"At £379.99 for the 960GB version, £167.99 for the 480GB version and around £760 for the 2TB version these drives are certainly not the cheapest SSDs on the market, though they do offer some of the best performance that is possible on SATA today. "
This drive is designed to be a competitor to the Samsung 850 Pro with similar pricing, with the Samsung drive having the advantage of faster 3D V-NAND and this Corsair Drive using more chips of traditional planar NAND.
Corsair has made some smart decisions when it comes to this drive's firmware and controller setup, though given the limitations of SATA etc both the 850 Pro and the Corsair Neutron Xti will perform very similarly during day to day use.
Price to performance wise it is hard to beat the Samsung 850 Evo right now, and Intel's 600p NVMe M.3 drive is looking really nice ATM.
