Terastation II, with 4 x 1GB drives, newly rebuilt RAID 5 array. Latest firmware (2.14)
Connected to a Windows XPSP3 box via gigabit switch, Both devices have a Gigabit card.
Backups run extremely slowly, on the order of 1Gb per hour. Size of test backup job is 50Gb.
Have eliminated the backup program and its settings as the cause of the issue since the same job will backup to USB in about three hours.
Ethernet cables are new and known good.
Switch works fine for every other use (streaming media, etc.)
Not sure what to look at next. Any ideas?
Thanks.
(more subjectively, this NAS has been back to Buffalo once already for hardware problems.)
