- *SATALite interface allows for two additional SATA devices (4 total). It is required for RAID 0+1 on VT8237R Plus.
- The SATA-II feature of VT8237S is limited to 300 MB/S Data Transfer Rate bearing no NCQ functionality.
- Motherboards frequently had VIA companion chips for added functionality such as better audio (8 channel), more/faster USB (i.e. USB 2.0 for VT8233), or Gigabit Ethernet.
