Decklink mini Recorder / Frame drop

Hi

I bought Decklink Mini Recorder for PCIe. (Win7)
And I'd like to capture via Blackmagic Media Express.
But I met error like this.

frame_drop.png (77.16 KiB) Viewed 714 times

So, I checked my HDD speed.

My video source : HD 1920X1080i 59.94

Should I upgrade harddisk? or need I raid 0 1 5 system? or SSD????

And else I need to check for this?

Thank you.

You either need faster hard drives or capture as motion jpeg
