Samsung is making another big splash in the storage market this morning. The company is doubling the top-end capacity of its popular 850 EVO SSD to a whopping 4TB using its 48-layer V-NAND flash memory. The sequential speeds of this enormous drive are similar to the rest of the 850 EVO lineup: it's claimed to deliver 540 MB/s read speeds and 520 MB/s write throughput. The drive can perform 98K random read and 90K random write IOPS at QD32, while QD1 IOPS fall to 10K reads and 40K writes.

This largest 850 EVO will only be available in a 2.5" form factor. Samsung warrants the drive for five years or for 300 terabytes written, whichever comes first. The drive carries a hefty price tag to go with its hulking capacity: expect to see a $1,499.99 suggested price when the drive hits store shelves in over 50 countries and regions at launch (including the USA, Europe, China, and Korea).
