Sure, Samsung has the 16 TB SSD drive but that can only run on the server- and workstation-focused SAS interface. The other 4 TB SATA SSD that has been shipping since 2015 was manufactured for data centers and focus on writes speed. they are more expensive and unsuitable for the common consumer. The current 4TB 850 EVO comes in 2.5-inch form factor and is compatible with the SATA interface making it an ideal solution for desktops and laptops with HDD.
The last flagship SSD from Samsung offered only 2 TB of space and by doubling the space, it is entering a new market. It has also increased the write and read speed that is now at 520MBps and 540 MBps. This speed is only limited by the SATA interface that does not support higher speeds.
“The one disappointment in the specifications for the 4TB 850 EVO is the write endurance rating, still the same 300TB total as the 2TB model. A warranty that expires after only 75 drive writes is concerning even if the total bytes written quantity has been reasonable in the past. It can come across as an indication that Samsung lacks confidence in their new V-NAND, which is at odds with the 5-year warranty the drive carries. For comparison, Samsung’s enterprise PM863 based on the older 32-layer TLC V-NAND has a three-year warranty but a 5600 TB endurance rating for its 3.84TB model. Fortunately, it appears that the write endurance rating of the 4TB 850 EVO is very conservative: the testing subjected it to a total of around 7 drive writes but the SMART lifetime indicator is down to only 99% rather than the 90 or 91% implied by the 300 TBW rating.” Quotes Anandtech
This drive is based on the popular V-NAND and the rated write limit is at 300 TB. The price of the device is at a staggering $1500. For comparison, the 2 TB model costs $625 on amazon. But expect the prices to fall down so that SSD will replace HDD for the mass storage solution.
