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.

1064 In a Mac Pro, can I install Windows on a Tempo SSD or SSD Pro Plus?Jul-15-19
You can't run Bootcamp on the Sonnet Tempo SSD or SSD Pro Plus. However, you can format the SSD on the Tempo SSD or SSD Pro Plus with a GPT (GUID) partition map, install Windows 10 in UEFI mode on one SSD, and boot from it.

You must install the Bootcamp drivers (not the Bootcamp assistant). To get the Bootcamp drivers you start Bootcamp and look for a menu item to download Apple support. That downloads machine specific Apple drivers. There may be a way to get those drivers directly from Apple's website but we don't have the link. You must install this support before the machine reboots after a Windows install. Note that when the Windows installer sees the GPT partition map, it defaults to UEFI mode.

Note that option-boot will not work. This is how you select the startup disk...
•If you boot the macOS, you can open System Preferences->Startup Disk, and select the Windows disk
•If you boot Windows, you open Control Panel->Bootcamp and select the macOS disk. (When you install the Bootcamp drivers, you get this control panel in Windows that lets you select the macOS.)
•Or, you can zap the PRAM, which will default back to the maOS.

Only Windows 10 is supported; and there is an install order if you put macOS and Windows on two SSDs (install macOS first, Windows second). Be prepared to clean the disk and install more than once; the Windows installer sometimes hangs during the install.
