WD_BLACK 4TB SN850X NVMe Internal Gaming SSD Solid State Drive - Gen4 PCIe, M.2 2280, Up to 7,300 MB/s - WDS400T2X0E

It works perfectly and is super fast. It is exactly what I needed to expand my computer's storage.

This SSD, its a no brianer to get one my open world games both RPG, and MMOS are smooth, no freezes, fast, this ssd is just blazing fast i am planing to get another 4tb of this one, and that review after 7 months of use ! 👍🏻

At 200 a pop for the 1TB version, this is a steal. Literally cheaper than Gen 3 drives 😂

Normally I do not write reviews, but this ssd is a beast. I have XPS 9710 I clone drive C to the new SSD 4TB and the performance such as copying pasting photoshop open folders are very fast and noticeable.

It's really a beast, I' am using this is my victus gaming laptop. I love this, I am playing GTA V, Horizon forza etc heavy end games without any lag. I know this performance is also depend on other components. But this nvme is doing maximum from the storage disk side. 7300 Mb/s read speed as per they advertised. Really recommended.

Price is very reasonable and it works buttery smooth . This might be your exchange for Samsung 990 too ; as it is expensive

Excellent sustained performance, not only in synthetic benchmarks but also in the real world! The WD SSD Dashboard makes it a breeze to check for and install firmware updates, check the drives temps and health!

The best SSD so far, for having tons of games at one place it’s definitely worth it! No issues.

szybki ale stanowczo za drogi

Używany w obudowie Thunderbolt 4 z aktywnym chłodzeniem. No wymiata. PE-TAR-DA.

The most important bit here is that it wasn't affected by "that" Windows 11 update that has been making a hash of other storage sticks in recent weeks. I installed Win 11 fresh, all the updates, all the office apps, some big games (all 50Gb+) without a problem. "Read speeds up to 7300 MB/s, Write speeds up to 6,600 MB/s"? Well, yes, actually. Pretty much on point to the claimed speeds which is surprising. Considering this isn't the latest gen PCI connector, but also considering I'm coming from "old" 2.5" SSDs and even a 4Tb platter SATA drive (5300rpm, lol), the speed at which this does its job feels insane, like we're living in the future. 4Tb on this tiny tiny stick. It's mad how far we've come. In the motherboard I have with a decent size heatsink on it, HW Info reported about 30-35 deg C even under load, so I stopped measuring it. Although I did make a new PC build with it (AMD 9800X3D, 5070Ti, MSI Mag Tomahawk X970E motherboard, Lexar Ares RGB 6000Mhz mem), bear in mind I have max 100Mpbs 5G connection for my rural internet. Previously downloading games of 50Gb plus would need me to leave the PC on overnight. With this build, Doom Dark Ages downloaded in about 90 mins. No exaggeration. I installed windows 11 fresh in about the same time, probably less. Office 365 was downloaded and installed in a ridiculously short amount of time. Maybe it's the CPU too, maybe it's the motherboard and Wifi 6 vs the old mobo having a 1Gb ethernet but I doubt that makes THAT much of a difference over a max 100Mpbs internet connection. Boot times are less than 10 seconds. I should time it, but it's almost like the PC is in sleep mode when booting from a "cold" power on. Loading "heavy" games (eg Doom Dark Ages, Indiana Jones Great Circle etc) is similarly insanely fast. Very happy with the purchase. More so as it was from Amazon Resale as "Good" (it's been perfect and about €20-40 cheaper than new new). I will probably end up getting a second one in time.

El WD_BLACK SN850X NVMe SSD de 4TB es una auténtica bestia en cuanto a velocidad y rendimiento. Desde que lo instalé en una placa compatible con PCIe Gen4, los tiempos de carga se han reducido a niveles mínimos, tanto en juegos como en software de edición pesada. Las velocidades que he medido se acercan mucho a lo prometido: hasta 7300 MB/s en lectura y 6600 MB/s en escritura, lo que permite un acceso casi instantáneo a cualquier archivo o aplicación. Como gamer, se nota inmediatamente el impacto: los mapas cargan al instante, las texturas aparecen sin esperas y todo se ejecuta con una fluidez impecable. El modo para juegos 2.0 añade una capa extra de optimización, con carga predictiva que realmente marca la diferencia en títulos de mundo abierto o con muchos elementos dinámicos. En cuanto al espacio, los 4TB son perfectos para mantener una biblioteca de juegos moderna (muchos de ellos superan los 100 o incluso 200 GB), además de espacio para grabaciones, mods o proyectos personales. Para quienes producen contenido o usan software como Unreal Engine, Blender o DaVinci Resolve, este SSD también responde con la misma agilidad. Aunque esta versión no incluye el disipador de calor, su rendimiento se mantiene muy estable en condiciones normales gracias a una buena gestión térmica del sistema. Si planeas sesiones prolongadas de juego o renderizado, puede valer la pena usarlo con una carcasa con refrigeración activa o en una placa con buen flujo de aire. En resumen, el WD_BLACK SN850X es una inversión excelente para gamers, creadores de contenido y usuarios avanzados que buscan lo mejor del almacenamiento PCIe Gen4. Rápido, fiable, y con capacidad de sobra para cualquier proyecto o juego de nueva generación.

Lo instale en una laptop HP que traía un ssd con Optane de menor capacidad, hubo un gran cambio en el desempeño del equipo. La instalación fue relativamente sencilla y no hubo problemas para instalar Windows 11. Es una gran opción para actualizar el hardware de un equipo y más si está en oferta, como fue mi caso.
