When Samsung announced its 990 Pro SSD family for the retail market last year, it only offered 1TB and 2TB variants, skipping the 4TB option that is usually available for high-end SSDs. Now, the company is poised to right this by releasing a 4TB version this autumn.
In terms of performance, Samsung’s 990 Pro 4TB drive offers up to 7,450 MB/s sequential read speed and up to 6,900 MB/s sequential write speed, which is comparable to the 1TB and 2TB versions. In terms of random operations, the SSD achieves 1,400,000 IOPS for reads and 1,550,000 IOPS for writes, matching the performance of other flagship SSDs.
According to Samsung’s specifications, the 990 Pro 4TB SSD will be available in two variants: one with a simple graphene heat spreader to maximize compatibility with laptops, and another with a bigger aluminum heatsink to provide constant performance under heavy loads. The drive has a five-year limited guarantee, 4GB of LPDDR4 DRAM cache, and a capacity of 2400 terabytes written (TBW).
The 4TB drive may not appeal to owners of brand new systems based on AMD Ryzen 7000-series or Intel Core 12th and 13th Gen Core series CPUs since Samsung’s 990 Pro uses a PCIe 4.0 x4 interface. However, there are many PCs with M.2 slots and a PCIe 4.0 interface that are simply waiting for an update, and a 4TB SSD makes a lot of sense these days considering the cheap pricing of 3D TLC NAND.
Samsung has not yet released the MSRP and release date of the Samsung 990 Pro 4TB SSD, but those details should be revealed soon.

ComputerWorksUg says: Seeing as the 990 Pro is already one of the most expensive PCIe 4.0 SSDs on the market, the 4TB option shouldn’t come cheap, especially considering that 4TB SSDs are usually more than double the price of their 2TB variants.
