Capacity and interface

The Corsair MP600 CORE XT is a 4TB internal solid state drive built for consumer desktops and notebooks. It uses the M.2 2280 form factor and connects through a PCI-Express 4.0 x4 link with NVMe 1.4 protocol. The Phison PS2021-E21T controller manages 3D QLC memory to deliver up to 5000 MBps sequential read and 4400 MBps sequential write speeds. AES 256-bit encryption is included for data security.

Motherboard slot and protocol

Verify that your system provides an M.2 slot wired for PCI-Express 4.0 x4 and that the BIOS supports NVMe 1.4 boot devices. The drive draws up to 5.1 W during active writes, so confirm the motherboard can supply that power envelope. No separate cable or bracket is required; the module installs directly into the slot. Check the motherboard manual for any shared-lane limitations that could reduce bandwidth.

Thermals noise and power

In normal operation the SSD idles below 5 mW and consumes 5.0 W during active reads or 5.1 W during active writes. With no moving parts it produces no audible noise. The controller is rated for 1500000 hours MTBF and sustains up to 600000 random read IOPS and 1000000 random write IOPS. Adequate case airflow or a motherboard heatsink helps maintain consistent performance under sustained workloads.

Questions about this item

Does the Corsair MP600 CORE XT 4TB come with a heatsink or mounting screw, or must they be purchased separately?

The drive is supplied as a bare M.2 2280 module; a heatsink and motherboard mounting screw are not included and must be sourced separately if your system requires them.

Should I choose the 4TB 3D QLC model or a smaller capacity for a PCIe 4.0 laptop upgrade?

The 4TB 3D QLC version delivers up to 5000 MBps read and 4400 MBps write on PCIe 4.0 x4, giving the highest capacity and speed in the MP600 CORE XT line for compatible laptops.

What does the 5000 MBps sequential read figure mean when the drive is installed in a real PC?

It represents the peak throughput the Phison PS2021-E21T controller can sustain over the PCIe 4.0 x4 link during large-file transfers; actual speeds depend on workload, thermal conditions and the host system's PCIe implementation.
