What is this graph?
The graph below shows the read and write tests of drive performance with different system setup combinations in a 7600. For example: The stock 7600 scored a 6.66 sustained read and a 7.58 sustained write, while on the same computer with a G3/400MHz upgrade scored a higher 7.37 sustained read and a 8.56 sustained write.
Keep in mind the 4GB ATA Quanutm drive that was used in this test had a slower RPM speed and seek time than the 2GB SCSI Quantum. However, it scored noticeably higher than the stock 2GB SCSI Quantum in the same tests! Imagine a ATA drive that is comparable in features to the 2GB SCSI drive!
Installation is a snap!
Basically you take the UltraTek PCI card and install it into your PowerMac's open PCI slot. Take the ATA cable that came with the card and plug it into your new PCI card. Take your ATA drive, and plug the other end of the cable to it. Adjust the jumpers on your ATA drive, restart your computer, and format the HD if needed. You now have a fast ATA drive on your previously all SCSI PowerMac. No software or jumpers on the PCI card!
What is in the box?
VST's UltraTek ATA/66 comes with the VST UltraTek/66 card, a CD with SoftRAID Software (not used in this test) and documentation, two 80-wire/40pin ATA cables, a user manual, and a Power Supply "Y" Cable.
At first I was skeptical about this product with it being the cheapest ATA PCI card in our line up. Then things started to take a turn with the extremely easy set up. I literally plugged everything in and it worked flawlessy the first time. Granted you have your drive setup properly and it's formatted.
If your looking for more hard drive space and speed, this is the cheapest and easiest solution for you and your PowerMac. With the wide range of low cost, high capacity ATA hard drives available today, you have even more reason to take advantage of ATA. Those bars on top do not lie. Look at the read test results. The same computer with the same processor scored approximately twice as fast as the faster 2GB SCSI with the simple change of a ATA PCI card and a slower ATA drive! To add even more performance overall with your PowerMac, add a G3/G4 processor!! (shown in graph)
