The Crucial P510 2TB and the Western Digital WD Black SN7100 2TB share many similarities in terms of general specifications, but there are a few key differences to note.

Both drives are M.2 NVMe SSDs with 2000GB of internal storage, use TLC NAND flash, and include an HMB (Host Memory Buffer) cache. The Crucial P510 2TB features PCIe 5.0 support, whereas the Western Digital WD Black SN7100 2TB supports PCIe 4.0, which means the Crucial drive can potentially provide faster data transfer speeds with compatible hardware.

In terms of controller, the Crucial P510 uses the Phison PS5031-E31T, while the Western Digital model uses the Polaris 3 A101-000172-A1 controller. Both drives have 4 controller channels and offer the same Terabytes Written (TBW) rating of 1200, and both come with a 5-year warranty. Neither drive includes an integrated heatsink or RGB lighting, making them both fairly standard in terms of aesthetics and cooling features.

Comparison Summary

This specification comparison outlines shared and differing characteristics between Crucial P510 2TB and Western Digital WD Black SN7100 2TB. Both models use the M2 form factor, operate as NVMe storage, provide 2000GB capacity, and rely on TLC flash memory with HMB Host Memory Buffer, along with identical controller channel counts, endurance ratings, and warranty duration. Key differences appear in performance and platform support, as one model lists PCIe 5 while the other uses PCIe 4, alongside distinct controller designs. Sequential read speeds differ at 10000 MB/s versus 7250 MB/s, and sequential write speeds at 8700 MB/s versus 6900 MB/s. Random read and write speeds also vary between the two configurations.
