    Relationship between Cache, Storage Density, Rotational Speed and PMR / SMR

    Seems the SMR drives have inflated cache to compensate for lower performance.

    Cheap SAS (*Right Angle*) SFF-8087 to 4x SATA breakout cable LOTS

    At this price it's worth buying a handful, as long as the lengths (20", 24", 28", & 31") will work with your setup. I personally have 1M cables coiled up and velcro-ed together in one of my short depth cases, so these will work for at least that application. H/T @Rand__ for his post...
