These new SSDs naturally borrow SanDisk 15nm TLC flash but drive that flash with aftermarket controllers. The Blue employs a Marvell 88SS1074 controller while the Green will use a Silicon Motion SM2256S. The Blue will have the typical SATA 6Gbps saturating specs seen in modern SSDs, while the Green will be derated a bit.

They got rid of the green for HDs, made them all blue, yet, they bring back green for SSDs that will be slow?
Sigh.
