I wish I were wrong, I'd like to see 50 mbyte/sec transfers to/from my DNS-323!  ;D

I get an average of 6 - 11 MBps trasnfering to my 323. So you in the ball park.

The biggest thing like someone else mentioned. These are not a desktop pc. More compact chipsets , less power.. etc ..

I am in the process of taking everything off my 323 and moving my 2 - 1.5 GB WD Black drives into another cheap computer I just built..
Tired of waiting for the new 1.8 firmware , my PS3 just isn't happy !!

I get transfers in the 18-25 mbyte/sec range to/from my DNS-323 with a pair of Samsung 1.5TB drives installed in RAID-1.  Speeds were faster when I had it running RAID-0, but obviously reliability was not as good. :)

You're the first person I've seen say that RAID-0 was faster than RAID-1 - for most of us RAID-0, RAID-1 and standard disks have all delivered pretty much the same throughput.

RAID1 is for disk redundancy - NOT data backup - don't confuse the two.

I actually was getting faster read speeds when I had a pair of 500gig drives in RAID-0, the write speeds seem similar.  The odd part is, I'd have expected the write speeds to be slower, since there are two writes going on now.

I still can't imagine how people are getting 35-40gbytes/sec from these things in any mode.

I'm hovering around 10 MB/sec to and from my computers Windows 7, to the NAS and all compuetrs/switch is 1GB LAN connection, but they don't have jumbo frames in the NIC properties so I found a computer that does and has a ASUS motherboard with jumobo frames in the NIC properties and from that computer I have done a transfer to the NAS of a 3.5GB ISO image and getting around 14MB/sec, OS is XP Professional, not sure if enabling jumbo frames made it 4 MB/sec faster or XP Pro did, but that's the difference with jumbo frames enabled.
My NAS is RAID-1 anyway.
Still getting around 35 - 45MB/sec from computer to computer.
Just my 2 cents worth
