The 990 SSD is an interesting product because it is one of the few SSDs released after the AI pricing crunch sent storage prices into orbit. As such, we know what Samsung thinks this drive is worth in the current climate, namely $529. While 2TB of storage would have been much cheaper a year ago, a 38% discount on a new SSD is not to be sniffed at, especially given all signs point to these drives getting more expensive, not cheaper, in the future.
We reviewed this drive at launch last month and liked its full-fledged Gen 4 throughput, decent power consumption, and good all-around performance. The 990 is essentially a QLC-based 990 EVO Plus, featuring Samsung's PiccoloQ controller and V9 QLC Flash memory.
As you can see from our testing data, it scores very close to the 990 EVO Plus in latency testing, while beating the 990 EVO drive in bandwidth and 3DMark overall score.

This drive also scored well in our PS5 test, so this drive could serve as an expansion drive for your shiny new PlayStation if you so choose. At its original list price, this drive makes no sense as a purchase up against the 990 Pro or Samsung's Gen 5 9100, but at this price it is a good chunk cheaper than both of those options.
As we approach the end of 2026, these storage prices remain tough to stomach, but things don't look like they are going to improve any time soon. In fact, all signs point to the AI pricing crunch continuing to make things worse going forward, meaning leaving it too long could make storage even more expensive in the future.
