    As per LaCie's specifications, their eSATA Hub Thunderbolt Series does not allow eSATA port multipliers.

    However in the comments on the apple store review page for the device there are two owners who claim they have it working:

    Unfortunately this doesn't list which enclosure is used

    The Thermaltake BlacX Duet info is here: http://www.thermaltakeusa.com/Product.aspx?C=1346&ID=1895

    Which states:

    In other words it looks like there is limited support for port multiplication in the Lacie eSATA Hub. I hope in this thread we can establish a list of devices that have been tried to work - or confirmed not to.

    That makes sense, thanks!
    But it would also mean that the Thermaltake BlacX Duet wouldn't work, as it states it requires a host system with eSATA port multiplier. Strange that the Apple Store review claims it works. Maybe he's only using one disk at a time.

    Those Datoptics towers look really nice but a bit overkill. Would be happy with an enclosure capable of doing two disks and perhaps use RAID 0 (with SSD's).

    I tried a number of eSATA enclosures but speeds were disappointing. It seems that they all dropped down to SATA I. I've now connected two 256GB Samsung 830 series directly to the Lacie via eSATA to SATA cables and a SATA power supply. I've set them up as a 512GB RAID0 via Disk Utility and get 357 MB/s write, 463 MB/s read. Looks like a keeper.

    No it means the host must support port multipliers (i.e. be compatible with port multipliers). Some host eSATA ports are not compatible with port multipliers.

    The Thermaltake BlacX Duet has a port multiplier built in. When you connect any port multiplier to a host port that does not support it, only one drive (drive 0) is seen. When you connect the Thermaltake BlacX Duet to a host port that supports port multipliers, both drives will be seen. In other words, the Thermaltake BlacX Duet is no different than any other port multiplier device.
