Relative Value is the 0–100 benefit/cost result computed within the current in-stock frame for each preset; the frame leader is 100 and other products show their relative share. Target prices are calculation thresholds under today's dataset; where none exist, the row says so instead of showing blanks. Recalculated on every data refresh.

Prices are the cheapest total (item plus shipping) we recorded for a New, in-stock offer on that day. Value and rank here are measured against products on sale now — 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 Blue SN5100 4TB interface, form factor & heatsink compatibility
| Interface | M.2 PCIe 4.0 x4 |
| Form factor | M.2-2280 |
| Capacity | 4 TB |
| Sequential read / write | 6900 / 6700 MB/s |
| Endurance | 1200 TBW |
| DRAM cache | Yes |
| Heatsink included | No |
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.

FAQ
- What is a good price for the Western Digital Blue SN5100 4TB right now?
- The price targets at the top of this page are calculation thresholds, not forecasts: they say what the competing offers in the 2026-08-25 frame would have to be beaten by under the balanced weighting. Two caveats worth knowing — they move when the rest of the market moves, even if this product's own price doesn't; and hitting a target says the PRICE is good, not that the product suits your job (that's what the tier badges above answer). Change the weighting in the calculator and the targets change with it.
