Ken,

Do not confuse Mb (megabit) and MB (megabyte)...
You nic at 100Mb/s will transfer (assuming no overhead at all), 12.5
megabytes per second. This means that the max throughput over 15
minutes is (12.5*60*15 = 11250 MB = 11GB).

I just did a test transfer from my 160GB Linkstation to my computer:
I copied a single 0.99GB file (1,073,565,696 bytes) from the LS to
my computer. The LS is directly connected to my computer's Ethernet
port and the computer was doing nothing else that was CPU consuming.
I would consider this to be pretty much the ideal situation. The
transfer took 2 minutes and 36 seconds.

This translates to 1073565696/156 = 6881831 bytes/second = 6.56MB/s
= 52.5Mb/s. Just slightly above half of the 100Mb/s "theoretical"
transfer rate.

Now if your LS is connected to a router/hub and you're writing to
the disk instead of reading, you'll be getting close to 5MB/s (or at
least not much more than 6.56MB/s...) ;-)

Regards,
Daniel
P.S. 5GB in 15 minutes is 5.69MB/s... :-)

Ken,
I am with daniel on this. The excepted speed of the linkStation
(using samba) is 5MBytes/sec writes and 7Mbytes/sec reads. A lot of
tests have been run on various OS versions and still validate these
numbers. Some will get slightly lower depending on network
conditions and computer setups. You are never going to get
94MBytes/sec out of a LS. :-)
The only way to speed it up seems to be changing from Samba to some
other protocol without as much latency built-in. Even my 1Gbit
LinkStation does not get much better performance either.

Ken,
I am with daniel on this.  The excepted speed of the linkStation
(using samba) is 5MBytes/sec writes and 7Mbytes/sec reads.  A lot of
tests have been run on various OS versions and still validate these
numbers.  Some will get slightly lower depending on network
conditions and computer setups.  You are never going to get
94MBytes/sec out of a LS.  :-)
The only way to speed it up seems to be changing from Samba to some
other protocol without as much latency built-in.  Even my 1Gbit
LinkStation does not get much better performance either.
