I'm in the market for an external drive enclosure, and I want it to have an Oxford Semiconductor bridge chipset supporting FireWire 800 and eSATA. Does anyone know what the difference is between the Oxford 924DS chipset and the 934DSB chipset? I figure the 934 must be newer, in part because the 924 is not listed at all on this page at the company's website: http://www.plxtech.com/products/consumer/das. (PLX aquired Oxford Semiconductor in 2009.) I ask because I'm debating between two similar "quad interface" enclosures: The "OWC Mercury Elite-AL Pro" (http://eshop.macsales.com/item/Other%20World%20Computing/MEFW924AL1K/) apparently uses the older OXUF924DS chipset, a 3-amp power supply, an (arguably?) better reputation, and cost $95 including shipping. The "Rosewill RX81-MP-SC- SLV" (http://www.newegg.com/Product/Product.aspx?Item=N82E16817182123) uses the newer OXUF934DSB chipset, a 2-amp power supply, and cost $60 with free shipping. Experiences with either of these enclosures would also be appreciated. I've got an early 2008 27" iMac, and I plan to install a 2TB drive in the enclosure and to daisy-chain it on the FW800 bus, along with my "Seagate FreeAgent Desk for Mac" (which I believe has the 934 chipset). Usage would include importing MiniDV clips and iMovie work.
