No, it seems this drive was developed this way. It is 2x 128Gb drives on one PCB. (see the link above) It works fine in the Acer laptop it was designed for. (at 256Gb) From what I can tell, it uses the same concept as an external, multi-drive enclosure, where there is 1 esata connector, made possible by way of a port multiplying controller on both ends.
The problem with using this drive in anything else is that most msata ports and msata to sata adapters don't support port multiplying, so they only see 1 of the 2 drives. The adapter I bought certainly doesn't support port multiplying. (or good manufacturing, but that is another issue) I also tried it in a FoxConn system with a native mSATA port, but it too only sees one of the two drives.
A search of google hasn't found anything confirmed to work. I suppose it is possible this might work: »
