Question (WEIRD) Download speeds for Steam stuttering, not using full gigabyte connection

Hello,
So my Steam downloads are taking forever and keep jumping the speed around like crazy. So far, I have cleared my Steam DL cache, changed DL servers, uncapped DL bandwidth, tested my external SSD for read/write speeds, set the priority of Steam in task manager, and have even gone as far as reinstalling steam. Another issue is that pre-allocating downloads usually takes ~20-30 minutes, so I'm assuming that Steam is having an issue with R/W to my SSD. What makes this problem even weirder is that I have multiple CODs on the same external SSD and through the Blizzard launcher, they will download massive updates at ~60-80 MB/s consistently, while steam usually ends up DLing around 5 MB/s (I have a wired gigabit connection). ALSO, when the download first starts, for about 2 minutes, the download speed will be normal (60-80 MB/s) and then DROP to under 10 MB/s for the remainder of the download, even stopping completely, jumping back to around 30 MB/s, then dropping back down. My SSD is capable of 560 MB/s r/w (TESTED!), and Steam uses just 3-5 MB/s of that as well.
