    Yep, but Lightroom is an inefficient dog at the best of times, so I'm giving it lots of elbow room.

    The easy way to tell is to just check the total system memory utilization in Task Manager, on the "Performance" tab. If you are approaching using all of your RAM then you could benefit from having some more. (Windows will start paging stuff out to disk so it often will not appear that you are using *all* of your RAM.) If you are not bumping up near the limit, then there's not really much point.

    I understand that. But I'd rather put my focus into being productive with my endless to-do list than watching the Performance tab. :-D

    Anyone have a take on this new dock versus the TB18DC? I'm thinking of getting a second dock for a second location where I'll be frequently working.

    Hm, directly comparing both, I would go with the TB18DC for the 7x30. It is connected via Thunderbolt against USB 3.1 (40Gb/s vs 10GB/s) and therefor has more room for extensions and for instant more USB connectors. Also I must admit that the new one looks a little more compact...

    That's exactly the reason why I wouldn't go for the TB18DC. In my experience, USB3.1 docks are quite reliable and solid, while the I'm yet to see a thunderbolt dock that doesn't have issues.
    We're nearly a year after release of the TB18DC, and yesterday I got a bluescreen after unplugging a USB drive from the dock. Once every few weeks, I'll get a bluescreen about the graphics adapter crashing. Those are issues I never experienced when I was using a WD15 on the very same laptop.

    I can only assume Dell believes this too; why else would they release a dock so similar at the same price?

    I agree. While the TB18DC would "technically" be better (higher bandwidth, extra Thunderbolt port on the dock itself), the reality is that Thunderbolt docks tend to be more flaky than USB docks.
    That said, I haven't tried out the WD19DC yet, though I am very interested in doing so. I don't think that I'll be able to get the office to spring for one until around the end of the year. Like @Regular_Ragnor, I have previously used a WD15 dock and it had zero issues. I've also been through TB15, TB16, and TB18DC and those have all come with problems. USB stuff not connecting right, or having it BSOD when I unplug it, or having it not work after I disconnect it and reconnect it (device manager throwing an error until I reboot)... Not all of the time, but often enough that I get annoyed.

    It doesn't look like this new one is any less capable than the TB18DC, other than the lack of a Thunderbolt port. 10 Gbps is plenty to handle all of the built-in USB devices (network, audio) plus a number of extra things you might want to plug in, and the display bandwidth should be separated onto a DisplayPort connection (USB-C can run both over the same cable). I would like to get confirmation that it supports 2x 4K monitors at 60 Hz. (It does confirm 1x 5K at 60Hz on the specs sheet, and 2x 4K is only a little more bandwidth than that.)

    Thanks for your takes on the docks. It's a little consolation that I'm not the only one with a flaky TB18DC... but not much. Given how expensive the TB18DC is, if I don't see them going on sale, I'll be looking at third-party options.

    Aside from Dell, any good sources for another power adapter for my 7730? My experience buying power adapters from eBay vendors has been spotty.

    You can also look on Amazon. My extra ones all came from eBay. Remember that prior generation 240W adapters work fine, and are probably cheaper, so just search for PA-9E. The older adapters are a little bit larger, but if they are stationary then that is not a big deal, and I actually prefer them somewhat because the cord is a bit longer. (At least that is the case when comparing old vs new 180W adapters on my 7530.)

    Excellent. Thanks for pointing that out.
