Testbed and Methods
As you may have already guessed we will stick to the same testing methodology as in our previous test session mentioned above. We estimated the efficiency of the enclosure in question with the help of a Hitachi HDS722525VLAT80 hard disk drive. Its potential performance is high enough to ensure significant workload on the SATA interface, that is more powerful than the previously considered USB 2.0.
We used WinBench 99 2.0 and FC-Test 1.0 to investigate the speed characteristics of the hard disk drive. The testbed was configured as follows:
- Albatron PX865PE Pro mainboard
- Intel Pentium 4 2.4GHz CPU
- IBM DTLA-307015 HDD, 15GB capacity
- RADEON 7000 32MB graphics card
- 256MB DDR SDRAM
- Microsoft Windows 2000 with Service Pack 4
Of course, the results obtained in this test session will be compared with those obtained in our previous test session (for details please check our review called Two 3.5" External Enclosures for Hard Disk Drives with USB 2.0 Interface).
Performance in WinBench 99
We will start the discussion of the Winbench 99 results with the internal transfer rate measurements:
As we see, the bandwidth of the SATA interface appeared just enough not to spoil the nice and smooth transfer graph: perfect stepping shape exceeding the 60MB/s point.
