Relative Value is the 0โ€“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 โ€” the set this product actually competes in โ€” 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 SN770M 1TB interface, form factor & heatsink compatibility

InterfaceM.2 PCIe 4.0 x4
Form factorM.2-2230
Capacity1 TB
Sequential read / write5150 / 4850 MB/s
Endurance600 TBW
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 SN770M 1TB right now?
The price targets at the top of this page are calculation thresholds, not forecasts: they say what the competing offers in the 2026-09-11 frame would have to be beaten by under the balanced weighting. Two caveats worth knowing โ€” 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 SN770M 1TB?
We track 2 offer(s) across stores, variants and conditions โ€” the first 2 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 SN770M 1TB worth it in September 2026?
That depends on your scenario: its Relative Value ranges across presets in the scenario matrix above (currently #121 of 378 in-stock by balanced value in the 2026-09-11 offer frame). Use the live calculator to weigh your own priorities.
Will the Western Digital SN770M 1TB fit my PC or laptop?
It uses M.2-2230 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 SN770M 1TB best suited for?
It is a 1TB M.2 PCIe 4.0 x4 drive rated for 5150 / 4850 MB/s sequential read/write. The scenario tiers separately grade system-drive responsiveness, game/file storage and heavy write work.
