I once had to move 750 GB to two FW drives because I had to rebuild a SATA2-RAID on a different controller. At that time, my FreeBSD6.2 notebook (with Firewire on board) even seemed a bit faster (with USB2) than the SLES9 server (Dual Precott Xeons) with Firewire 800. But FreeBSD also crashed from time to time, though it seemed to handle bus-resets and link-losses a bit better. Getting a card that was supported on SLES was funny anyway - SuSE would not recommend a card to buy, because nobody knows which cards contain which chips. If it doesn't work, buy another one. Repeat until it works.... More recently, a 1 TB WD "MyBook" (USB) just died in the process of moving 700 GB of files on it. Moral of the story: - Firewire is cool (I _love_ the target-mode in my Macs), but the implementation sucks most of the the time. - USB2.0 doesn't suck much less. It's just used more widely and obvious bugs show up often enough so that they might get fixed (in a revision of the hardware you don't own...) - in my book, USB means "Useless Serial Bus" - because it's obviously not suited for much more than keyboards, mice and the occasional camera) Rainer -------------- next part -------------- An HTML attachment was scrubbed...
