There are high failure rates for the 4TB version of this drive. After moderate use the drive can develop bad sectors which block file reads. Scandisk does not detect the errors and the data blocks are not recoverable. There are widespread reports of this problem but Samsung have yet to issue a statement. [Jul '23 SSDrivePro]

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]
