6. Disk Drive Performance Hacks > 61. Kick It Up a Notch with Serial ATA

Kick It Up a Notch with Serial ATA

Upgrading to Serial ATA will stomp all over UDMA-5’s 133 MBps performance.

Disk drives using the new Serial ATA (SATA) data interface could deliver data throughput performance enhancements 12%, 125%, and even 350% higher than today’s fastest UltraIDE-133 disk drives. We won’t see these phenomenal (+125-350%) improvements as long as SATA interfaces on the system board continue to use the lagging PCI bus, but some motherboards with built-in SATA interfaces provide an alternative bus for higher performance. You can get that extra 12% boost today with Serial ATA-150 adapters, like Promise Technologies’s SATA150 TX4 and SATA150 TX2Plus.

Tip

Newer chipsets, such as the Intel 865PE, provide a separate data bus dedicated to faster storage devices. (For example, the 865PE provides a 150 MBps bus for Serial ATA.)
