I have two segate 1TB drives with both filled with content, and formatted with the ext3 FS. The goal was to simply drop these in the enclosure, disable any type of raiding (simply wanting two separate volumes).

Unfortunately upon login, and after selecting single disks (or whatever the first option is with firmware 1.07), the 323 recognized the two physical drives, but didn't report any volumes..

I have since formatted, and manually copied the data back to the BAS (long process as max throughput over 1000mbit seems to be ~9.5 MB/s). I am curious if this type of behavior is intentional, or i simply missed something? Would creating a specific set of folders, cause the smbd on the 323 to reconize the preformatted filesystem?

JS!!!

It's generally a poor practice to try to transplant a drive with data into one of these units.  I suspect many have tried, but few have succeeded.

On the throughput side, you should be able to get 18-20 mbyte/sec transfers if you use gigabit with jumbo frames.

hey thanks for the quick response..

Re: preformatted drives.. Thanks for the tip, when i am not so lazy, i will pop the 323-formatted disks into my desktop box make note of the file structure..

Re: IO performance..

I have now set MTU = 9000 for the gbit interface on the src box, and ensure that the target (323 is enabled for Jf9000) . I am still seeing ~10MB read/write speed, so no major change :<

write..
$ dd if=/dev/zero of=/mnt/media/Video/1GIG.out bs=1G count=1
1+0 records in
1+0 records out
1073741824 bytes (1.1 GB) copied, 101.257 s, 10.6 MB/s


read..
$ time cp 1GIG.out ./

real   1m21.200s


FWIW my gbit setup is all dlink gear ;-)

D-Link System Inc DGE-530T Gigabit Ethernet Adapter <--> DGS1008D gbit switch <--> DNS 323 nas.. I suspect the cpu may be spiking on the NAS during IO tasks, but i am not certain how to access a console yet (still poking around these forums)

I have gigabit all around and I'm using 4k jumbo frames.

For large files, I can read and write in the 16-18 mbyte/sec range.  Some claim much faster speeds, but I've never managed to achieve them.
