Offered nearly 1TB of storage and lightning fast 4K R/W speed. The only thing that bog this down is sequential R/W speed which PCIe 4.0 NVMe SSD excels. This SSD is intended for users who need to transfer huge amount of small files without having to deal with low transfer speed but can be used as boot/gaming drive if you wish. Costs more than a thousand dollar which for that price buys you a great 1080p 144hz gaming PC. [Nov '19 ColdSpy]
