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.

    The purpose is probably to boost block size. So changing a single bit in a file (Capitalizing something?) will result in many bits of the file changing so they use up the limited writes faster and get to sell another sooner.

    Please refrain from proclaiming on topics you are ignorant of. Like all disks implementing AES full-disk encryption they use CBC (chained-block-cipher) mode which breaks the data-stream up into discrete blocks sized to matched the size of the SSD's block-size. Any other configuration would absolutely kill performance - having to write multiple blocks for a single bit change.
