HD Tune is a Hard Disk utility which has the following functions:
- Benchmark: measures the performance
- Info: shows detailed information
- Health: checks the health status by using SMART
- Error Scan: scans the surface for errors
- Temperature display
HD Tune may also work with other storage devices such as memory cards, USB sticks, iPods, etc.
The Western Digital VelociRaptor gives the best of both worlds when used in RAID 0; high sustained transfer rates and low access times. Just imagine what you computer would be like moving data at an average of 175 MB/s .
EVEREST Average Read Access
EVEREST Ultimate Edition is an industry leading system diagnostics and benchmarking solution for enthusiasts PC users, based on the award-winning EVEREST Technology. During system optimizations and tweaking it provides essential system and overclock information, advanced hardware monitoring and diagnostics capabilities to check the effects of the applied settings.
CPU, FPU and memory benchmarks are available to measure the actual system performance and compare it to previous states or other systems. Furthermore, complete software, operating system and security information makes EVEREST Ultimate Edition a comprehensive system diagnostics tool that offers a total of 100 pages of information about your PC.
With the platters moving at 10,000 RPMs data can be accessed faster than on 7,200 RPM drives. Here we see that even with two drives in RAID 0 the average access time is only 7.2 milliseconds. Some 7,200 RPM drives take up to 15 ms in the same test.
Passmark Advanced Disk Tests
This Advanced Disk Test, which is part of PerformanceTest, measures the data transfer speed when reading or writing data to one or more disks. The speed that data can be transferred between memory and a hard disk drive is one of a system's most important performance aspects. There are quite a few factors which have a bearing on this speed and the Advanced Disk Drive Test allows the user to vary most of these factors and compare the results.
Even when the VelociRaptors are used in RAID 0, they perform well in Passmark's Advanced Disk Tests.
