If you think that this performance is a little weak, remember that most 100mb NAS devices can only manage 7-8MB/sec. The processor in the DNS-323 must have to work harder managing the RAID 0 array. The drive manages to read up to 3.6MB/sec faster on the mirror. Oddly enough the performance on a RAID 1 Mirror is slightly higher than the RAID 0 performance. This shows that the drives are not the bottleneck – rather the network overhead on the processor in the DNS-323 is what is holding things back. Next, we ran the same test on a RAID 1 Mirror and found the results to be very similar to the RAID 0 results. It managed to read and write over 20MB/sec sustained – at least in this test. This should yield the faster performance possible and the enclosure did quite well. The first test shows data transfer onto a pair of striped drives on a GB network. Next, we fired up the popular ATTO benchmark to see how small file and large file transfers affect performance. If we could sustain 43MB/sec on a network attached storage device, it would be darn incredible. In reality, we expect to see much lower performance than what SiSoft reports. The performance numbers look promising as we were able to reach 43MB/sec. To find out how fast the DNS-323 could be on our network, we first fired up SiSoft Sandra to see how fast we could transfer “simulated” data to the DNS-323.
