I had bought especially for hard drives to check this product for errors. For this, the so-called SMART values must be read. Unfortunately, this product is a controller of Prolific is installed (Vendor ID: Device ID 067b: 2773) and the works of smartmontools not together with the developers. For that alone I just need to pull two star.
To create backups this dock will but enrich my private work.
I had the variant USB 3.0 Docking Station for all 2.5 "and 3.5" SATA hard disks and SSD's in February 2012 - HDD Auto Detection - incl. Eject button - Backwards compatible - Black bought which continues to be performed in front of their service. Compared to DUAL variant here a controller from JMicron is used (152d: 2339) which also allows the SMART values of the hard drives auszulesene for smartctl has the option to be used -d usbjmicron (.
Unfortunately, I can give only one review on these two completely different products. The "older" version had received from me 5 stars.
