Aside from our subjective evaluations, we let the 1.8" Portable Hard Disk stretch its legs on some benchmarks.
WinBench 99 clocks the PHD at an effective disk access time of 20.5ms, a figure akin to older desktop drives such as the Seagate U Series 5. The PHD's outer-zone sequential transfer rate (STR) is 19.7MB/s, while the inner-zone scores 10.5MB/s. These low-level measurements translate into Disk WinMarks of 6090 (Business) and 7510 (High-End).
The IPEAK SPT's Read Service Time analysis closely corroborates the effective disk access time given by WinBench 99, giving an average value of 20.6ms. More interesting is the Write Service Time analysis, which pegs the PHD at 12.7ms. CPU utilization maxes out just a hair over 20%, which is well within the standards of desktop IDE drives.
Overall, while certainly not as speedy as any run-of-the-mill 7200rpm desktop hard drive, the PHD delivers pretty impressive performance while still maintaining silent and cool operation.
