Samsung's 990 SSD enters the market as a PCIe 4.0 offering, presenting a mixed bag of competitive performance and questionable pricing. While it delivers respectable sequential and random speeds, its cost often places it at a disadvantage when compared to more aggressively priced alternatives. The drive's design, including its single-sided form factor, makes it a viable option for a range of uses, from PC builds to PlayStation 5 expansions. However, its market positioning as an 'affordable' option is undermined by its relatively high retail price, especially in a landscape with strong contenders offering similar or superior performance for less.
Despite its performance being generally adequate for most users, particularly those not engaged in highly intensive computing tasks, the Samsung 990 struggles to stand out against rivals that offer better speed-to-price ratios. This review explores the technical specifications, real-world test results, and overall market value of the 990 SSD, providing a comprehensive assessment for potential buyers. It delves into how the drive stacks up against competitors in terms of read and write speeds, game loading times, and file transfer rates, ultimately helping consumers decide if the Samsung 990 is the right choice for their storage needs.
Understanding the Samsung 990's Design and Features
The Samsung 990 SSD is designed as a PCIe 4.0 solid-state drive, aiming to provide robust storage solutions for both personal computers and the PlayStation 5 console. It features a standard M.2 2280 form factor, ensuring broad compatibility with modern motherboards and console expansion slots. A notable aspect of its physical design is the single-sided configuration, which is particularly advantageous for PS5 users, as it allows for easier integration with a heatsink, crucial for maintaining optimal operating temperatures during demanding use. The drive is available in various capacities, including a 1TB model and a larger 2TB variant, catering to different storage requirements for games and applications.
Under the hood, the Samsung 990 incorporates Samsung's proprietary PiccoloQ controller and V9 QLC NAND. Unlike some high-end SSDs, it forgoes a dedicated DRAM cache in favor of Host Memory Buffer (HMB) technology, a common approach in more value-oriented drives. This means the SSD utilizes a portion of the system's RAM for data caching, which is generally sufficient for everyday tasks and gaming, though it might not match the performance of drives with dedicated DRAM in extremely demanding, scientific computing scenarios. The reliability of the 990 is supported by a respectable endurance rating, with the 1TB model offering 400TBW (Terabytes Written) and the 2TB model doubling that to 800TBW, aligning with industry standards for consumer-grade SSDs.
Performance Analysis and Market Comparison
In terms of performance, the Samsung 990 delivers solid sequential read and write speeds, registering approximately 7208.62 MB/s for reads and 5762.93 MB/s for writes in synthetic benchmarks like CrystalDiskMark 8. While its read speeds are close to Samsung's claims, the write speeds occasionally fall short when compared to some of its competitors. Random 4K performance, which is more indicative of real-world application and game loading times, positions the 990 as an average performer against rivals such as the Crucial P310 and WD Black SN7100. For instance, game loading times, as observed in the Final Fantasy XIV Endwalker benchmark, were adequate but a bit slower than those offered by competing drives, highlighting a slight deficit in responsiveness.
Real-world file transfer tests further illustrate its capabilities, with a 120GB file transfer completing in about 40.3 seconds, achieving an average transfer rate of 2.98GB/s. This places it competitively within its segment for bulk data operations. However, the Samsung 990 faces significant challenges in value-oriented benchmarks like PCMark 10's Data Drive and Quick System Drive tests, where its scores are more aligned with budget-friendly drives rather than premium offerings. This disparity between its performance and its comparatively high retail price, particularly the 1TB model priced at $269.99, makes it a less compelling option for consumers seeking optimal performance per dollar. Many alternatives offer stronger overall performance, better random access speeds, and more aggressive pricing, making them more attractive choices for users prioritizing cost-effectiveness without significant compromises on speed.
