#162385 - this all puzzles me
Responding to: ???'s previous message
I used to be able to do my daily backups, on 15GB-capacity tape drives, over the SCSI channels I had available, by sending them over the Ethernet. Now that I use fewer machines, I have a TB USB2 drive and it takes more than a day, despite the fact that the volume is much lower and strictly local, as I move the USB2 drive from box to box. I watch the process progress and see that it often drops out for half a minute or longer despite the fact there's no other activity.

Simple file transfers take very little time at all, but the transfer of entire "folders" takes a long time, and, as I said, appears to have significant breaks. It's quicker, by about 40% under Win98SE than under XP, but perhaps that's because of the different drivers.

Perhaps the solution lies in taking the PC out of the loop. That's not going to happen right away, though.

How would you guys do it?            01/01/70 00:00      
   Not sure Windows can do it            01/01/70 00:00      
      High-speed USB and a buffer            01/01/70 00:00      
         USB for DOS?            01/01/70 00:00      
            once you remove all the potential source...            01/01/70 00:00      
               Latency is the problem - not the transfer rate            01/01/70 00:00      
                  You're right ... it's the latency            01/01/70 00:00      
                     Just one machine?            01/01/70 00:00      
                        Nope ... it seems that all Windows boxes are slow            01/01/70 00:00      
                           The hw shouldn't be hobbled            01/01/70 00:00      
               I'd love to use USB, but lack faith in the OS            01/01/70 00:00      
                  Try other PC or deactivate devices if you get lockups            01/01/70 00:00      
                     this all puzzles me            01/01/70 00:00      
                        1.5GB/minute reasonable for backup to USB2 disk            01/01/70 00:00      
   lantronix xport ??            01/01/70 00:00      
      How would that help?            01/01/70 00:00      
   with PCI or ISA with dma            01/01/70 00:00      
      gigabit ethernet?            01/01/70 00:00      
         Gbit normally overkill            01/01/70 00:00      
         I've considered that ... I don't like the overhead            01/01/70 00:00      
            economical ways            01/01/70 00:00      
               Do those work with DOS?            01/01/70 00:00      
                  any of OS will do...            01/01/70 00:00      
            100Mbit Ethernet on 8051            01/01/70 00:00      
   Firewire will do it            01/01/70 00:00      
      That's probably too much overhead!            01/01/70 00:00      
   LVDS to PCI card            01/01/70 00:00      
   re: how            01/01/70 00:00      
      It's not that simple            01/01/70 00:00      
         ESCC is the best option            01/01/70 00:00      
         do you REALLY think            01/01/70 00:00      
            Shouldn't be a problem            01/01/70 00:00
