Tracked days counts distinct days on which a price was recorded for that product, so a median of 200 means a typical product in that segment carries roughly 200 recorded days of history.

Prices are what a consumer pays at retail in the United States, recorded from Amazon (history, licensed from Keepa) and Newegg (current prices, via the retailer's catalog feed). This is a different series from the contract and spot prices quoted in industry reporting, and it follows those with a lag of weeks.

Amazon prices are recorded six times a day. The full definitions, calculations, and limitations are on the methodology page, including what this data cannot tell you. That page is worth a skim before citing a figure.

Current findings

Figures below are computed from tracked prices and update automatically. Each is stated as a magnitude rather than to a decimal place, because comparisons over longer windows rest on smaller product sets and can shift as the catalog changes. The exact current numbers are on the price index.

How to cite

Please include the date the figure was computed, which appears on every page carrying data. Figures change daily.

Custom data requests

Most of what is useful for a story is not on the site. If you tell us what you are writing about, we can usually produce it the same day at no cost. Examples of what has been asked for or is readily available:

We do not charge for this and do not ask for anything in return beyond attribution. Write to [email protected] with the question you are trying to answer and a deadline if you have one.

What we can and cannot speak to

Worth stating plainly so you know whether to call.

We can speak to: what consumer retail prices have actually done over the period we cover, how specific products and segments have moved, how current prices compare with their own history, and how our figures are calculated.

We cannot speak to: contract or spot pricing, manufacturer production decisions, supply forecasts, or anything about the memory industry's internals. Those are TrendForce's and the manufacturers' territory, and we would be guessing.

We are a single-person project with a licensed data source, not a research firm. That is worth knowing before you describe us in print.

About the source

MemRadar is an independent price tracker built and run by Malcolm Konner. It is funded by affiliate commissions from retailer links, disclosed on every page that carries them, and those commissions do not influence prices, rankings, or the figures published here. The full disclosure is on the affiliate disclosure page.

The site's data and methodology are public because a number nobody can check is a number nobody should print.

Figures on this page update automatically from tracked prices. Page last regenerated: September 15, 2026.
