Currently one of the highest capacity consumer SATA SSD on the market, this SSD offers huge amount of capacity and high R/W which is limited by SATA 3 max bandwidth. However, 4TB SSD and bigger begin to offer lower GB per dollar (which equals lower value) than the lower capacity SSD in the market such as 2TB NVMe SSD (Intel 660p 2TB at $194-209). [Dec '19 ColdSpy]
