Samsung recently released a 4TB capacity of their popular Samsung 850 EVO series featuring 48-layer 256Gbit TLC V-NAND. It offers sequential read speed of 540MB/s and a maximum sequential write speed of 520MB/s (or 500MB/s with non-TurboWrite). The Samsung 850 EVO 4TB would be an ideal solution for content creators who work with large file sizes and need the speed of an SSD. It also features 300TB total bytes written and Samsung is offering a 5-year limited warranty. It’s now available to order and comes with a retail price of $1,499.99 (at launch). More details below.

Basically, the new Samsung 850 EVO 4TB is not far from the other capacities except for its capacity and some new components inside. The 4TB capacity features the company’s MHX controller, same controller used by the 2TB capacity. Its NAND flash is a 48-layer 256-bit TLC V-NAND paired with 4GB of LPDDR3 DRAM. Meanwhile, the lower capacities (including the 2TB) use a 32-layer 128Gbit TLC V-NAND. Like the 2TB capacity, it also has a 300TB endurance ranting and features the same security or encryption features like AES-256, TCG Opal and IEEE-1667.
In terms of performance, the Samsung 850 EVO 4TB promises a sequential read speed of up to 540MB/s and a sequential write speed of up 10 520 MB/s when TurboWrite is enabled. It also offers a 98000 IOPS 4KB Random read (QD32) speed and 90000 IOPS 4KB random write (QD32) speed. Based on reviews, the 4TB’s performance is somewhat similar with the 2TB capacity; having a sequential read speed of around 515MB/s and 500MB/s write.
At launch, the retail price of the Samsung 850 EVO 4TB capacity is $1,499.99 which is steep. Meanwhile, street price for the 2TB capacity is around $645; two of the 2TB capacity is cheaper compared to a single 4TB capacity. I expect that pricing for the 4TB capacity will adjust soon, specially when more high capacity SSDs becomes available in the market.
