We're disappointed to report that the U5 falls far short of meeting its promising 8.9 millisecond seek time. Our measurements place the drive's access time at 19.4 milliseconds. This figure is easily the highest access time we've ever recorded... worse than even the 4400 RPM, 12 millisecond seek Quantum Fireball lct15. Subtracting the standard 5.6 milliseconds associated with 5400 RPM rotational latency yields a measured seek time of 13.8 milliseconds... nearly 5 ms off the mark.

Sequential transfer rates, on the other hand, are respectable. The Seagate's outer-zone measurement of 31.6 MB/sec edges out scores from competing Fujitsu and IBM disks. Likewise, its inner-zone score of 20.7 MB/sec sets a record for a 5400 RPM drive.

So, how do these rather unique scores translate into high-level performance? Let's move on and discover.
