I raised a ticket with ASUS yesterday explaining my issues with Sandforce SSDs on RAID 0 using Intel RAID and asking if there was an ETA for the updated BIOS.

This is the reply:

Dear Valued Customer,

Thank you for contacting ASUS Customer Service.

My name is Rocky and it's my pleasure to help you with your problem.
Hello,

You may use the SATA drivers from the following page for a chck:

Maybe you can update the chipset driver and check again:

If no effect, please change the hard drives and use the latest firmware available for a further check.
And according to the time interval of the previous BIOS versions, I think the new version should be updated recently. And hope you understanding.

In a nutshell "I can't give you a date, sorry"

Can someone?
