Specs from the datasheet. Prices over time.
Every model here was read off the official datasheet by a person, field by field. Prices are captured again and again, so what you see is what a part has actually been selling for — not a list price a merchant picked.

Side by side
Same fields, every model, so a comparison is just a row
| Model | Interface | Capacity | Seq. read | Seq. write | TBW | Warranty |
|---|---|---|---|---|---|---|
| Drive A | PCIe 4.0 x4 | 2 TB | 7,000 MB/s | 6,850 MB/s | 1,200 TB | 5 yr |
| Drive B | PCIe 4.0 x4 | 2 TB | 7,450 MB/s | 6,900 MB/s | 1,400 TB | 5 yr |
| Drive C | PCIe 3.0 x4 | 1 TB | 3,500 MB/s | 3,000 MB/s | 600 TB | 3 yr |
Illustrative rows, drawn from the fields each catalog records.
Captured, not quoted
A price is read repeatedly over time, so the figure sits against what a model has been selling for rather than a single reading on a single day.
Your region's currency
Prices show in the currency of the region in the address bar, and every price table states when each figure was captured.
Nothing invented
Where a maker doesn't publish a figure — transfer rates on external drives, say — this site leaves the row out rather than estimating it.
Read the specs before you spend anything
The guides explain what each field on a datasheet actually changes — which numbers move a build and which are marketing.
