Keep in mind that we were using a beta driver, so hopefully these limitations aren't necessarily permanent. NOTE: As of November 2nd, 2005, the hot-swap feature is functioning A-OK. FireWire has spoiled us to expect external drives to mount on the fly. That's an important feature since most users don't want to Restart their PowerBook just to mount an external drive. The Cardbus SATA PC card doesn't support HOT-SWAP.

In the meantime, if you buy this card, plan on using it with only one drive for the time being.Ģ. Hopefully this can be addressed by tweaking the driver and is not due to bus contention. In a striped RAID 0, the sustained WRITE speed was only 32MB/s. When the Duplicate began, the QuickBench sustained write speed dropped from 70+MB/s to 18MB/s. We tested this by starting a QuickBench run on one while duplicating a large file on the other. When we mounted two independent drives, and both drives were busy, the write speed dropped way down. Our pre-production version had a two shortcomings:ġ. But I am impressed at the performance of a single SATA drive using the 2 Port Serial ATA Cardbus PC Card on our lab's G4 PowerBook. Knowing Cardbus is 32 bit and 33MHz, I was skeptical.
