I guess so, if you're on a budget. The MiniStation was $160 from Amazon, including shipping (I'm a Prime customer) and the miniSwap/U3 was $110 with shipping. But with the MiniStation I also got a 500 GB HDD, which I'm going to use, somewhat ironically, in the miniSwap/U3 because it supports hot-swapping and has that swinging door access. Considering that I paid $230 for each of the 840 Pro's that went into the enclosures, and that I now have a spare 500GB drive, the price difference is pretty minuscule.Apart from the price-tag, lol ^^
I personally think that the biggest consideration is whether you want TRIM support or a potentially greater ability to use the drive with more computers. Since the only USB 3.0 capable computer that I use also has Thunderbolt, it's a pretty easy decision for me, but if USB 3.0 was more prevalent in my circle I *might* lean toward it - but TRIM support, at least for me, is pretty significant. Oh, the MiniStation comes with a Thunderbolt (and USB 3.0) cable, in case anyone was wondering. Whichever way you go, they are blazingly fast - it's good either way!
