Network Attached Storage, strange slowness

I use built linux boxes for my NAS storage running samba, and a "move" operation stays local to the linux box, even when initiated thru windows explorer from a client machine. Works fine.

This is very true, a move should be instantaneous. My post above centered around a copy command. Crossing any partition boundary (e.g. moving things from drive c: to drive d:) is considered a copy. Perhaps the Terrastation assumes that with how the folder is created, a copy is required. :dunno
Not knowing how the Terrastation works internally is my gap.

Yes that was my question too.
I also created a public folder and (because I set up security on share level) I had to create this as a seperate share and thus the move turned into a "copy like move".
Shmokes, does a move work fast if you move a file into a subfolder of the folder it is in? (like P:\Folder\Bigfile.avi to P:\Folder\SubFolder\Bigfile.avi)
boykster:
good points on crossing a partition boundary; I have no clue how the terastation is carving up the space and presenting it.

Ouch...
You guys should get some 802.11g or n gear and ditch the .11b.
In any case, wireless is like an old hub - shared medium, not dedicated like a switch. 802.11b is 11mb half duplex which means the max you'll get is 5.5mb. Subtract speed for distance away from the access point and for obstacles or interference from 2.4GHz cordless phones or other access points and you'll end up with 1 to 2Mb/s transfer rates.

I just setup my new 12 port 3ware 9500S-12 RAID card and seeded it with 3 WD 1Tb drives in RAID5. 3 drives to supplant an 8 drive array (250gig drives) and room to grow. With 3ware's online array expansion and xfs on a linux box, I'm setup to expand this all the way to 11Tb of storage as the price of drives comes down.
I chose WD's new "green" drives over my favorite Seagate for 3 reasons: power, heat, and noise. WD's drives are quiet, cool, and draw 1/2 the power. Sure, they're a bit slower and have a 3year warranty vs a 5 year one, but I'll deal with it.
Oh, and moves, yeah, they're instantaneous ;D
