SK Hynix has been making RAM for decades, but only recently has it embarked on selling SSDs like this one: the SK Hynix Gold S31 is 36% off on Amazon Prime Day, and at just $102 for 1 TB, it's one of the best deals we've seen on It is one of the best SATA SSDs we have seen.

Unlike other budget drives, the Gold SD1 does not skimp on key technologies. It has a DRAM cache that helps improve write speeds; the S31 is rated at 560MB/s read and 525MB/s write. Basically, if you are looking for an SSD faster than this, it is time to buy an NVMe drive. However, this is a great drive for large game libraries (or small game libraries, if you include Call of Duty: Modern Warfare).
