Big things can come in small packages. According to Computerworld, Samsung has released the world's first 2 TB consumer SSDs:

Samsung today announced what it is calling the first multi-terabyte consumer solid-state drive (SSD), which will offer 2TB of capacity in a 2.5-in. form factor for laptops and desktops.

[...] The 850 Pro is designed for power users and client PCs that may need higher performance with up to 550MBps sequential read and 520MBps sequential write rates and up to 100,000 random I/Os per second (IOPS). The 850 EVO SSD has slightly lower performance with 540MBps and 520MBps sequential read/write rates and up to 90,000 random IOPS.

The 2TB model of the 850 Pro will retail for $999.99 and the 850 EVO will sell for $799.99.

The 1TB EVO SSD will retail for $399; the 500GB for $179; the 250GB for $99 and the 120GB for $69. The 1TB 850 Pro will retail for $499; the 512GB model for $259; the 256GB model for $144.99 and the 128GB model for $99.

[...] Samsung guarantees the 2TB 850 Pro for 10 years or 300 terabytes written (TBW), and the 2TB 850 EVO for five years or 150 TBW.

To put that in perspective, there are approximately 7 billion people on earth. One of these drives has sufficient space to keep about 285 bytes of information on every single person on the planet! Put another way, that is over 6 KB for every single person in the USA.

    "every mlc SSD uses some form of data randomization. Encryption is a common way to achieve that."

    Encryption is not a common way to achieve that; it's an expensive way. The paper you cited (link provided by the helpful AC) talks of an 8-bit pseudorandom generator, presumably with a period of 255. A decent encryption (AES) will require vastly more silicon to deal with 500 MB/s throughput.

    No on-die aes hardware acceleration has been common for many years now on pretty much all the major ssd controllers.

    He's a link to a roundup of various ssds and their implementation status. This link is several years old. It has only improved since then.
