Prime Big Deal Days runs October 6-7, 2026, with new deals dropping at 12:01 a.m., 8 a.m. and 1 p.m. PT each day. We measure every price against that item's OWN recorded history, not against a list price - the June 2026 event moved our tracked category prices almost not at all, even where headline deals were real. The event has not started yet.

Every retailer's own deal badge, and most deals coverage, measures a discount against the list price Amazon or the manufacturer displays. That number has been documented as unreliable this year specifically: PCMag's own June 24, 2026 Prime Day SSD coverage states, about its own featured deal, that βsome SSD makers have jacked up their SSDs' list prices this year, so the discounts are all relative.β A 60%-off badge sitting on a list price raised weeks earlier is not evidence the current price is actually low.
So we do not use it. Every price on this page and everywhere else on this site is measured against that specific item's OWN recorded price history - the lowest we have ever tracked for it, and how today compares. That is what a verdict badge means: AT/NEAR LOW, TYPICAL, ELEVATED, or NEW while we build the history to say more.
We tested whether this distinction actually matters using June 2026's Prime Day, the most recent comparable event, and it did: our measured retrospective found the matched-model index for every category we could track stayed within about one percent of flat across the event days, and the share of items at their own recorded low was statistically identical to an ordinary week - not higher. Individually reported deals were real. The broader market we track barely moved. Both things were true at once, and a percent-off-list figure could not have told you that.
We measure every price against that item's OWN recorded history, not against a list price - list prices get raised before a sale, which is documented and cited on this site's event pages. A verdict badge means: AT/NEAR LOW is close to the lowest we have ever tracked for that item; TYPICAL is ordinary for it; ELEVATED is above where it usually sits; NEW means we have not tracked it long enough to say. No percentage-off-list figure appears anywhere on this site as a measure of whether a price is actually good.
Before this event, we ran the same test on June 2026 Prime Day using our own daily price history rather than trusting anyone's headline. The short version: the honest finding is in the retrospective - most tracked storage categories barely moved, even in the same window some genuinely low individual deals were reported. We will grade this event's outlook the same way once it has happened.
Live picks below, ranked cheapest first, each with a verdict badge comparing it to its own tracked history - not to any list price.
Desktop and laptop M.2 drives, isolated from enterprise U.2/SAS SSDs by form factor. All tracked NVMe/SSD listings.
The full external drive hub compares every tracked model.
107 in-stock cards tracked across 8 established brands. Full microSD hub, including the speed-mark decoder and the counterfeit price-floor check.
Full PS5 SSD hub, including heatsink pairing.
Full NAS device hub. Buying a discounted diskless NAS? Size the drives to go in it with the fill-basket calculator, which prices a complete build rather than the empty chassis alone.

Tracking since 2026-09-22 - every kit below reads TRACKING/NEW rather than a verdict, because we do not yet hold enough history to say whether today's price is low for it. That is the honest state, not a missing feature. Cheapest right now: $4.43/GB. Full RAM section.
Buy the capacity you need now, do not buy speculatively, and a working kit you are happy with is not a reason to buy. Part of this market's demand is fear of higher prices, and buying on fear is how a buyer ends up owning capacity they did not need at the top of a price cycle. If your machine works and the memory in it is enough for what you run, the right amount to buy today is none.
The same caution applies across this whole event, not just RAM: a sale date on the calendar is not itself a reason to buy. Check the verdict badge on the specific item, not the banner at the top of the page.
Enterprise-class new drives and the refurbished/recertified market run on a different pricing rhythm than consumer retail promotions, and neither moves much for a two-day Prime event. The real, ongoing saving in this part of the catalogue is the recertified-versus-new spread we track year-round, not a seasonal discount.
Right now, matched model-for-model - the same drive priced new against itself priced recertified, averaged across 12 qualifying capacities with at least three models each - recertified enterprise drives run about 34.1% cheaper than new. That is not a Prime Day number; it is the standing state of the market, computed live, and it is usually a bigger saving than anything a two-day sale produces on new enterprise stock.
If your workload can accept recertified or refurbished stock, that is where to look for a real discount this week and every week, not the Prime Day banner.
Shucking - buying an external drive for the bare drive inside it and discarding the enclosure - only makes sense when the external is genuinely cheaper per terabyte than buying the same capacity bare, new-for-new. Right now the best matched capacity we track is 24TB, where the external runs about 27% cheaper per terabyte than the cheapest new bare drive at that size. The comparison changes by capacity and by week, so check it live rather than assuming last year's rule still holds: the full shucking guide has every tracked capacity, matched new-for-new.
October 6-7, 2026, starting at 12:01 a.m. Pacific time on October 6 and running 48 hours. Announced by Amazon on September 14-15, 2026.
Amazon's own announcement states new deals launch three times a day during the event: 12:01 a.m., 8 a.m. and 1 p.m. Pacific time. The status banner above shows the next scheduled drop once the event is live.
We measured this directly rather than assuming it, using our own June 2026 Prime Day data: matched-model index changes across NAS HDD, enterprise HDD, SSD and external HDD stayed within about one percent of flat during the event, and the share of items at their own recorded low was statistically the same as an ordinary week. Individual headline deals can still be genuine - one PCMag deal we checked was a real $639.99 price on a WD Black SN850X 4TB - while the broader category barely moves. Read the full measurement in our June Prime Day retrospective.
That depends on the category, not the calendar. Check the verdict badge on the specific item you want in both events rather than assuming one event is categorically better - our Black Friday storage deals page uses the same live-data approach for that event, and enterprise and refurbished drives rarely move much for either sale (see the section below).
Yes, per Amazon's own terms: Prime Big Deal Days deals are exclusive to Prime members. A free trial is available through Amazon directly if you are not already a member; we do not sell or administer Prime membership.
Not on its own. List prices in storage have been documented as raised ahead of sales this year - PCMag's own June 2026 Prime Day coverage states plainly that some SSD makers had inflated list prices before the event. We measure against each item's own recorded price history instead, which a raised list price cannot distort.
AT/NEAR LOW means a price is close to the lowest we have ever tracked for that specific item. TYPICAL means it is ordinary for that item. ELEVATED means it is above where it usually sits. NEW/TRACKING means we have not held enough history to say yet - every consumer RAM kit on this page reads that way, because our RAM tracking started September 22, 2026.
