Samsung only started the Samsung 990 PRO SSD connected via PCIe 4.0. This choice may surprise some since PCIe 5.0 is just around the corner, but these interfaces are often not the bottleneck for storage devices in real-world conditions.
The company claims that this new SSD can reach 7450 MB/s (read) and 6900 MB/s (write) at around 1500,000 IOPS. That’s about 50% better than the excellent 980 PRO SSD. We’ll have to wait for independent reviews to confirm this, but it seems believable.
Energy efficiency is also said to be 50% higher, which could have a significant impact on heat dissipation and power consumption. For frequent users there is a version with a stronger heat sink (but no RGB?).
Samsung is promoting this SSD to gamers and creative users, which makes sense as they present the perfect use case for such a product. They also spend a lot of money when it comes to buying the best performance.
The Samsung 990 PRO is available in 1TB, 2TB or 4TB capacities and all feature 1GB LPDDR4 DRAM cache per 1TB for a maximum of 4GB. They support full disk encryption and come with a 5-year limited warranty.
Perhaps the best feature is the pricing. At $179, the 1TB 990 PRO is particularly attractive. The 2TB costs $309, and we don’t know the price of the 4TB version or the release date.
