## Questions & Answers

**Q: If i used this for adaptec raid controller, will performance be the same as if installed on the server motherboard?**
A: We expect the Adaptec RAID controllers to have an adequate cache to support Thunderbolt performance that is similar to motherboard performance.

**Q: Is it possible to use it with pro tools hdn card and aja lhi,  with a new macstudio?**
A: Hello Michael, The ProTools HDX card does not fit in the Echo Express SEIIIe. You would need an Echo III, which supports the full-length HDX card and works with the M1 Macs.

**Q: Will this work with older server class sas/sata raid cards - specifically lsilogic sas9260 or other cards from that generation?**
A: You would have to ask the card maker whether their driver is Thunderbolt compatible, which usually means that the driver needs to gracefully handle hot plug/unplug. Drivers that cannot handle hot plug/unplug may still work if you plug/unplug the Thunderbolt chassis from the computer only when the computer is shut down.

**Q: Will this work on a Dell PC?**
A: Thunderbolt drivers are provided by Intel, so yes, it should work
