By following the guide above (32KB FAT32 + alignment + defrag), you will turn the PS2's weakest link into a surprisingly capable loader. You won’t get SATA SSD speeds, but you will finally eliminate the "disc read error" message forever.
Here is the definitive process to achieve the legendary "Extreme" speed. usb extreme format ps2
ul.cfg : A small configuration file (the "Table of Contents" for your games). ul. [Game ID].00 : The first 1GB chunk of the game. ul. [Game ID].01 : The second chunk (and so on). ⚠️ Known Limitations

For comparison, a CD-ROM runs at 1,500 KB/s, while the PS2 USB runs at roughly 1,500 bytes per second in real-world scenarios. If you plug in a standard NTFS or FAT32 drive with FMBC (Free Memory Card Boot), games will stutter during cutscenes and lag on loading screens.
