Description: English instructions for installing the Thunderbolt 3 upgrade card into Sonnet's xMac mini Server 1U rackmount enclosure/Thunderbolt-to-PCIe card expansion system. See Thunderbolt 3 Upgrade Cards product page for important compatibility information.
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.
