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.

Western Digital Black SN770 500GB interface, form factor & heatsink compatibility

InterfaceM.2 PCIe 4.0 x4
Form factorM.2-2280
Capacity500 GB
Sequential read / write5000 / 4000 MB/s

DRAM cacheYes
Heatsink includedNo

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 Black SN770 500GB right now?
The price targets at the top of this page are calculation thresholds, not forecasts: they say what the competing offers in the 2026-09-13 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.
Where can I buy the Western Digital Black SN770 500GB?
We track 1 offer(s) across stores, variants and conditions — the first 1 useful price highlights are shown above, which is the complete currently tracked set. Each row keeps its own checked date; always confirm the final price at the retailer.
Is the Western Digital Black SN770 500GB worth it in September 2026?
That depends on your scenario: its Relative Value ranges across presets in the scenario matrix above (currently #130 of 206 in-stock by balanced value in the 2026-09-13 offer frame). Use the live calculator to weigh your own priorities.
Will the Western Digital Black SN770 500GB fit my PC or laptop?
It uses M.2-2280 over M.2 PCIe 4.0 x4. Confirm both the physical slot and interface; an older PCIe slot can cap a newer drive's peak speed, and heatsink versions need extra clearance.
What is the Western Digital Black SN770 500GB best suited for?
It is a 500GB M.2 PCIe 4.0 x4 drive rated for 5000 / 4000 MB/s sequential read/write. The scenario tiers separately grade system-drive responsiveness, game/file storage and heavy write work.
