Hard Drive ATA100 vs. ATA133

Introduction

Although ATA133 is hot topic when it comes to motherboards, it's a shame that the hard disk drive market hasn't kept up since almost every new board now supports the ATA133 or the Ultra DMA Mode 6 standard, but there are only a handful of drives that are actually compatible. ATA133 suggests that a capable hard drive can theoretically push 133MB/s in burst mode, much like how memory bandwidth is talked about. This figure is somewhat artificial, and real-world performance is what counts in the end, which is precisely what the following pages are about. We go over a brief but direct comparison between ATA100 and ATA133 (Ultra DMA modes 5 and 6) with one of the original ATA133 drives - the Maxtor D740X-6L.

Testing

The motherboard of choice is the Soyo KT333 Dragon Ultra, which offers support for both ATA133 IDE and RAID. Unfortunately we won't be testing the RAID performance today, but we will be taking a close look at synthetic as well as content creation benchmarks. Using the VIA 3.14 IDE Miniport Driver, it makes it easy to switch between mode 5 and mode 6 DMA, while the driver itself is proven to be one of the fastest and most reliable IDE drivers for the VIA platform. That's it from me now, i'll let the pictures do the talking from herein.
 

Test System:

Processor: - AMD XP1600+ (1.4GHz)
Motherboard: - SOYO KT333 Dragon Ultra
Memory: - Apacer 2x256MB PC2700 DDR333 DIMM
Storage: - Maxtor 20GB ATA133 7200RPM
Graphics: - Abit Siluro Geforce4 Ti4400
Sound: - Onboard Sound
Power: - Enermax EG365-VE(FMA) Dual Fan PSU
Case Info: - Steel, No additional fans
Software: - Windows XP Professional
- VIA 4.38 4-in-1 Driver Set
- VIA 3.14 IDE Miniport Driver
- SiSoft Sandra 2002
- MadOnion PCMark 2002
- HD Tach 2.61
- WinBench 99

Conclusion
 

The results may vary between drives, but the difference in performance from ATA100 and ATA133 is negligible. In some instances the results were very close, while in others like the High-End Winmark tests mode 6 DMA took the lead. I was also quite surprised to see that ATA133 was actually beaten in the HD Tach tests when in ATA100 mode. ATA133 should theoretically be 33% faster than ATA100, but my results basically didn't show much of an improvement at all. If you're thinking about upgrading a single drive from ATA100 to ATA133, I say keep you cash and wait for something better - there's always SCSI too! Keep that main idea behind ATA133 is minimise bottlenecks in the system when your running MORE than one drive, and to allow manufacturers to build drives larger than 120GB.
