Hi,
I am trying to install one of these machines, I have put 2 new WD1TB green drives in, plugged it all in, logged on, did all the bits and pieces and away it went. The installed firmware was 1.05, network is 3 macs, 1 PC and gigabyte switches (netgear and belkin).
I want to use the drive to secure and serve itunes and image media to the Macs. I started by transfering iTunes files, all goes well, files transfer at around 17mbs without tinkering with any Jumbo Frame settings.
I then updated the firmware to 1.06.
after the update, file transfers would peak immediately to around 10mbs and then rapidly fall to less than 1mbs, and after a transfer of about 150mb, stop altogether. does anyone have any experience of this or any workarounds.
I have subsequently downgraded the firmware back to 1.05, and had to reformat the drives (they would not mount after the downgrade) and I have my transfer speed back to 15-18mbs. is this an issue with 1.06?
i have a second question about jumbo frames. do all machines have to be jumbo capable, will anything work over gigabit ethernet if some patches are only CAT5 rather than 5e or 6, will jumbo frames make any real difference for a home network serving itunes and image files and maybe the odd movie?
TIA
Nicco

I've been using my DNS-323 on a gigabit switch with both a Mac Mini on that switch as well as a Macbook connecting via 802.11n, and I started with FW 1.04, moved to 1.05 and am now on 1.06, and the file transfers to-and-from the DNS-323, Mini and Macbook have always been quick and stable. Transferring a ~1GB file to the DNS-323 takes a little under a minute.
I, too, have not messed with jumbo frames on the DNS-323, either Mac or the gigabit switch.

thanks for the reply. it does seem odd behaviour, and i am not certain that 1.06 is the problem, the problem stated after the update and nothing i could do would fix it, new locations, cables, switching switches etc, altering software configs, only the downgrade and reformat has fixed it.
any other advice about jumbo frames?

I've been running 1.06 for several months now, but in a pure Windows environment - no issues with stability, or transfer speeds.
As regards jumbo frame, you can run jumbo frame in a mixed environment - what is important is that the network switches that connect the jumbo frame enabled devices support jumbo frame - properly wired CAT5 or CAT5e is fine, for a home LAN CAT6 is overkill - will it make a real difference in a home network, I would say no.
If you're going to be frequently transferring multi-gigabyte files, jumbo frame might be worth it, but for your average mixture of a few Megabytes here and there, you won't see the difference.

very informative thankyou
given the nature of your 'footer', 1.06 makes me nervous now. i have formatted the system in RAID1 for some security/safety. unsure what to do. i think i will pause and use the 'if it aint bust dont fix it' method, stick with 1.05 for a while.
regarding jumbo frames - if i set the dns323 to jumbo 9000 (my switches claim to be compliant), will the computers automatically do what they have to do, and if a machine on the network is not gigabit capable can the dns323 'dumb down' if it is set to jumbo frames enabled?

My 'footer' applies equally to 1.05 as it does to 1.06 - in fact it can be considered universal, in that it applies to every form of RAID (other than RAID0 - which offers no redundancy) regardless of the platform. If you're running a RAID1 array on 1.05, you're as much at risk for data loss as if you were running it on 1.06 - the only way to reduce the risk (notice I did not say eliminate) is to back the data up.
On jumbo frame - no - you'll have to manually configure both "ends" to use jumbo frame, and yes, if only one of the pair supports jumbo frame the other will "dumb down", or to be "politically correct", will automatically negotiate the common MSS (maximum segment size).
