Samsung SSD 870 QVO 4TB Review

The SSD 870 QVO uses Samsung’s Intelligent TurboWrite technology to boost write speeds by using a portion of the NAND to run in SLC mode as a write buffer. By default the fixed part of this buffer is 6GB but if more is needed the technology allows for, in the case of the 4TB drive, an extra 72GB Intelligent TurboWrite region. The official Sequential write performance figure for the default buffer is up to 530MB/s but out of the buffer, this figure drops to 160MB/s. In our cache test, the performance in the default 6GB buffer averaged 486.92MB/s and 169.45MB/s out of the buffer.
