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
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.

1095 I'm using this card with macOS 10.15 and am experiencing Kernel PanicsMar-15-20
Open System Preferences, Energy Saver, and uncheck Put hard disks to sleep when possible. Sleep is not needed for SSDs, and macOS 10.15 seems to have a problem with sleeping SSDs when possible.

1183 The Write performance of my SSD is very slow under Windows.Feb-14-23
The Windows default for any external storage media is for Write Caching policies to be disabled. If you have enabled it, then the write performance to an SSD will be very slow. To get significantly increase write performance, disable Write Caching. For instructions, see this Microsoft Document.
