The drive uses the compact M.2 form factor with a PCI-Express x2 connection to the rest of the system. This is in contrast to the majority of M.2 NVMe drives which use a x4 connection for twice the theoretical throughput. As we'll see later in our testing, this only matters for write speeds. Another cost-optimization is the lack of a dedicated DRAM chip. On SSDs, the DRAM chip typically stores the mapping tables for the SSD to know where its data is located. Of course, the cost saving comes with a performance hit, but pricing matters a lot in this market segment.
The MP32 is available in capacities of 128 GB ($50), 256 GB ($70), 512 GB ($120), and 1 TB ($260). It is powered by a Phison E8 controller and uses Toshiba TLC flash chips. Endurance is rated at 100 TB, 200 TB, 400 TB, and 800 TB respectively.
