SK Hynix has been making RAM for decades, but it's only gotten into selling SSDs like this one recently. The SK Hynix Gold S31 is 36% off for Amazon Prime Day (opens in new tab), and that makes it one of the best SATA SSD deals we've seen, at only $102 for 1TB. 

Unlike some other budget drives out there, The Gold SD1 doesn't skimp on important tech. It has a DRAM cache, which helps improve write speeds. The S31 is rated for 560 MB/s reads and 525 MB/s writes. Basically, if you're looking for a faster SSD than this, it's time to spring for an NVMe drive. But this is an excellent drive for a big game library (or a small game library, if it includes Call of Duty: Modern Warfare).
