Teac HD-15C-OTC, 250GB and 300GB

These two HDDs are especially interesting as they offer an eSATA interface besides the traditional USB. The eSATA interface cannot provide power to the external HDD, so there are two variants of powering the latter. You can use an external power adapter, which is problematic because no adapter is included into the kit whereas the eSATA connector has nonstandard polarity (the “minus” corresponds to the central pin and the “plus” to the outer pin rather than vice versa). Or you can connect the drive via both USB and eSATA. In this case the HDD is powered by the USB and transfers data via eSATA.

The HDDs are nothing special on the outside: a typical black “cigarette-case” with two interface connectors, a power connector (for the missing adapter) and a button all in one butt-end. Having installed the included software on your PC, you can press the button to back up your data to the external HDD according to the specified settings. That’s a nice addition to the drive’s functionality, but the button might have been bigger rather than just a section of the metallic panel that you can press.

A neat pouch for carrying the drive is included into the kit but no eSATA cable could be found.

When connected to a PC, the 250GB and 300GB models were identified as Fujitsu K2200T762 and Fujitsu K201T782 respectively. It’s clear about the second model – it obviously comes with a MHX2300BT hard disk. As for the 250GB model, we have to wait for the tests to show us, just like with the above-described HDD from Fujitsu of the same capacity.

Running a little ahead, we can tell you that we tested the 300GB model using both of its interfaces and the 250GB model with the eSATA interface only.
