The new ones Samsung 990 Pro SSD are already official, but instead of moving to the new standard PCI Express 5.0, where several manufacturers have already made their proposals visible, Samsung has preferred to stay with PCI Express 4.0 and add an RGB heatsink. Therefore, its maximum speed remains at 7,450 MB/s for reading and 6,900 MB/s for writing due to limitations of its own PCIe Gen4 x4. Random access will reach 1.4 million read IOPS and 1.55 million write IOPS
It is true that there are still not many computers compatible with PCIe 5.0, but it is striking that Samsung, whose line of high-performance SSDs had become a benchmark, has fallen behind in this race. It is true that, within PCIe 4.0, the 990 Pro is one of the fastest SSDs, but soon PCIe 5.0 will be extended. In fact, the latest rumors and leaks seemed to indicate that the 990 Pro would have PCI Express 5.0, but in the end this has not been the case.
In addition to the model with a heatsink and colored lights, there will also be a version without a heatsink that will delegate the cooling to a small metal sheet. This version will be indicated for laptops and systems such as motherboards that already have their own heatsink.
The Samsung 990 Pro integrate triple bit per cell (TLC) 3D VNAND Flash memories and each model has a 1, 2 and 4 GB LPDDR4 RAM memory cache depending on capacity (1.2 and 4 TB)
In both cases, we will have models with capacities of 1 TB, 2 TB and 4 TB, although the latter will arrive in 2023. Meanwhile, the 1 and 2 TB models with a heatsink will have prices of 179 and 309 dollars, respectively.
