The OXFW911+ is quite a good chip. It is responsible for the FireWire interface. The Cypress chip is for the USB2 side. Both are AFAIK fully independent of each other.
During the past few years I heard of only a single report of an 911 or 911+ with bad firmware, which is negligible compared to other chip types. The transfer speeds could be realistic if observed with filesystem overhead. Especially some filesystems which are not native to Linux are slower. Also, filesystems which are very much utilized (90% full or so, depending on the filesystem and usage patterns) may get noticeably slower. "hdparm -tT" would show raw read speed without filesystem influence. (Execute three times to get reliable numbers.) 3.5" FireWire 400 disks, when used through Linux' ieee1394 driver stack, should get somewhat more than 20 MB/s when measured this way. There are also new Linux FireWire drivers in the works which go above 35 MB/s with FireWire 400 disks, but these drivers are not yet mature and hence not yet enabled in most distributions. -- Firewire connection not being correctly mounted in 6.06 https://bugs.launchpad.net/bugs/53746 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
