Overclocker 28 Nov 2002

Benchmarking

Our test environment :

• Intel Celeron 1.2G
• FIC FS35T
• 256M SDRAM
• Seagate Barracuda IV 20G IDE ST31200A in FAT32
• Seagate Barracuda V 120G SATA ST320029AS in FAT32

We will be running 4 popular HD benchmarking programs on the two drives.

• ATTO Disk Benchmark
• HD-Tach 2.61
• Sisoft Sandra 2003 File System Benchmark
• ZDnet Winbench99

ATTO ExpressPro-Tools Disk Benchmark

ATTO ExpressPro Disk Benchmark is a configurable utility that not only benchmarks but can be used to tune the disk performance for applications. In our test, we selected drive c (IDE 20G) vs drive i (SATA 120G) and both runs in Direct I/O mode. To simulate real world applications, we chose overlapped I/O. The graph below shows that benchmarks of the standard IDE Seagate ST32100A 20G HD. It can be seen that at around 32KB transfer size, it reaches a read/write of 38MB/s.

In Fig 2, we benchmark the SATA HD using the same tool and configuration and it is not difficult to see that at 16KB block size, the system is maintaining a read/write of 40MB/s on the average. The difference is around 8% between the two drives
