Closer Look

The featured characteristic of the second generation of OneTouch drives has remained the same: there’s a button on the front side of the device which performs an instant back-up of important data from your computer. At the rear panel of the gray silvery case you can find a power-on button, a power connector, a USB 2.0 port, two FireWire ports, and a few vent holes. The drive is operational in horizontal as well as vertical position (on a special stand).

The OneTouch II family consists of three models of 200, 250 and 300GB capacities. The drives use 100GB platters and rotate their spindle at 7200rpm. The amount of cache memory differs, though. The junior model has a standard 8MB buffer, while the senior two models are equipped with a 16MB buffer. This fact, of course, can seriously affect the performance of the devices. The manufacturer specifies an average seek time of less than 0.9 milliseconds.

The support of the two popular interfaces (USB and FireWire) gives the user the necessary flexibility in connection. The specified values of the maximum sustained data rates have remained the same since the previous generation: 34MB/s with USB 2.0 and 41MB/s with FireWire. The drives are operational within a temperature range of 5 to 35 degrees centigrade. Their dimensions are 41x140x210mm, their weight is 1.38kg.




The accessories include a stand, a 6-to-6-pin FireWire cable, a USB cable, a power adapter, a software CD (the bundle features Dantz Retrospect Express HD Backup), a user’s guide, and a warranty. The manufacturer's suggested retail price for the OneTouch II E01G250 model is $310.

Testbed and Methods

We are going to check out the speed characteristics of the external drive from Maxtor in WinBench 99 2.0 and FC Test 1.0 on the following testbed:

  • Albatron PX865PE Pro mainboard;
  • Intel Pentium 4 2.4GHz CPU;
  • IBM DTLA-307015 15GB HDD;
  • RADEON 7000 32MB graphics card;
  • 256MB DDR SDRAM;
  • Microsoft Windows 2000 with Service Pack 4.

The drive was attached to the USB 2.0 controller integrated into the ICH5 South Bridge and to an external PCI FireWire controller based on the VIA VT6307 chip. We performed our tests with the generic drivers of the operating system.

To have some wider perspective, we will compare the Maxtor OneTouch II with a model from the first OneTouch series as well as with an external HDD from Western Digital, which has been the fastest in our earlier tests. These opponents both have the same capacity as the reviewed Maxtor and even support the same pair of interfaces.
