Today we are going to test the LaCie Rugged USB 3.0 500GB external HDD in both USB 3.0 and USB 2.0 modes on our GIGABYTE X58A-UD7 motherboard. USB 3.0 will have a solid advantage and at SATA II speeds with the Hitachi 7K500 7,200 RPM drive included with the system. The only real difference that we will notice is that USB 3.0 does not pass along NCQ information, something that is a real benefit to SATA and eSATA.
ATTO Baseline Performance
Version and / or Patch Used: 2.34
ATTO is used by many disk manufacturers to determine the read and write speeds that will be presented to customers.
USB 2.0 ATTO Performance
USB 3.0 ATTO performance
ATTO shows us that the LaCie Rugged USB 3.0 500GB HDD is able to achieve just over 106MB/s in reads and writes while using native USB 3.0.
USB 2.0 is limited to between 25 and 35MB/s with the LaCie Rugged. This is the upper limit of the standard so the drive is able to perform very well in USB 2.0 as well.
