Specifications, Availability and Pricing
The Silicon Power eSATA Portable SSD is a 4 channel controller that is able to use both USB and eSATA interfaces for connectivity. This works out really well if you are using on a daily basis a mix between old and newer PCs where some systems may have eSATA and others do not.
Silicon Power is making the portable SSD in 8, 16, 32 and 64GB capacities. DVNation lists the 64GB version that we are reviewing here today for 211.00 USD. Newegg currently sells the Super Talent Luxio 64GB drive we reviewed back in March for 149.00 USD, so there is a little more than a 25% increase in cost added to get the eSATA feature.
When it comes to speed eSATA clearly outperforms USB with data transfers up to 90 MB/s with the Silicon Power eSATA Portable SSD. The most I have ever achieved with USB is around 32 MB/s and that was under ideal conditions with a really fast Kingston HyperX flash drive.
