ES1640 - Failover - Any Losts?

Hello,

Are there any Losts when a controller is going down or is it a true and full Active/Active box? As from big Vendors like EMC, HP, Fujitsu and so on?
So is for example the Write-Cache lost or is it synchronized immediately and before writing to disc and before say to the os that it has been written?

Thanks

Daft question, if data is lost Qnap would be out of business.
