means 871

Mixed review for me who had the hard habit DAS (direct connection to the PC). In this config (DAS) throughput is around 150 MB / s performance with Seagate drives. The same disks in the NAS come painfully to 30 MB / s, and this in ideal configuration (connected by ethernet directly on the PC, so of gigabit!).
Connected my Freebox V5 I arrive at better 10MB / s, certe than enough for a broadcast streaming movies or music, but what wound to transfer file to PC or NAS for backups.
Level reliability I took a very big doubt: I transferred all my mp3 and shared over DLNA. After reading many had concerns that made one think of an encoding concern. I listened with several player (Blue Ray, mobile phone, PC). Same problem for all .... This well vients file on the NAS. I listened to the original mp3 on the PC: no problem. I transferred back the file to the NAS and now more of problem.
So that it poses me a big problem because it means copying files from PC to NAS not only took forever, but in addition has not been made correctly. Unacceptable level. Luckily I did not delete the originals.
I wonder what it is that I realize backups on the NAS. Good, hope never to need it ...
Maybe there was a parameter to enable for secure copy, but I do not know. I am not a specialist in NAS. The only thing is that I'm going to set up a file comparison software, The second thing is that I think make this NAS storage means. Ultimately I keep my old e-sata enclosure which remains the storage means, and the NAS will serve him only copy the files to share. The logic was (NAS storage DAS = = Copy)
I took this camera to try a first NAS. I have seen. I think qu'impérativement the following should allow the combined NAS / DAS.
I leave it 3 stars because the construction is good, relatively easy to install, and it should be enough to NAS many users (especially those who want to share media files on a home network).

EDIT April 2013: finally I returned the product to Amazon. I took instead a RNDU2000 (Ultra version) and I must say that there is no picture: speed up to 90 mb / s peak on DIVX [connected to a gigabit switch], much more possible settings, manage multiple volumes ... Furthermore I could retest the file transfer under the same conditions with the Readynas Duo especially with the switch of the Freebox. Conclusion: no copy of error. (I had a doubt: is that errors came from the Freebox or NAS) through against the limited flow again to 10 MB / s So the Freebox limited flow well, but c is the NAS that produced errors [or not the corrigait]. I think that I had a defective product.
For ultra basic usage (broadcast content to a TV for example) the Duo remains a good choice. Make a small test anyway to check that there is no copy error before deleting the original!
