Price per terabyte is the only number that makes drives of different sizes comparable. Type in the price and capacity of any listing and the calculator returns $/TB, $/GB, and a verdict against the street-price sample we keep on the SSD Price Index page. No retailer data is stored; the comparison bands are updated monthly and dated.
Rule of thumb for October 2026: the current street sample runs $133–$250/TB with a median of $185/TB (TrendForce WW SSD Street Price, 16 Oct 2026). Below about $140/TB is unusually cheap and worth a second look at seller and NAND type; $140–$200/TB is normal for a mainstream Gen 4 or SATA drive; above $200/TB is flagship, Gen 5 or 8TB territory.
Enter a price and a capacity to see the price per terabyte and how it compares with the current street sample (2026-10-16).
Verdict bands as of 2026-10-16, based on the price per TB of the five SKUs in the TrendForce street sample above (lowest $133/TB, median $185/TB, highest $250/TB). They describe where a price sits relative to that sample; they are not a recommendation to buy a particular drive.
These are the retail prices the verdict is measured against. They are a small, dated sample published by TrendForce WW SSD Street Price — useful as a yardstick, not a complete market survey:

The bands move with the market, and the market in October 2026 is shaped by a NAND Flash shortage driven by AI data-center demand.
