1.0 out of 5 stars Performance is abysmal
By Robert J. on August 19, 2019
First off, one has to accept SK hynix's terms and conditions without being able to read them (they are sealed inside the box and by opening the box you agree to the Ts & Cs - although there is a short summary on the box).

Second, the performance is abysmal. Several benchmarks show that it writes FASTER than it reads. This is exactly the opposite of the way it is supposed to be. The third photo shows the performance of a CHN SSD. Another benchmark shows the CHN SSD average read speed at 7,900.68 MB/sec whereas this drive is 1939.57 MB/sec.

I certainly expected better performance than this!

5.0 out of 5 stars Terrific performance, endurance, and value. What's not to love?
By Andrew Finch-Craver on October 16, 2019
As a system builder, I admit that I'm quite picky when it comes to the quality and performance of the PC parts I choose to purchase. I've used an SK Hynix SSD as my personal boot drive for a few years and it has performed perfectly. When I decided to upgrade a storage drive from traditional mechanical to an SSD, it was a no brainer to choose this 1TB Gold model from SK Hynix. It achieves excellent SATA performance (see benchmark screenshots), is currently priced very competitively, and boasts top notch endurance (600 terabytes written) that's backed by a lengthy (5 year) warranty. Beautiful. If only they came in 2 or 4TB options...

5.0 out of 5 stars GREAT SSD
By UM on September 3, 2019
Overall, I am satisfied with SK hynix Gold S31 1TB.
It would be much much better or maybe getting more interest from customers if it was around $115.
However, it is still a good product and I feel like it is a budget Evo (Samsung) version.
5-year warranty: Same as Evo, Crucial,
Write/Read speed: Reasonable (Picture),
Stable temperature: Around 30'C (at idle).

*The speed test result is not always the same (sometimes higher/lower). it has been tested with 2011 Macbook Pro 15".

5.0 out of 5 stars Excellent drive for the price
By AJ on October 15, 2019
Love this little drive! It upgraded my out-of-the-box PC to a gaming champ. I did some research and saw that SK hynix just started offering the 1 TB SSD in the US, so I decided to give it a try. Personally, this is now my go-to option for upgrading PCs, especially if you're looking to cut startup time and run games. No frame drop, no lag, and now my computer will last for a few more years before I have to upgrade it! As a gamer and streamer, I'm thrilled to save a few thousand bucks on a new computer. I'll probably order another one for my work computer too since it's been so nice.
