Consumer NVMe and SATA drives

A drive is chosen on three things in this order: does it physically fit the slot, does the slot run at the speed you are paying for, and is the capacity right. Speed ratings are the part most often oversold, so the fields that decide real behaviour are kept visible above. Prices are not published here, and the reason is a permission problem rather than a technical one.

Compare the same kind of drive

The list holds 190 internal consumer drive configurations from 13 makers, including Samsung, Western Digital, SK hynix, Kingston, Solidigm, Seagate, ADATA, Lexar, PNY, Sabrent, Silicon Power, TeamGroup and Transcend. Recorded nominal capacities run from 128 GB to 8 TB. Most rows are M.2 2280 NVMe drives on PCIe 3.0, 4.0 or 5.0, and the list also holds shorter M.2 2230 and 2242 drives and 2.5-inch SATA drives. It does not cover external, enterprise, or removable storage. Read 26 July 2026: Kingston gaming SSD catalog.

Capacity, interface, form factor, controller, NAND type, and DRAM-cache status are recorded for all 190 rows; endurance is recorded for 125. A missing field is shown as not recorded; it is not a zero, an inferior specification, or permission to assume that two similar product names use the same controller or NAND revision.

Decide in this order

1. Capacity: compare offers at the same usable class rather than treating a lower total price for a smaller drive as better value. The captured configurations use both decimal labels such as 1 TB and binary-sized labels such as 1024 GB, so the exact manufacturer configuration stays attached to each row.

2. Interface and platform fit: check the slot and interface supported by the system before paying for a higher-interface model. The list distinguishes PCIe 4.0 x4, PCIe 5.0 x4, and the dual-mode interface recorded for Samsung 990 EVO Plus. It does not contain a motherboard-compatibility verdict for your system.

3. Sustained-use evidence: check endurance, warranty, controller, NAND revision, and workload-specific test evidence for the exact drive. Those fields are not complete in this list, and headline sequential speeds alone do not fill the gaps. Western Digital SN8100 and Kingston gaming SSD specifications, retrieved 26 July 2026.

4. Exact revision and part number: keep silent controller or NAND revisions separate when the evidence identifies them. The matching method quarantines conflicting capacity, revision, form-factor, and part-number evidence instead of merging it into a convenient price row.

Availability is not inferred from existence

Seventy-five of the 190 drives carry an official current availability action, 109 show as US stock not shown, and six are recorded as withdrawn by the maker. The withdrawn rows stay in the list so a discontinued product cannot quietly be counted as available. A current maker action still does not prove stock at a particular retailer.

Crucial is absent because its official catalog returned a web-application-firewall block during retrieval. This list is therefore a bounded sample of what we could read from official sources, not the full US SSD market and not a market-share sample.

What would make a price comparison valid

Each retained offer must preserve the same exact drive, capacity, controller and NAND revision when known, form factor, condition, merchant, source URL, and fetch time. It also needs a stable group of sources so a missing merchant cannot masquerade as a price movement. Only after the 14-day, 10-observation, and 60% coverage requirements are all satisfied can the site calculate a retrospective position within the observed window. Price per terabyte remains unavailable until an eligible price exists for the exact capacity; a missing price is never treated as zero.
