Specifications & Features

Introducing the Spatium M450, a PCIe 4.0 solid-state drive with read and write speeds of 3,600 megabytes per second and 3,000 megabytes per second, respectively, from MSI. The maximum random read and write rates are 420,000 and 550,000 operations per second, respectively. The controller in question is a Phison E19T, which has error correction and data protection as standard features. The drive is offered in three different capacities: 250GB, 500GB, and 1TB, with a TBW of 600 times the storage capacity of the drive in each size. It will take five years to reach the specified terabytes unless the limit is surpassed sooner. The average amount of time that passes between failures is around 1.5 million hours. Prices and release dates have not been published at this time.

Phison E19T

The product is powered by a Phison E19T controller, we do not spot DRAM on the SSD, ergo this is based on Host memory buffering (DRAM-less), basically it'll use a small chunk of your system memory. The four-channel Phison E19T memory controller guarantees PCIe 4.0 x4 lane capabilities and compatibility.  The controller has one Cortex R5 core, and is not regarded as a high-end consumer controller. E19T controller supports a maximum of 2TB of data but nevertheless is powerful enough to produce impressive results, pushing data at a rate max of 3.75GB/sec. Little is known about E19T however our colleague website Anandtech has a nice overview table, which we show below, courtesy to them.
