The highest capacity M.2 SSD that's currently in the market. Offering 4TB of storage space in a such small form factor while using NVMe interface, this SSD is ideal for mobile workstations, or users who have only one M.2 slot left in their motherboard or wants to maximize total storage capacity without resorting to 2.5 inch SATA SSD or in worst case, HDD. The only downside is pricing which is expected for SSD that has 4TB of storage and has very fast NVMe interface while using M.2 form factor. [Jun '20 ColdSpy]
