Sync/Frame Drop Issues With BlackMagic Intensity

Hooked my BlackMagic Intensity Shuttle up with VirtualDub and tried to capture in UtHD. Worked just fine once, but now everything I capture gets out of sync by six or seven seconds by the end.

I'm capturing on a laptop, to a USB3.0 RAID0 drive. I've also tried capturing in 8- and 10-bit YUV via the packaged BlackMagic software, but it drops a frame every 5-20 minutes depending on format.

According to the Disk Speed Utility my RAID0 is fast enough most of the time for 27-28fps at 1080, with a checkmark next to both read and write for 1080i50 in 10-bit for both YUV and RGB...most of the time. Intermittently it drops significantly (from around 150-160 to sub-120), managing only 18fps at 1080.

While capturing to MJPEG does work fine, it means a lot of screwing around to fix issues with field order and color shifts, so I'd rather avoid it if possible.
