SK hynix Gold S31
SATA · 1TB · 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.
