The New Gold Standard for PCIe 4.0 Gaming
The WD_BLACK SN850X in the 2TB capacity is a definitive update to an already legendary line, firmly positioning itself as a top-tier performer in the PCIe Gen 4 NVMe market. For any modern enthusiast or power user—especially gamers running large titles on a high-performance system like my Windows machine, Gengar—this drive provides a tangible upgrade in responsiveness, load times, and overall system snappiness. Blazing Speed and Consistent Performance The advertised sequential read speed of up to 7,300 MB/s is backed up by equally impressive sequential writes of up to 6,600 MB/s (for the 2TB model). These speeds are pushing the theoretical limits of the PCIe 4.0 interface. Gaming Load Times: The most noticeable benefit is the near-instantaneous loading of huge environments in modern games. The drive's strong random read/write IOPS performance (up to 1,200K/1,100K) means not only do sequential transfers fly, but the small-file operations that govern OS responsiveness and application launching are incredibly fast. Sustained Transfers: Unlike some budget drives that choke after transferring a large file, the SN850X maintains its blistering speed. This is crucial for content creators or engineers who frequently move massive media libraries or project files. Endurance and Longevity The 2TB model is rated for 1,200 TBW (Terabytes Written), backed by a 5-year limited warranty. This endurance rating is excellent for a consumer drive and offers significant peace of mind. Given that the average user rarely hits these thresholds, this drive is built to last far beyond the typical upgrade cycle. Form Factor and Management The standard M.2 2280 form factor makes installation straightforward in nearly any desktop or laptop supporting PCIe Gen 4. For those installing into systems with limited airflow, the non-heatsink version is sleek and easily fits under a motherboard's built-in M.2 thermal guard. Western Digital's WD_BLACK Dashboard software is worth downloading (for Windows users). It allows you to monitor drive health, thermal performance, and activate Game Mode 2.0. This feature is designed to optimize the drive’s operation when detecting game launches, ensuring maximum sustained speed by disabling low power states and prioritizing game-related I/O. The Verdict If you are currently running an older PCIe 3.0 NVMe drive or, worse, a SATA SSD, the WD_BLACK SN850X is arguably the best single upgrade you can make to your PC. It offers world-class performance for the PCIe 4.0 generation, excellent longevity, and the reliable engineering expected from the WD_BLACK line. For a primary boot/gaming drive that will eliminate loading screens and maintain rapid response times, this 2TB model is a stellar, professional choice.

Playstation 5 konsolümüm hafızasını genişletmek için ürünü önce Amazon Germany üzerinden almıştım fakat zamanında teslim olmayacağı için iptal edip neredeyse aynı paraya Amazon.com.tr'den satın aldım. Ürün kesinlikle vaad ettiği hızları görüyor. Ps5'de işlem ve depolama hızı isteyen oyunlarımın tamamını sorunsuz şekilde oynabiliyorum. Tek eksiği (ki bunu aşmak çok kolay) soğutucusunun olmaması. Ben harici bir soğutucu alarak bu sorunu bertaraf ettim. Ps5'de hafıza sorunu yaşayanlar biçilmiş kaftan.

Semplicemente mostruoso. Ho installato la versione da 2TB sul mio fisso e il salto di qualità è stato immediato. Windows si avvia in un lampo e i tempi di caricamento nei giochi sono praticamente spariti. Mai un rallentamento, temperature ottime e affidabilità top. Se volete il massimo per il vostro PC, è l'acquisto da fare. Mai più senza!
