Adding extra storage to your desktop PC or laptop is always an option, and waiting for a great deal on a new solid-state drive (SSD) can get you more bytes for fewer bones. Whether you're looking to upgrade or build your own PC from the ground up, SK hynix has you covered with 2.5-inch SATA SSDs and M.2 PCIe NVMe SSDs. I've been using both of these drives in my main gaming PC since their launch, and it's been nothing but steady storage. And thanks to Prime Day savings, you won't be paying anywhere close to the regular price.

M.2 PCIe NVMe SSD

SK hynix Gold P31

Available in 500GB and 1TB sizes

Prefer your storage to be real fast? The Gold P31 PCIe NVMe SSD is no doubt what you're looking for. Prices start at $60 for the 500GB option.

2.5-inch SATA SSD

SK hynix Gold S31

Available in 250GB, 500GB, and 1TB sizes

If you need some bulk storage and have a spot open for a 2.5-inch SATA SSD, the Gold S31 is a stellar solution. Prices start at just $36 for the 250GB drive.

The 2.5-inch SATA SK hynix Gold S31 is a great option for desktop builds that need bulk storage at an affordable price. Prime Day pricing has the 250GB model down to about $36, which is a savings of about $29 from its MSRP. Moving up to the 500GB model, you can grab it for about $46, which is about $54 off the MSRP. And to save the most money, the 1TB drive is down to about $84, around $76 off the MSRP.

The Gold S31 earned the Windows Central Recommended Award in my review thanks to a five-year warranty, competitive price (made better for Prime Day), strong endurance, and stellar performance. Here's how it matches up to some other popular SSDs on the market.
