"Why is it that an interface that operates at 5 Gb/s never reaches corresponding transfer rates? Our investigation reveals that not all USB 3.0-based solutions are created equal, and we explore two technologies used to bolster the performance of USB 3.0."
Not getting the USB speed you felt was promised when you moved to USB 3.0? You may have seen advertisements suggesting USB 3.0 could bring you a maximum throughput of 625 MB/s. Not getting it? You are probably not alone. Tom's Hardware decided to have a look at the issue and see if there was a way to improve USB 3.0 performance. Indeed, there seems to be some good news coming in the future. In the meantime, a read through the Tom's article does a very nice job explaining why the theoretical throughput is not achievable, and what is being done to improve performance. It is a detailed read, but very interesting if you have pondered the performance question in the past.
