Serial ATA RAID Controllers - Promise, Silicon Image, Highpoint and nVidia

HD Tach 3.00 BETA


HD Tach has been around for a long time and is excellent when it comes to testing hard drive performance. It is also a very handy program when it comes to testing the controller used on particular motherboards. Tests such as Read, CPU Utilization and Burst are available at a click of the button and give you a good idea of how the hard drive can perform from system to system.



Here you can see that nVidia blasts ahead of the competition by about 20%. While a single drive is half the speed when compared to the nVidia controller it is only 35% slower then the fastest PCI option.



Here we see nVidia is TWICE as fast as the competing controllers and even the single drive running off the native controller is faster then the RAID PCI option. The Highpoint controller seems to lag behind quite a bit.



There is nothing between CPU Utilization but as you can see the single drive uses half as much, in this case only 2 - 3%.



Like CPU Utilization there is nothing in the access time. .2MS separates all the drives.
