How to Choose the Best Internal Solid State Drives
Understanding Interface and Performance
When selecting an internal SSD, the interface type significantly dictates performance. PCIe Gen4 NVMe drives, such as the Samsung 990 PRO series or the WD_BLACK SN850X, offer sequential read speeds exceeding 7,000 MB/s, which is crucial for high-end gaming, 8K video editing, and complex data processing. These drives leverage the PCIe 4.0 standard to achieve remarkable bandwidth. In contrast, SATA III SSDs like the Samsung 870 EVO are limited by the SATA interface to approximately 560 MB/s. While still a massive upgrade from traditional HDDs, SATA drives are typically reserved for general computing, secondary storage, or older systems that lack M.2 NVMe slots. Users needing the fastest possible load times for large applications or games will find the investment in a Gen4 NVMe drive worthwhile.
Capacity and Longevity Considerations
Storage capacity is another primary factor. Drives range from 1TB, suitable for most users, up to 4TB or even 8TB, as seen with some WD_BLACK SN850X variants. For gamers with extensive libraries or professionals handling large datasets, higher capacities like the Samsung 990 PRO 4TB prevent frequent data management. The underlying NAND technology also plays a role in longevity and performance. Many modern SSDs, including the WD_Black SN7100 and SN850X, utilize TLC (Triple-Level Cell) 3D NAND, which balances cost, performance, and endurance. While specific endurance ratings (TBW - Terabytes Written) vary by model, TLC drives typically offer robust reliability for years of heavy use.
Form Factor and Thermal Management
Internal SSDs come in various form factors, with M.2 2280 being prevalent for NVMe drives, including all the top 5 PCIe Gen4 models listed. This compact stick-like design integrates directly into compatible motherboard slots, saving space. Conversely, SATA SSDs like the Samsung 870 EVO typically come in a 2.5-inch form factor, designed to fit into drive bays found in most desktop PCs and some laptops. For high-performance NVMe drives, thermal management is critical. Drives operating at peak speeds, such as the Samsung 990 PRO or WD_BLACK SN850X, can generate significant heat. The WD_BLACK SN850X even offers an optional heatsink version, which is particularly beneficial for sustained heavy workloads or gaming to prevent thermal throttling and maintain consistent performance.
Pros & Cons

Common Mistakes to Avoid
Ignoring Motherboard and System Compatibility
A frequent error involves purchasing a high-performance SSD without verifying system compatibility. For instance, a user might acquire a Samsung 990 PRO PCIe Gen4 NVMe drive but install it in a motherboard that only supports PCIe Gen3. While functional, the drive will be bottlenecked, delivering only a fraction of its advertised 7,450 MB/s read speeds. Similarly, attempting to install an M.2 2280 NVMe drive into a system that only has 2.5-inch SATA bays, compatible with a Samsung 870 EVO, is a common oversight.
Underestimating Thermal Management Needs for NVMe
High-speed NVMe drives like the WD_BLACK SN850X or the Samsung 990 PRO generate considerable heat during sustained operations. A mistake is neglecting proper cooling, especially in compact builds or during heavy gaming sessions. The WD_BLACK SN850X explicitly offers an optional heatsink version for a reason; without it, these drives can experience thermal throttling, where performance is reduced to prevent overheating. This can negate the investment in a premium, fast SSD.
Choosing the Wrong Drive Type for the Workload
Another common misstep is selecting a drive type that doesn't align with the intended use. While a Samsung 870 EVO SATA III SSD provides excellent value and speed for general use or as a secondary drive, relying on it for high-end gaming or heavy data processing where a PCIe Gen4 drive like the WD_BLACK SN7100 would excel, leads to suboptimal performance. The main difference is the significant gap in sequential read/write speeds that directly impacts load times for large files and applications.
