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. This event has ended.
Live prices updated Β· event Oct 6-7, 2026 Β· prices re-checked about once a day
Ran October 6 - October 7. A measured retrospective will follow the same method as our other event reports.
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 price we recorded for that item over the days we tracked it in the last 30 - each badge prints that number of days - in a record where its price has actually moved (a price that has not moved is not a low, and reads TYPICAL); 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.
Is a discount real? We checked every storage item carrying a discount claim against its own price history - how many are at their own low, how many at their usual price, and how many are too new to judge.
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.
Three per group, ranked by price Γ· capacity (dollars per GB or per TB, the Per-unit column) and nothing else. Each badge compares the item with its own tracked history, not with a list price; the condition cell shows who sells it and what Amazon and the seller say about its condition. Every category's full page is listed after this.
Each category has its own page: live verdict-badged picks, what June's Prime Day measured for it (or why it could not be measured), and the buyer trap specific to it.
Buying a whole system? Complete builds prices 7 systems part by part - NAS plus drives, a filled disk shelf, a homelab rack, AI workstation storage - every part badged against its own record, the largest at $7,768 today.
Pages marked with a launch price cover products we hold no price history for yet: each row shows today's price against the maker's own launch price, in dollars, with the maker's document footnoted - a reference a raised list price cannot move - until seven days of our own record let the badge give a verdict.

The top of each category's range, today: the highest tier in stock, its cheapest listing, its price per unit, and that listing's verdict against its own record. This is where a percentage off a list price does the most damage - and where the tier below is often the better buy. Each category page's premium section shows the arithmetic.

Per unit is the category's own axis: per TB for drives, per GB for memory and cards, per bay for NAS units, per VA for UPS units, per Gb/s for network cards, per RU for racks. Condition is the cheapest offer's own. Current prices only; no past price is shown.
Live picks below, ranked cheapest first, each with a verdict badge comparing it to its own tracked history - not to any list price.

The cheapest in-stock drive from each flagship line we track (Samsung 9100 PRO and 990 PRO, WD SN8100 and SN850X, Crucial T705, T700 and T710, Corsair MP700, SanDisk GX PRO, Seagate FireCuda 530/540), any capacity - the same rows as the gaming SSD page, which compares every capacity.
The full external drive hub compares every tracked model.
106 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.

The tier above the cheapest boxes - every unit with four or more bays, by the bay count we hold for it. Units we started tracking today read TRACKING: no price history yet, so no verdict. Every NAS unit, measured.
The cheapest card at each VRAM size its listing states - the memory that decides what fits. We do not say which models a card can run. All 47 cards are new to our tracking (from 6 October 2026) and read TRACKING. Every card by VRAM, plus 96/128GB DDR5, Gen5 NVMe and unified-memory boxes.
Prebuilts with the graphics card, RAM and SSD each title states, and the parts to build or upgrade one. All are new to our tracking (from 6 October 2026) and read TRACKING; we publish no performance verdicts. All 107 prebuilts, graphics cards by VRAM, CPUs, DDR5, PSUs and coolers, and the SSDs to upgrade one, measured against their own history.
Judged on the storage and network facts each listing states - RAM ceiling and whether it is upgradeable, M.2 slots, 2.5GbE - with "Not sourced" where it states none. All 87 are new to our tracking (from 6 October 2026), so every one reads TRACKING. All mini PCs, by home-server, NAS-host and upgradeable-RAM use.
Fifteen more categories, grouped so they do not bury the ones above. Each group shows at most three picks: one per category, that category's cheapest in-stock product (cheapest per GB where it is priced per GB), from the first three categories in the group. Everything else is one click away. Specifications are each listing title's own statement, a compatibility claim is quoted as the seller's, and most of these products are new to our tracking, so their badge reads TRACKING rather than a verdict.
Thunderbolt & USB4 docks Β· NVMe & M.2 enclosures Β· Drive caddies, trays & adapters Β· Drive docks & duplicators Β· DAS & RAID enclosures Β· USB flash drives
CFexpress & SD camera cards Β· Raspberry Pi & SBC storage Β· NAS upgrades: RAM, NICs & cache
HBAs, RAID & SATA cards Β· SAS & SATA cables Β· KVM switches & remote access Β· DIY NAS cases & boards Β· 2.5GbE & 10GbE home networking
These five would have been a fourth page over products another category already holds, so they are cuts of that category instead. Each states the rule it applies.
M.2 2230 NVMe SSDs from our consumer SSD tracking (form factor as stored from the title), the cheapest per capacity. Whether a drive fits a given handheld is not something we verify; the 2230 length is the title's. Consumer SSDs Β· Steam Deck SSD Β· 2230 vs 2280
M.2 2280 NVMe SSDs from our consumer SSD tracking with no heatsink stated or flagged, the cheapest per capacity from 512GB. Laptop memory is on the consumer RAM page. Consumer SSDs Β· Laptop RAM
Docks, enclosures and other new-category products whose own title states a Mac fit - the seller's claim, quoted in the Spec cell. The cheapest four. Thunderbolt docks Β· NVMe enclosures Β· Portable SSDs
The two cheapest mini PCs whose listing states 2.5GbE or faster, the cheapest KVM over IP and the cheapest multi-gig switch. Mini PCs Β· KVM Β· 2.5GbE and 10GbE Β· Racks
The two cheapest external hard drives per terabyte (fraud floor and scalper flag applied by that page's layer) and the two cheapest LTO cartridges per native terabyte. External drives Β· LTO tape
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: $4.94/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 11 qualifying capacities with at least three models each - recertified enterprise drives run 35.6% 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 36% 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 recorded for that specific item over the days we tracked it in the last 30 - the badge prints how many days that is - in a record where its price has actually moved - a price that has held steady all month reads TYPICAL, because an unchanged price is not a low. 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.
