SanDisk Ultra 3D 4 TB 2.5" SSD @ TechPowerUp
 

The SanDisk Ultra 3D is the most affordable 4 TB SSD available, currently selling for only $390. In terms of performance, it's nearly as fast as other high-end 2.5" SATA drives, and write speeds are sustained very well since there's no TLC write hole.
