Samsung, Samsung 990 SSD without DRAM It is preparing a lower-cost option in the PCIe 4.0 market with its model. The product page, which remained briefly on the company’s website, revealed the key technical details of the drive before the launch. Accordingly, 2 TB model 7,250MB/s reading1 TB model 7.150MB/s reading reaches speed. Samsung removed the page, but the model name, capacity options and performance figures remained in online records.
The new driver appears as Samsung’s first 990 series model that does not carry the EVO or PRO tag. However, the 1 TB version, 6,450 MB/s sequential write While offering speed, the 2 TB version maintains the same value. Both models use M.2 2280 size and PCIe 4.0 x4 connectivity. Samsung has not yet announced the price, sales date and in which countries it will be sold.
The Samsung 990 does not carry the dedicated DRAM cache of traditional SSD designs and instead Host Memory Buffer uses technology. This feature allocates a small portion of the computer’s system memory to store address mapping data. Thus, the controller establishes the connection between logical addresses and physical locations on the NAND through the system memory. On the other hand, HMB cannot always achieve the latency values offered by dedicated DRAM and the response time in intensive workloads.
Removing DRAM from the drive helps Samsung reduce component cost and the number of parts on the circuit board. In addition, this choice opens up space for more competitive sales prices in a period when memory prices are rising. Although SSDs without DRAM can offer high sequential speeds in daily use, they may lose speed earlier during long-term writing operations. Especially large video files, archive transfers and intense multitasking make this difference more visible.
Samsung 990 maintains high transfer speeds while reducing cost with HMB
Leaked product information for 1TB Samsung 990 400 TBWfor 2TB version 800 TBW shows durability value. Additionally, Samsung is preparing to offer a three-year warranty for both capacity options. On the other hand, the company has not yet shared with the public the type of V-NAND used by the driver. The 400 TBW value in the 1 TB model strengthens the possibility of QLC NAND, but the official technical document does not confirm this detail.
QLC NAND increases storage density and reduces manufacturing cost by storing four bits of data in each memory cell. However, this type of memory lags in sustained write performance and overall write endurance compared to TLC NAND. MLC and SLC NAND provide higher durability, but manufacturers use these memory types mainly in corporate products. The actual NAND type of Samsung 990 will be determined with the specification table to be published by the company.
Performance values of Samsung 990, the brand’s 990 EVO Plus It is in a close range with the model. 1 TB 990 EVO Plus offers 7,150 MB/s reading and 6,300 MB/s writing speed. On the other hand, the new 990 model increases the writing speed to 6,450 MB/s while maintaining the same reading speed. However, the sustained write speed after the cache is full will show the real performance difference between the two models.
at the top of the series Samsung 990 PROIt reaches 7,450 MB/s reading and 6,900 MB/s writing speed in 1 TB capacity. In addition, 990 PRO offers 600 TBW endurance at the same capacity, surpassing the 400 TBW value of the new model. Thus, while the Samsung 990 approaches the upper class in sequential transfer speeds, it turns to more economical components in terms of durability and cache memory. Samsung has not yet announced the controller model, NAND manufacturing process and SLC cache capacity.
Price information will directly determine the place of the Samsung 990 against the 990 EVO Plus and 990 PRO. The lower price could make the drive accessible for gaming PCs, everyday desktop systems, and storage upgrades. However, DRAM models offer higher durability in jobs that require intensive content production and continuous data writing. Samsung’s official announcement will clarify capacity options and regional prices along with the sales date.
