In short I suspect the drive is faulty as off signing into windows the drive is at 100% usage and just sits at 100% usage with latency from that drive getting worse to the point where the system is freezing up on the most basic tasks and I have to force shutdown the PC to just be able to use it. I do intend to replace all my drives soon. Strangely on the rare occasion it isn't bottlenecking my whole PC it gets good read/write speed of around 1Gbps - 1.5Gbps
