I had the first gen Time Capsule, long before I had any Apple products. I made the switch then, because they were one of the first ones to successfully implement remote storage. For seven years, the old unit worked flawlessly, but as our Internet and storage demands grew, it struggled to keep up. I payed almost $300 for the original unit back in 07, which hurt bad, but can't complain about 7 years of good service.
Prior to buying the unit, I was going through routers once every 1 1/2 to 2 years. They would somehow all die sudden deaths. With the non Apple units, I seemed to always be chasing down disconnects, random reboots, incompatibilities, etc., so after three units and three different brands and eventually trying unsuccessfully to add remote storage to my network, I was more than happy to try a Time Capsule.
That was then....fast forward to today and I was once again in the market for a stable, reliable router with solid storage capabilities.
By this time, we had added a few other Apple products to our electronics, but I still need strong Android and Windows compatibilities. I really wanted to go an alternate route this time, so I could have a bit more control over storage, so I looked at every offering out there and Synology seemed to be the only storage unit with rock solid reviews and compatibilities across the various platforms I use. The biggest problem I ran into was the inability to find a router that didn't have a slew of the old issues I used to deal with pre-07! Many had great reviews, but the negatives were all too familiar. Besides, the Synology storage solution was going to be a hefty hit to the finances...I'll still do it at some point.
I read review after review about how the Time Capsule is limited in its configuration and for dummy Fan Boys only and how pricy it is, etc., etc. As a techie, I dig configuration options, but I try to balance that with how much tech support I feel I can stomach, after I've spent the whole day at work doing it.....not much. I also read many reviews about incompatibilities with older Windows systems, so I was a bit leery, but nothing else was floating to the top.
Many have posted the price being too high, but in my research, all AC capable routers are in the sub $200 range, which puts them on par with the Airport Extreme. So, for roughly another $100, I was adding 2T of internal storage, which is as good a price as I can get on the drive alone! I just don't see what the complaints are regarding price. You can't get the same set up for less across any brand. At least, not as of this writing.
Now, for the setup. If you already have a functioning router, you will be asked to provide the SSID and password for the old unit and Voila, everything gets transferred right to the new Time Capsule. It took me all of 5 minutes, including opening the package, making the connections and waiting for it to boot.
It's a bummer the unit doesn't have a USB 3.0 port, but the internal drive is super fast. I timed copying a large movie file to the drive via a wireless N connection and the same move took twice as long to copy to a USB 2.0 drive connected directly to my computer. this limitation isn't going to a huge bummer, as most any remote storage I add will use an Ethernet connection.
I've since connected several Windows 7 and 8.1 systems to it flawlessly, so not sure what others are complaining about with regards to older Windows systems. XP is almost dead, so if that was the complaint, it will soon be a non-issue.
Can't wait to try in wireless AC, but so far the Wireless N side has been flawless and fast. No bottlenecks whatsoever with 10 simultaneous connections. Wow, something that actually works as advertised! What a concept. :-)
