Value and rank here are measured against products whose record is under review — the set this product actually competes in — so they will not match a Value Score computed over the whole catalogue elsewhere on this page. A previous-generation part is ranked among previous-generation parts, because that is the choice a buyer of one is actually making.
Western Digital WD_Black SN850X 4TB interface, form factor & heatsink compatibility
| Interface | M.2 PCIe 4.0 x4 |
| Form factor | M.2-2280 |
| Capacity | 4 TB |
| Sequential read / write | 7300 / 6600 MB/s |
| Endurance | 2400 TBW |
| DRAM cache | Yes |

Confirm the physical M.2/SATA form factor and interface your motherboard or laptop accepts. A newer PCIe drive can usually negotiate down to an older PCIe link, but its peak speed will be limited by that slot; check heatsink clearance before buying a heatsink model.
