MSI Spatium M450 PCIe 4.0 SSD

The Spatium M450 achieves its performance by combining the Phison E19 controller with Micron's most recent 172-layer Micron NAND memory, the NAND is written as TLC, which we certainly appreciate. This is a mid-range NVMe SSD in every way, and that is something we need to acknowledge. As a result, PCIe 4.0 compliance is essentially a label on a box, adding no value to system functioning.

Thanks to the faster PCI 4.0, it is also possible to do without a DRAM buffer (with certain restrictions) by including the normal working memory. The theoretical cost savings are not to be sneezed at, because in addition to the saved components on the PCB, this naturally also becomes simpler and thus cheaper. However, the controller can also be cheaper if you no longer have to use and address the DRAM.
