Hi,
What are the exact benefits/drawbacks in using either ext2 or ext3 specifically with the DNS-343?
"Best performance/Most stable" does not really contain enough details to make an informed decision.
I am aware of the differences between the two file systems in terms of journalling/etc, but what level of testing has been placed on using the two different filesystems with the DNS-343?
The ext3 filesystem seems to be a new addition to the DLink DNS series.

I would like to know as well. I have setup my DNS-343 with the ext3 file system. With 4 Seagate 1TB drives. I have been trying to copy about 700 GB of data for days now. I first tried using the download utility of the 343 and it did not copy all the data and stopped transferring. I lost power at the house and then tried to do a incremental backup and it was not progressing. So now I am trying to push the data using Allways Sync and that is taking forever. I know that there are a lot of variables.
But I am noticing some hiccups with the 343. Like the front displays stating an IP of 192.168.0.32 when the easylink utility shows a IP of 192.168.0.106 and I can connect to the drive using the same IP. Powered down and it then read correct IP.
I wanted to test the RAID so I powered down and pulled a drive. I had setup the 343 to email me when a drive failed. Powered the unit back up and it did not send an email. Reported that the RAID was degraded. I then sent test email from the unit and it sent just fine. I put the drive back in and it states that it is in the process of doing a 774 minute sync. That is 12.88 hours. A long time in my opinion. But, I am new to these units and want to make sure that my data is safe.
Sorry I do not mean to hijack this thread. If it needs to be moved please let me know.
Thanks,

I am not the mod here, but I would start a new thread if you want your non filesystem question points addressed.
The reason I didn't answer this before is because I didn't quite understand the original posters confusion, so I will spell it out for everyone since I guess I was the confused one.
EXT3 is EXT2 with a journal
a journal allows quicker (and more reliable) filesystem recovery in case of a unexpected unmount (like losing power).
Thats it!
My personal recommendation is that everyone use EXT3 every time for every job. The performance cost of writing a journal is unnoticed in a network appliance such as this, and HDs are not as access sensitive as say flash where you would want to avoid the extraneous reads and writes.

Thanks, that is a little clearer. I will post the rest in a new thread.
