I am getting ready to install suse 10.2 on my Dell xps 410. This machine has a bad physical architecture. If you add a second HD, it is likely you won't be able to use the last of only 3 PCI slots. Also, two HDs cause it to hum loudly. So, I thought I would take my second SATA drive and buy a SATA to firewire enclosure. I read the specs on several such enclosures and they all indicate that on windows you can connect to USB 2.0 of firewire, but on linux only connect to USB 2.0. Since I also read that firewire can be twice as fast as USB 2.0, I want to use firewire. Does anyone have such a hookup?

I've not yet tried, but this is what I found last week when I googled: http://www.linux1394.org/ http://www.linux1394.org/faq.php http://ask.slashdot.org/article.pl?sid=01/11/14/1751223&mode=thread&tid=99 http://fwdepot.com/firewiredepot-forum/viewtopic.php?t=6 http://www.idevelopment.info/data/Unix/Linux/LINUX_InstallingIEEE1394FireWir...

Firewire is twice as fast as usb 1.1, but not as fast as usb 2.0 There is a new firewire slowly starting to appear that will be about twice as fast as existing usb 2.0 (or existing firewire) but I've not actually seen this in production yet. You would be better off with a external scsi enclosure if you want my opinion. -- _____________________________________ John Andersen

How might I do this? I can get a PCI to SCSI card, but can't find a simple SATA to SCSI enclosure. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Presumably you mean SCSI to SATA. SCSI interface, SATA drives? Why does it have to be that way? SCSI enclosures are a dime a dozen and by the time you track down a hybrid you will not save any money. Just go SCSI. The first google hit I found was http://www.bixnet.com/exscsi3hardr.html Or you can DIY http://www.makezine.com/blog/archive/2005/11/convert_a_scsi_enclosure_into.h... (Sata allows for fairly long cables). -- _____________________________________ John Andersen

My Dell has only SATA internal connectors(5). I don't have a scsi HD, only an extra SATA internal that I can't mount internally. I will probably end up running a SATA data cable through my computer case to provide an external SATA connection. That way I won't use my last PCI slot for an external SATA connection, as in the DYI article. I have also located a relatively inexpensive SATA enclosure that has SATA output. I should be able to use this and not need to modify a scsi enclosure. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

There is a new firewire slowly starting to appear that will be about twice as fast as existing usb 2.0 (or existing firewire) but I've not actually seen this in production yet. AFAIK, Firewire 2, 800Mbps does exist for years. Maybe it's becomming

It is often called FW-800 and it has been around a couple of years. There are many devices using it. The first FW is called FW-400. BTW, FW-400 is typically faster than USB 2.0 in many uses. Especially streaming images. On our FW-400 system, we actually get 400 MBit of data (calculated with cameras that provide an uncompressed image size/rate). I am not sure if the USB 2.0 speed is for the data only, or it if includes the transmission overhead. -- Roger Oberholtzer OPQ Systems / Ramböll RST Ramböll Sverige AB Kapellgränd 7 P.O.

Sound like your unique setup yields atypical results. USB2, with proper cables (yes it does matter) outperforms Firewire 400 for bulk data transfer. I have 3 different extern chassis disk drives each with dual interfaces (fw and usb2). Transferring large file volumes across the wire is slightly faster using USB2. One of these devises if VFAT and the USB performance in windows XP exceeds Firewire. The others are ReiserFS, and used for linux only, but still USB2 beats firewire. Long backups take 40+ minutes using Firewire, the USB finishes in 34 to 36 minutes. disk will finish -- _____________________________________ John Andersen -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Everything I've heard suggests that getting faster net transfer with USB (2.0) than FireWire (400) is the atypical case.
