Fantastic

Pros: Does a great job. Got it for the 5Ghz support and have had flawless performance. When I had it a good 50+ feet from my rt-n56u router, I would get 250-300 Mbps connection speeds. Being USB worried me, but I never saw that being a choke point. Also, worked out of the box with Ubuntu 12.04.
Cons: USB extension cable is short
Overall Review: I put the adapter on a six foot extension and mounted it on the wall to get clear of my system. I think that significantly improved my signal quality.
I really wanted to like this router.

Pros: It worked (mostly) for a year and six days. Wired connections were solid and consistently fast. It looked pretty. It has the neat display on the front.
Cons: The port forwarding configuration is way too convoluted. Wireless connections would drop out on big(ish) transfers. There were times that playing Apple Lossless formatted music from my file server (wired) to my laptop (wireless) would have to re-buffer several times in the same song. Watching 720p mkv files across the network, forget about it. It also didn't seem to handle lots of concurrent connections very well. Torrents would bog it down, even when limiting the upload rate and downloads not being anyway near saturating of my connection.
Overall Review: I finally gave in to my building hatred for this router when I tried to upgrade the firmware to 1.23NA last night. It uploaded the binary, said it was going to reboot and be back in 65 seconds. No big deal. Walked away, came back 5 mins later. The box sat dark. D-Link support got me an RMA, which was great until I realized it was 6 days out of warranty. Since I got to hook up my desktop directly to my cable connection, I decided to do a speed test. It went from 18Mb/s throughput behind the router to 23Mb/s plugged directly into the modem. Um... yeah. I'm replacing my bricked DGL-4500 with a $60 Buffalo router. Sure, I'll lose the gigabit ports, but people say it's pretty solid for reliability. I have a gig switch that will do the job for my wired boxes. One final note, in my experience, if you see "gamer" in the title of any product, it's probably just an over-priced pile of mediocrity, at best.
Insufficient/dirty power

Pros: Nice looking. Keeps drives fairly cool for passive cooling.
Cons: I have two of these and have been having issues with I/O errors and eSATA link resets. It took me months to finally track it down, but I believe the power being supplied to the drive is either inconsistent or insufficient for normal workloads. I have seen issues when using it via USB and via eSATA. This was confirmed when I got the second enclosure a couple of weeks ago and started having problems with it tonight when putting load on the drive.
Overall Review: Ordered a couple of other Rosewill (RX-358 V2 SLV) enclosures to replace these. I have two of those and have had no issues, so I'm just going to run all four drives in identical enclosures.
Stinking fast!

Pros: Fantastic performance and plenty of space for Windows and all my games.
Cons: A little more expensive than the OCZ's, etc of comparable size, but I trust Intel more for reliability.
Overall Review: I came from a RAID10 on a 3ware 9650SE and the performance of this driver blows it out of the water. I'm extremely pleased.
Great on 5Ghz, not so much 2.4Ghz

Pros: Works like a champ on 5Ghz. Solid connections from all over the house. The third party firmware available adds a lot of functionality and allowed me to move BIND/DHCPD from a separate Linux box. Also, I was able to setup my he.net IPv6 tunnel directly on the router.
Cons: 2.4Ghz suffers from high latency and packet loss. It's persisted across multiple versions of the firmware, so I think it's something to do with the radio. It's so bad, I pulled out an old router just to support my 2.4Ghz-only devices
Overall Review: This is the best router I've used feature-wise thanks to the third-party firmware. Thankfully, I was able to work around the 2.4Ghz issues, so that ended up being a minor annoyance for me. If it weren't for that, I would have given it 5 eggs.
Fast enough for a file server

Pros: Very good throughput for a "green" drive.
Cons: Not as fast as a WD Black.
Overall Review: I have two of these setup in a mdadm RAID1 on my home file server, hooked up via eSATA. When the drives were initially synced, I saw transfer rates of 100MB/s (read from one, write to the other). In general use, I get about 40MB/s for non-contiguous reads off of an EXT4 filesystem over NFS. I don't do a whole lot of writing to them directly, so I can't speak to their general write performance. Besides, with them being in RAID1, there would be a slight penalty anyway.
