I am very satisfied with this product. I bought this duplicator because it clones hard drives with both a 512 byte physical sector and a 4 KB physical sector. The last cloning dock I bought was the Vantec NexStar USB 3.0 Duplicator (NST-DP100S3) which is limited to cloning hard drives with 512 byte physical sectors, which is stated in the product description on the Revain or Vantec website was not explicitly stated. Don't worry about formatting your hard drive with StarTech Duplicator as it easily clones 512 byte sector and 4 KB sector 22GB/m drives with offline capability. Please note that according to a StarTech Customer Service Representative I spoke to, this version I'm reviewing, SDOCK2U33RE, has twice the offline copy speed of the less expensive SATDOCK2REU3 version. This is just my first analysis and I intend to do more thorough testing.
