Summary: I was a little disappointed with my read/write speeds until I did a little research. Removing unused protocols and enabling jumbo frames on my adapter (not the NAS, but on my network adapter) yielded nice results.
Pros: You can't beat this NAS at the ~$100 price range. You will have to spend at least 50% more to get better read/write performance. I get write speeds in the 70-75mb/s range consistently, and read speeds in the 80's-90's, in Raid 0.
Summary: I bought this mainly to move streaming from my laptop to TV, and keep my laptop out of that loop. I wasn't too crazy about working my disks like that for very long. This box and software does exactly as the documentation states. And nowadays, to buy something brand new, get it home and it is not broke or faulty, you have done something remarkable. I have bought far too many things made in Asia that are not what the advertisement says they are, and are total junk.
Pros: - Fast, easy setup right out of the box - Product does exactly what is advertised (so far)
NSA320 is the best price/performance NAS I could find

Summary: First, the most important piece of info - After being slightly disappointed with write speeds in the high 30's, I started researching tweaks and found two very fruitful suggestions: Go into your computer's network adapter settings, and 1) Turn off the protocols that you aren't using (in my case, IPv6 and QoS packet scheduler and others), and 2) Enable jumbo frames on your NIC (mine was defaulted to disabled, so turning this on for the NAS wasn't enough).
Summary: I bought this right after Christmas as a backup to my primary NAS. I set it up and all worked. A week later I was going to configure it some more and it would not respond. It looks like the NIC stopped working. Tried a few things but no luck. I just wanted another one but they only do refunds, not replacement. So far so good, no hassle but I need another one. Still might give this model another chance but have not decided for sure yet.
Summary: I recently bought one of these refurbished and was very pleased. I then bought a new one for my Accounting firm to back up all our tax files but it showed up DOA. Apparently a whole lot of these have firmware issues that keep them from booting correctly. Watch out.... Buy refurbs, they have the fixed firmware.
Summary: Purchased on December 8 (delivered December 12, 2013), unit failed to complete start-up cycle. Returned and ordered a replacement on December 14 (delivered December 17, 2013) and replacement unit demonstrated same symptom. Returned again and replaced with Synology DiskStation 2-Bay Network Attached Storage (DS213j). Although double the cost, the Synology DS213j product is worth the extra money.
