603 Which HDMI adapter should I use to connect an HDMI monitor to an Echo Express Thunderbolt PCIe Expansion Chassis' Thunderbolt port?Mar-19-15
661 I'm using OWC Mercury Extreme Pro 6G SSDs with a Tempo SSD or Tempo SSD Pro adapter in a Thunderbolt Expansion Chassis and the system hangs after waking from sleep.Oct-01-16
You need to upgrade to OWC 6G firmware version 5.0.2 (released March 13, 2012) or greater.

714 Do GPU cards work over Thunderbolt on Windows?Nov-02-12
GPU cards over Thunderbolt under Windows are currently neither supported by Sonnet, nor the GPU card vendors, nor Microsoft.

Several GPU cards do seem to work with Windows if you boot the maching with the Thunderbolt chassis attached at boot time. We should also note that Sonnet Echo chassis don't currently provide auxillary PCIe power which several high-power GPU cards require. Furthermore, the power required by the card must to be under the rated power of the chassis less 10W for Thunderbolt, less the power drawn by a subsequent bus-powered Thunderbolt device, if any.

717 Is the Red Rocket as fast in a Sonnet Echo Express Pro chassis as in a Magma Express Box 3T?Oct-13-12
731 How fast will an SSD be in an Echo Express Thunderbolt chassis using the Tempo SSD, SSD Pro or SSD Pro Plus?Dec-30-17
We have performance comparison information on our web site. Check the performance tab on Tempo SSD or Tempo SSD Pro product page. This will give you a pretty good idea.

These numbers can be generalized. For one SSD you can infer from the table.
Read speed over Thunderbolt = 90% of rated read speed in a Mac Pro
Write speed over Thunderbolt = 80% of rated write speed in a Mac Pro.

Go to the manufacturer's SSD product page, check the speed rating and multiply by 90% and 80% for read and write, respectively, for performance over Thunderbolt.

For two SSDs in a RAID 0 in the Tempo SSD Pro using the original Thunderbolt 1 bandwidth limit, the speeds get capped at about 700MB/sec read and 560MB/sec write. There is no bandwidth limit for a two-SSD RAID 0 under Thunderbolt 2 or Thunderbolt 3.
