Both the Crucial P510 1TB and the Western Digital WD Black SN7100 500GB are M.2 NVMe SSDs that utilize HMB (Host Memory Buffer) as their cache and feature TLC storage type. However, the Crucial P510 offers twice the internal storage with 1000GB, compared to the 500GB of the WD Black SN7100.

In terms of PCIe version, the Crucial P510 supports PCIe 5, while the WD Black SN7100 is limited to PCIe 4. Both products have a 5-year warranty, but the Crucial P510 is rated for a higher Terabytes Written (TBW) of 600, compared to the 300 TBW of the WD Black SN7100. Both drives use four controller channels, though they feature different controllers: the Crucial P510 uses the Phison PS5031-E31T, while the WD Black SN7100 uses the Polaris 3 A101-000172-A1.

Neither drive comes with an integrated heatsink or RGB lighting, but both provide solid durability with a 5-year warranty. The Crucial P510’s larger storage, faster PCIe version, and higher TBW make it a more robust option for users seeking greater longevity and performance potential.

Comparison Summary

This is a specification comparison between Crucial P510 1TB and Western Digital WD Black SN7100 500GB, outlining shared attributes and measurable differences. Both drives use the M2 type, include NVMe SSD support, rely on TLC storage, and come with a 5-year warranty, while lacking integrated heatsinks and RGB lighting. Differences appear in performance and capacity, with a sequential read speed of 11000 MB/s versus 6800 MB/s and sequential write speeds of 9500 MB/s versus 5800 MB/s, alongside varying random read and write IOPS figures. Storage capacity differs at 1000GB vs 500GB, PCI Express versions are PCIe 5 vs PCIe 4, and endurance ratings show 600 TBW vs 300 TBW.
