Our next stop was deep within the pages of several tech site reviews where we found a large number of AData XM11 included Zenbooks with great performance results, but we could not find a review with the Sandisk U100 SATA 3 SSD. In fact, it wasn’t until our review of the Samsung PM830 SATA 3 SSD that we had even considered the viability of a Zenbook purchase, this being the result of an unhappy reader asking why we weren’t testing a SATA 3 mSATA SSD in a system for which it was intended, rather than on our Test Bench. It seems there was no way of identifying the SSD on the exterior packaging and the first signs of SSD identification were found on the interior box which would be seen after purchase.

We will be the first to concede that we are not the first to explore this topic as AnandTech covered it some time ago in their Asus Zenbook UX21 Review quite well and we had since received a few e-mails from unhappy customers whom had unknowingly received a system containing the SSD that was not of their choice. We believe ASUS should be clearly identifying the SSD on exterior packaging and within specifications just as they would a CPU, especially since the SSD is responsible for the largest visible upgrade we see in computer performance today. Our concern, in fact, led to our investing in one of each Zenbook (AData/Sandisk), and then voiding the warranties to confirm SSD configuration, so that potential buyers have a clear view of this. The performance drop between the two is significant. There is no price difference between the two, the product number is the same and the consumer has no way of knowing which they will receive. Within the ‘Zen’, ASUS may provide either of two SATA 3 SSDs, these being the AData ‘SandForce Driven’ XM11 or the Sandisk U100. This report closely examines the ASUS Zenbook. If we told you that we spent $2400 to right a wrong in proving something that you as a consumer should be aware of, would you believe us?
