SK hynix isn't the most well-known name in SSDs, but the company's Gold P31 M.2 NVMe SSDs and its Gold S31 SATA SSDs both took the top of our performance charts in their reviews - with both SSD families winning 4.5 stars out of 5 and an Editor's Choice award. That makes the company's across-the-board discounts for Prime Day stand out as exceptionally good deals, especially as the company has emerged as one of Samsung's most potent foes in the SSD market. 

Update: The coupon for the 1TB P31 M.2 has expired.

These M.2 NVMe SSDs represent top-tier SSD tech, with the world's first 128-layer flash under the hood and custom SSD controllers that delivered exceptional performance throughout our demanding suite of benchmarks. 

The company has marked down one of its M.2 NVMe SSDs, the P31 500GB model, to $59 (the 1TB model's deal expired). These drives come with impressive specs (table below) and feature competitive endurance and a five-year warranty, so you can buy with confidence.

The 500GB SK hynix Gold P31 is a great upgrade to boost your system's performance and it has the bare minimum amount of storage needed for most gamers. It also won the Tom's Hardware Editor's Choice award.View Deal

SK hynix also slashed the pricing on three of its SATA models, which come with 72-layer flash and custom SSD controllers. The 1TB model now retails for $83, the 500GB model is $45, and the 250GB SSD drops down to a mere $35. The 250GB model isn't big enough for most users, but the price point is tempting for systems that don't need a large boot drive.

The 1TB SK hynix Gold S31 has enough capacity for almost anyone, including serious gamers and professionals. It also won the Tom's Hardware Editor's Choice award.

SK hynix Gold S31 250GB: was $64 now $35 (with coupon)
The 250GB SK hynix S31 is good if you only need enough space to store the operating system and a few programs. For most of us, this is only a good option if you have a big HDD (or SSD) to store everything else.

The table above outlines the performance specifications of the drives. The NVMe models offer up to a peak of 3,500/3,200 MBPs of sequential read/write throughput, and 570,000/600,000 random read/write IOPS. Performance varies by capacity, though. 

The SATA drives top out at 560/525 MBps of sequential read/write throughput, and 95,000/87,000 random/read write IOPS. Again, performance varies by capacity. 

Both types of drives have very competitive endurance ratings, earning praise from our SSD reviewer, and come with long five-year warranties. SK hynix also throws in cloning software to help you move your data over from an older drive.
