Value and price targets for every scenario (detailed table)
| Scenario (preset) | Relative Value | Strong Value at ≤ | Excellent Value at ≤ | Market-leading Value (100) at ≤ | Top value pick here |
|---|---|---|---|---|---|
| Balanced | 67 | CAD 479 | CAD 405 | CAD 348 | Western Digital SN8100 2TB |
| System Drive | 16 | CAD 24 | CAD 19 | CAD 16 | Western Digital SN8100 2TB |

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.
Silicon Power UD90 4TB interface, form factor & heatsink compatibility
| Interface | M.2 PCIe 4.0 x4 |
| Form factor | M.2-2280 |
| Capacity | 4 TB |
| Sequential read / write | 5000 / 3200 MB/s |
| Endurance | 2400 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.

Chosen for Game & File Storage, not for general performance — a product that suits a different job is not an alternative here. Tiers come from the same rubric as the tier list; products we can't grade for this job are left out rather than guessed at. Prices use the page's dated offer frame.
FAQ
- What is a good price for the Silicon Power UD90 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 2026-09-13 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.

- We track 2 offer(s) across stores, variants and conditions — the first 1 useful price highlights are shown above, with the other 1 in the additional-offers disclosure. Each row keeps its own checked date; always confirm the final price at the retailer.
- Is the Silicon Power UD90 4TB worth it in September 2026?
- That depends on your scenario: its Relative Value ranges across presets in the scenario matrix above (currently #39 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 Silicon Power UD90 4TB 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 Silicon Power UD90 4TB best suited for?
- It is a 4TB M.2 PCIe 4.0 x4 drive rated for 5000 / 3200 MB/s sequential read/write. The scenario tiers separately grade system-drive responsiveness, game/file storage and heavy write work.
