Samsung 990 Pro Price History and Today's Lowest Price

What changed and why

The 990 Pro is Samsung's Gen4 flagship and one of the most widely cross-shopped drives in the market, which makes it a useful bellwether for retail flash pricing generally. It is also one of the drives that moved furthest: as published on 30 September 2026 the 4 TB model was reported at US$994 against a previously recorded low of US$249, roughly four times. That is the shortage in a single line.

Our series begins at our first recorded reading. We do not import a price history from a tracker and present it as our own observation, and we do not estimate backwards. Where a published figure exists for an earlier date it is drawn as its own attributed layer, so you can always tell which numbers we observed and which we are quoting.

A price history page that appears fully formed on the day it launches has been reconstructed from somewhere. Reconstructions are where convenient numbers hide, because nobody can check them. The cost of our approach is that this chart is short at first; the benefit is that every point on it is a price that actually existed when we looked.

How to judge whether today is a good price

A single price tells you very little without a reference. Three are worth having. The first is the per-terabyte figure in the live table above, which lets you compare this drive against every other capacity and model we track rather than against its own past. The second is the published low, shown in the table below, which tells you how far the market has moved rather than how good a deal you are being offered today. The third is the shape of the segment: if every comparable drive sits in a narrow band, there is no deal to wait for.

What rarely helps is comparing against a price you remember. Memory anchors to the best figure you ever saw, which in this market was usually a promotional price from a different supply environment. Judging a 2026 purchase against a 2023 low guarantees disappointment and frequently produces a worse decision than simply buying what the machine needs.

Who it hits, and how hard

1 TB buyers pay the most per terabyte but the least in absolute terms, and this capacity moved least in relative terms because fixed costs cushion it.

2 TB buyers usually find the best balance on this model: enough capacity for a working set plus games, without the premium the 4 TB part now carries.

4 TB buyers took the worst of the increase. If you need 4 TB, compare against the SN850X and the wider 4 TB NVMe field before committing, because the ranking at this capacity has shifted.

Anyone buying for a PS5 should check the heatsink variant rather than the bare drive, and note that the console's requirement is sustained sequential throughput rather than peak, so the flagship is not always necessary.

What to do now

1. Compare the per-terabyte column in the live table rather than the sticker price when choosing a capacity.
2. Check the whole segment on our SSD price per TB page before settling on one model.
3. Convert endurance to a size-independent figure with the DWPD calculator.
4. Estimate real lifespan at your write rate with the lifespan calculator.
5. Read why SSD prices rose before concluding today's price is an anomaly.
6. Check the published forecasts before deciding to wait for a better price.

Outlook

We do not forecast. This page records a reading every six hours and publishes the series as it accumulates. The published forecasts for the wider NAND market are below, each with its date.

We publish no forecast of our own. Everything above is someone else's published position, with the date it was published and a link to it, because a price forecast from a site that sells against those prices is worth nothing to you.
