The one area we didn't really touch on today is the fact that the Duet can run two drives at the same time. The catch is there is only so much bandwidth to and from the enclosure, so if you are reading or writing to both drives at the same time you will divide the bandwidth between the two. This division will rarely be a perfect 50 / 50 split since one drive will be faster than another.
The Thermaltake BlacX Duet is a unique product that's designed for users who need access to multiple drives easily. Being able to quickly add two drives doubles the convenience factor and gives users the opportunity to copy from one drive to the other without the need to open the computer case. Software such as Acronis will even allow users to mirror data from one drive to another. Anyone working in the computer service field needs a Thermaltake BlacX Duet permanently attached to their system's eSATA port.
When it comes to performance, eSATA delivers more than enough bandwidth for traditional platter drives even when connected to the subpar JMicron bridge chip. Users looking for the best eSATA performance can invest a couple of dollars in a SATA to eSATA adapter. These are available for less than 5 Dollars online and many motherboards even ship with them included in the accessory package.
Thermaltake has a well-established list of retail and e-tail outlets, so finding a BlacX Duet will be simple enough. Newegg currently lists the Thermaltake BlacX Duet for 44.16, but after a mail-in rebate the cost goes down to 34.16. This is less than the single drive USB 3.0 BlacX 5G and in my opinion the Duet is better value and offers more convenience.
