Iomega HDD 20 GB in the test: External hard drive for USB 2.0

Write speed

The most important task of a hard disk after reading is writing data. We have shown the USB 1.1 Thumbdrive in this context in the diagrams, even if its writing speed of 150kb/s cannot keep up with real hard drives in any way.

In general, it can be said that the write performance of the hard disk is only slightly below the quiet Operating mode suffers, so this function should definitely be activated for a quiet system. Iomega's hard drive has to line up at the end of the test field in all write tests. The lack of performance compared to the DJNA is not particularly serious, however. Nonetheless, the performance of the external drive is remarkable.
