SPATIUM M390 250GB NVMe SSD

The MSI SPATIUM M390 is a 250GB internal solid-state drive built for consumer desktops and laptops. It uses an M.2 2280 form factor with 3D NAND flash memory and a PHISON E15T controller. The drive targets everyday computing, gaming loads, and content workflows that need responsive NVMe storage.

PCIe Gen3 x4 interface limits

This drive connects through a PCIe Gen3 x4 link using the NVMe 1.4 protocol. The interface caps theoretical throughput, so sequential speeds cannot exceed the bus limit regardless of controller capability. Random read reaches 150,000 IOPS and random write reaches 300,000 IOPS within that constraint. Active power draw is 3.2W while idle consumption sits at 30 mW.

150TB endurance rating

The terabytes-written figure of 150TB defines how much data can be written before the warranty endurance threshold is met. That number determines whether the drive suits light desktop use or heavier write workloads such as video editing caches. MTBF is rated at 1,500,000 hours and the drive includes LDPC ECC, end-to-end data path protection, TRIM, and SMART monitoring.

Questions about this item

Is the 250 GB M390 the right capacity for a boot drive plus a few games?

The 250 GB model holds the OS, core apps and a handful of large titles while leaving headroom for updates; its 150 TBW rating covers typical daily writes for years.

How fast will the 3300 MB/s sequential read actually feel when Windows boots or a game level loads?

Large sequential transfers such as game assets or OS images move at up to 3300 MB/s, cutting load screens to a fraction of what a mechanical drive delivers.

What does PCIe Gen3 x4 NVMe 1.4 cap at for this drive?

The four-lane Gen3 link limits peak throughput to the stated 3300 MB/s read and 1200 MB/s write, so the controller cannot exceed those ceilings.
