The cables came with the SuperMicro board so I certainly hope they haven't started cheapening out on those :D In any case, the cables shouldn't be the problem because I swapped other drives (SSD and HSGT HDD) into the same drive bay, swapped cables as well as put the Red into 3 different drive bays/SATA cables/ports without any improvement. Both the SSDs I tried were able to hit around 450Mbps sequential write speed which is around the general ballpark performance from online sites so that should eliminate cabling/connection as the source.
