SK hynix first stepped into the consumer SSD market in 2019 with its Gold S31 2.5-inch SATA SSD (opens in new tab), a durable SSD with strong performance and a competitive price. Now, the Gold P31 aims to fill the needs of gamers, creators, and designers who require a high-performance, reliable, and competitively priced M.2 SSD that works with the PCIe (3.0) NVMe interface. It also happens to be the first 128-layer NAND flash-based SSD available on the consumer market, allowing for modest power consumption and strong performance.

The 500GB and 1TB options are expected to hit 3,500 MB/s sequential read speeds, while the 500GB model should hit 3,100 MB/s and the 1TB model 3,200 MB/s write speeds. The 1TB model also comes with a 750 TBW rating, which means you should be able to write up to 750 terabytes of data before seeing a failure. All SSDs come with a strong five-year warranty to help protect your purchase.

Affordable accessories that'll pair perfectly with your PC

Every one of these awesome PC accessories will enhance your everyday experience — and none cost more than $30.

KLIM Aim RGB gaming mouse (opens in new tab) ($30 at Amazon)

Whether you're a gamer or not, this is an absurdly good mouse for the price. It's ambidextrous, has a responsive sensor, a braided cable, tank-like build quality, and, yes, it has RGB lighting, though you can turn it off if that's not your thing.

AmazonBasics USB speakers (opens in new tab) ($16 at Amazon)

These neat little speakers may only pack 2.4W of total power, but don't let that fool you. For something so small you get a well-rounded sound and a stylish design. And they only cost $16.

Razer mouse bungee (opens in new tab) ($20 at Amazon)

Use a wired mouse? You need a mouse bungee to keep your cable tidy and free of snags. You get no drag on the cable, and this one has subtle styling, a rust-resistant spring and a weighted base, all for $20.
