SK hynix Gold S31 Spec and Price in the United States
Released August 15, 2019 · $123.99 MSRP
The Gold S31 is the only drive in this set built around a 1TB capacity point rather than 2TB, and its 600TB TBW endurance rating is exactly half the 1,200TB figure SK hynix rates on the Gold P31 and Platinum P41. It's a SATA drive with sequential speeds around 560/525 MB/s and a DRAM cache from the Quartz controller, priced at $123.99 — the lowest MSRP in this comparison. That combination points squarely at budget upgrades: replacing a spinning hard drive or an aging SATA SSD without needing NVMe.
Tied 87th of 106 models in the SSD catalog on Sequential read — 8 models share this figure. 93rd of 106 models in the SSD catalog on Sequential write.

What owners and reviewers say
Summarised from 1 source(s), reviewed September 13, 2026. A source is counted only where it names this model exactly. How we track prices
Commonly praised
- Review coverage places its sequential performance in the same tier as the best-known SATA drives of its generation, rather than clearly behind them.
- Reviewers single out its price against those same drives as its main reason to choose it.
- It ships with a free cloning and data-migration utility, which reviewers note as a practical inclusion for an upgrade.
- The five-year warranty is highlighted as matching the established SATA competition.
Commonly criticised
- Its SLC write cache is small, so sustained writes fall back to slower speeds sooner than reviewers would like.
- The line tops out at 1TB, which reviewers flag as a narrower range than competing SATA families offer.
