Video-editing on-the-move (e.g. on a train) using a MacBook Pro (laptop) with Sony Vegas 9 (64-bit) as NLE (under Boot Camp / Windows 7), my practical experience was that a GRaid Mini external drive was far, far better than a 5400 rpm Western Digital “Passport” drive. Consistent with the dual use of the MacBook, I partitioned the drive for both NFTS (Windows) and HFS+ (Mac OS), 50-50%. Due to Boot Camp limitations (explained below), up till now I only ever used it “tethered” to its own mains-based power supply. But now I see it can also be used mobile, powered from the MacBook – something that up till now I could only achieve under Mac OS, not under Windows.
When using Boot Camp / Windows on the MacBook, I initially tried the shirtpocket-sized Passport drive because it was small, light and powered from the laptop’s USB port. While its data throughput wasn’t too bad, at least for single-channel HD editing (especially when only 1280720), when it came to cuts from one video clip (hence, in my case, video file) to another, there was a frustrating delay every time.
I also have a GRaid Mini drive, but it wasn’t obvious at first how to use it mobile when using Windows (on a MacBook). That drive consists of two 7200 drives in RAID-0 configuation (striped, giving speed but no redundancy), and appears just like any single drive to the computer (no RAID management etc. needed). The drive has not only a USB (2) port but also FireWire 800 (FW800) and eSATA ports. While the latter two options work fine with the MacBook under Mac OS, they don’t work under Boot Camp / Windows. I have tried many times and trawled many forums, no solution is apparent. Under Mac OS the eSATA drive would ordinarily plug into an ExpressCard adaptor plugged into the laptop’s ExpressCard slot, but under Boot Camp / Windows, the ExpressCard slot doesn’t work, while for the FW800 port under Boot Camp / Windows, it appears to work at first but eventually crashes as a device when it attempts to communicate data (e.g. when copying files).
When connected only by USB to the MacBook under BootCamp / Windows, the GRaid Mini is not powered from that port, hence up till now I have relied on a mains power supply to that drive. However, I discovered if, after first connecting by USB, you subsequently connect also by the FW800 lead, then the drive takes power from the FW800 yet communicates data via the USB lead. Hooray! I can use it on-the-move then!
The order in which the leads are connected is vital. If by mistake the FW lead was connected first, then the drive would sense that as the data communications route, and subsequently fail in use. It is vital that the USB connection is made first. Likewise, on disconnecting the drive (following “ejection” by the computer’s file-system), disconnect the FW drive first. The rule is FW lead: connect last disconnect first.
My experience of editing with the GRaid Mini is far more fluid hence more pleasurable and efficient. Totally worth it. None of the per-cut delay effects of the 5400 rpm Passport drive. And now it can be used on-the-move, even with Boot Camp / Windows on a MacBook. I just wish Apple would fix that Boot Camp isue with FireWire and ExpressCard ports!
