|I have small home wireless network running 4 |
PCs all running Windows XP SP3. All have
installed all the latest MS updates and
network peripherals have latest firmware
I recently upgraded the network router to a
Linksys WAG320N wireless N dual band
router and upgraded all the PC wireless
USB adapters to Netgear WNDA3100 to
connect to the new router.
The router has a USB port that allows an
external hard-drive to be connected so it can
be used as NAS by all the machines on the
network. I've connected a LaCie HD Max
2TB hard-drive to this USB port.
My problem is that I've noticed it was taking a
very long time to write to the HD. It takes over 15
minutes to write an 80MB file from a network
PC to this HD but to read that same file to a
network PC takes less than 30s.
I used Windows Task Manager to watch the
network activity. During the "write" activity it
showed a cycle of 25% utilisation for a few
seconds, then no traffic for 20s which repeats
until the transfer is complete.
However, when reading from the HD to a
network PC, the network utilisation is constant
at 40%, so is much, much quicker.
Why such strange behaviour on the network
when writing to the HD and really poor
performance, yet blistering transfer
speeds when reading from it? Is there a
problem with write buffering on the HD here or
is this just a feature of connecting a HD to a
USB port on router?
