When Samsung launched its 990 Pro family of SSDs for retail market last year, it only introduced 1 TB and 2 TB models, surprisingly omitting premium high-capacity 4 TB version. Now, the company is about to correct this wrong by launching 4 TB version this fall, the world's largest SSD supplier revealed in an X post.

"You wanted it so badly, we had no choice but to deliver," the company's post reads. "The 4TB 990 PRO by #SamsungSSD is coming. Same blazing-fast storage with double the max capacity for gaming, video, 3D editing, and more. Stay tuned for more details."

From performance point of view, Samsung's 990 Pro 4 TB drive offer an up to 7,450 MB/s sequential read speed and an up to 6,900 MB/s sequential write speed, which is in line with what 1 TB and 2 TB models offer. As for random operations, the SSD achieves 1,400,000 IOPS for reads and 1,550,000 IOPS for writes, which is comparable to the performance of other flagship SSDs.

Since Samsung's 990 Pro is a family of SSDs with a PCIe 4.0 x4 interface, the 4 TB drive may not attract attention of owners of shiny new systems based on AMD Ryzen 7000-series or Intel Core 12000 and 13000-series processors. However, there are loads of PCs with M.2 slots featuring a PCIe 4.0 interface just waiting for an upgrade and 4 TB SSD makes a lot of sense these days given low prices of 3D TLC NAND.

According to Samsung's spec sheets, the company intends to offer two versions of 990 Pro 4 TB SSDs: one with a simplistic graphene heat spreader to maximize compatibility with laptops, another with a larger aluminum heatsink to ensure consistent performance under high loads.

Samsung has not formally disclosed MSRP of its Samsung 990 Pro 4 TB SSD, though expect it to be priced in line with market realities. The drive is covered with a five-year limited warranty with an endurance rating of 2400 terabytes written (TBW).

    "You wanted it so badly, we had no choice but to deliver,..."
    Maybe you should apply that to those who want MLC, like the PRO line used to use, as well...

    For that, you'll have to want it so badly that you buy enterprise products instead :(

    Goody...time for a new acronym... 1.4 MIOPS.

    and storage devices getting RAM from 1-4GB DDR4 (almost) like main systems (almost comparable peripherals upgrade like with GPU memory, but these are more than single task devices and can share their RAM, up to 48GB(?, e.g. RTX8000) at the moment)

    [ well, with Linux and enabling swap tasks, somehow storage devices possibly would indirectly share RAM also (with memory RAM being completely distributed within activated processes), if swap files are limited to that RAM size for each storage device(?) ]

    1-4GB ram?. We use a minimum of 16GB these days. I wouldn't want a drive without some DRAM. The system responsiveness difference to me is huge.

    is this a Rip Van Winkle moment??? random writes exceed random reads?? when did that happen?
  • Ryan Smith - Monday, August 28, 2023 - link

    Random writes go to the pSLC cache. Random reads are against the TLC NAND.

    Writes started exceeding reads when high-end SSDs switched from MLC to TLC. It's become more pronounced with some of the latest generation drives, though.

    It'll probably be $399 at launch...

    Did you forget the zero from the end of you numbers?
    Well in reality something like $800-$1000 sounds plausible MSRP. Normally higher capasity ssd has been more expensive / GB than the smaller ones... And the MSRP for 2gb model was $268
