Build a business case: developing custom apps

For benchmarking, I’ve run HDTach to assess the performance of various USB 3.0 drives and interfaces in recent reviews. The results show the Iomega eGo Desktop drive took an acceptable performance hit of 3MB/s when performing read operations and a rather less than pleasing 19MB/s loss in its writing ability.

Hd Tach Benchmark Tests

Iomega eGo Desktop

Iomega eGo Desktop drive test results from four different interface cards
MB/s: longer bars are better, CPU: shorter bars are better

Iomega eGo Portable

Iomega eGo Portable drive test results from two different interface cards
MB/s: longer bars are better, CPU: shorter bars are better

The performance with the portable drives is rather more consistent when compared with Iomega’s own 34948 PCI express card. Despite USB 3.0 connectivity, regardless of card interface, in tests Iomega eGo Portable simply couldn’t exceed 66.3MB/s. Comparison’s with LaCie’s Rugged drive actually saw a 5MB/s boost in write speed over other adapters. However, even this speed increase on the Rugged drive couldn’t match the figures achieved on the eGo Desktop test.
