7. eSATA vs USB2.0
We tested the transfer speed with USB 2.0, in order to compare it against eSATA. We used HD Tach and PCMark 05. Both tests were carried out with the NexStar 3 enclosure.
-HD Tach Tests
The test results, more analytically:
|HDD Test Suite||NexStar 3 on USB 2||NexStar 3 on eSATA|
|XP Startup (MB/sec)||6.952||7.836|
|Application Loading (MB/sec)||5.655||7.332|
|General Usage (MB/sec)||4.697||5.612|
|Virus Scan (MB/sec)||28.263||69.250|
|File Write (MB/sec)||25.369||56.153|
As we expected, the best performance came when using eSATA, with almost double the performance in comparison to USB 2.0.
