Reliable, meh. I've had two die on me. One lasted a few years of VERY light usage, the other died barely a year or two in. Also almost no usage. In both cases it simply stopped appearing on the bus, but was clearly "running" to some degree - it would get warm to the touch, just as they normally do. I've also found that the Thunderbolt connector's lack of a "click" engagement to be a serious issue for storage, network, and even display - every Mac I've seen it in use, the connection has been flaky. It really fucking sucks to whip out the thunderbolt adapter and plug into ethernet for "reliability", set up a transfer of a ton of data, and half-way though shift the machine slightly aaaaaaaaand then the ethernet adapter disappears and your transfer is fucked. Happy to see them drop that idiotic connector for USB-C, as at least that has some sort of physical retention mechanism other than "hopes and dreams" (ie: rely on proper clearance tolerances between different vendors, on surfaces that will wear with use.)
