BIOS, and updated the chipset drivers. Loading times plummeted from 40 seconds to just 10 seconds. I did hit a snag during migration with a partition table error that wouldn't boot, but reformatting to GPT fixed it. SSD temps are a cool 40-48℃. I switched the storage mode to 'High Performance' in the board utility, and VRM temps are sitting at 50-56℃. It's a whole different game now.
