Corsair has launched two new PCIe 4.0 x4 SSDs, the MP600 PRO NH and GS, available for pro and budget-friendly builds. While PCIe5.0 is in its early adoption phase many owners of hardware featuring the previous version may still be looking for storage upgrade options. Both Corsair PCIe 4.0 x4 drives utilize 3D TLC NAND and are in the M.2 2280 form factor, and come with a 5-year warranty. The PRO NH line offers up to 8 TB of storage while the DRAM-less GS line tops at 1 TB. TechPowerUp reports that the GS uses the Phison E21T controller with the PRO NH featuring the Phison E18 conroller.
