Hello,
I've had a DNS-343 for a little under a year now, and while I've been happy with it's capabilities I've been a little underwhelmed by the performance. That said, I'm not sure that I have a good handle on what I should reasonably expect. Reviews I read prior to purchasing made me think that it would do a little better then what I've been getting.
My home network is based around a single 16 port 3Com GigE unmanaged switch. Cables to the hosts are call Cat 5E or Cat6, pre-made. Jumbo packets are not currently enabled on any hosts.
The NAS is running 1.03, but no funplug or anything. The NAS has 4 1.5GB disks in it, formatted ext2, each disk is running individually. Both my laptop and desktop are Windows 7 x64 machines. The desktop disk is actually one I replaced in the NAS with a larger disk.
I did a test today copying a large file (~4.4GB) around:
| Source | Dest | Time |
| NAS | Laptop | 15m 35s |
| Laptop | NAS | 6m 58s |
| Laptop | Desktop | 2m 6s |
| Desktop | Laptop | 1m 50s |
Is that just what I should expect?
Thank you!
Edit:Not doing JBOD or RAID.

My DNS-343 is configured identically to yours except I'm using 2TB HDDs. A similarly sized file transfer typically takes ~8 minutes (NAS -> PC) and ~11 minutes (PC -> NAS). Network configurations aside, the HDD spin rates will also impact your transfer speeds.

Well 3 of the 4 are 7200 RPM disks. One is a new WD, one of the green ones, but that's not the one I benchmarked. And I know the 3 7200s should be at least as fast as the disk that's in the desktop, but they aren't even close. Anyway, 4MB/sec would be pathetic for a modern disk, if that's all it could manage.
I would understand more if I had a bunch of RAID overhead, but since I'm not doing that I'm a little surprised that it's as slow as it is. It's got me contemplating building a WHS machine or putting a file server together again, which is unfortunate, as I wanted a NAS to get away from running a full blown server, but the slow performance is starting to bother me.

I share you sentiments. I purchased my DNS-343s primarily for the networked storage capacity, with performance as a secondary consideration. The unit serves it's purpose as a means of high capacity storage, but the transfer rates are wanting.

i'm getting about 6 minutes for an 8 gig file transfer.

Few questions:
- What are the HDD(s) manufacturer and model
- When you look at the specs for the HDD(s), what is the cache size
- Are there any jumpers installed on the HDD's to step them down to 1.5 Mbps (some HDD's ship jumpered for 1.5 instead of 3.0)
Cheers,

It depends on your network as well. For example if you are on a 100Mbps network you'll only be able to do somewhere south of 12.5MBps.

I expected more too,
I'm using 8port-linksys G-Ethernet switch on Win7-64bit.
Transfer PC > Raid-0 12MB Ext-3
Transfer Raid-0 > PC 35MB Ext-2
Transfer PC > Raid-5 10MB
Transfer Raid-0 > PC NA
I just changed from 2x 2TB Raid-0 to 4x 2TB Raid-5 and am transfering data back to NAS (I backed up my data to my PC's Raid-0 4TB ( 2x 2TB ).
So Trasfering 3TB of data is more like days not hours.
Anyone know how to get a faster trasfer rate? A Win7 port setting?
New to this, first wanted fast-Big storage but now want safe data (DNS-323 died with Raid-0 2x 1TB, not sure if its the NAS or the Drives yet, need to pull out drives to test).
