Fusion PCIe TB2 = Sonnet Technologies PCIe Flash Drive (bus-powered from Thunderbolt 2 port on any Mac)
Tempo PCIe MPt = Sonnet Technologies PCIe 3.0 SSD (SM951 flash mounted on a PCIe M.2 board and installed inside a 2010 Mac Pro's x4 PCIe slot #4)
miniSwap USB3 = FirmTek miniSwap/U3 bus-powered USB 3 enclosure with Samsung 850 EVO 6Gbps SATA SSD connected to the USB 3.0 port of the iMac 5K
LARGE SEQUENTIAL TRANSFER TEST
We used AJA System Test to benchmark file level sequential transfer speed using a 16GB test file (and 4K frame size). RED graph bar means the fastest overall in Megabytes per Second.
I've been dreaming of a bus powered Thunderbolt 2 storage device that achieves the maximum real-world speed of Thunderbolt 2. The Fusion PCIe with its fast Flash module is a dream come true.
As you can see from the graph, it rivals the speed of the Tempo PCIe 3.0 SSD -- the same SM951 flash storage module mounted in the PCIe bay of a 2010 Mac Pro tower -- technically bus-powered storage, too.
Finally, up to now, the fastest (and only) bus-powered external flash storage for contemporary Macs used USB 3.0. We included the fastest example of bus-powered USB 3.0 storage (FirmTek miniSwap/U3 with Samsung 850 EVO 6Gbps SSD). You can easily see the advantage of the Fusion PCIe Flash bus-powered Thunderbolt 2 storage device.
One more thing: The Fusion PCIe Flash Drive can be used as Boot Volume.
