WD_BLACK SN770 2TB NVMe M.2 SSD Review: The Sweet Spot for Gen4 Speed and Value

I remember the exact moment I knew my old storage setup had to go. I was deep into a session of a sprawling open-world RPG, poised for a critical boss fight. My teammates were already in, shouting strategies over Discord, but I was stuck, staring at a progress bar that seemed to mock my very existence. By the time my system finally loaded the arena, the fight was over, and the precious loot was gone. That feeling of being left behind, not by skill but by hardware, is infuriating. In today’s world of massive game installations, high-resolution textures, and seamless worlds, a slow drive isn’t just an inconvenience; it’s a bottleneck that can ruin your immersion, cripple your productivity, and leave you feeling perpetually one step behind. Upgrading isn’t just about speed; it’s about reclaiming your time and ensuring your PC can keep up with your ambitions.

What to Consider Before Buying a Solid State Drive

A Solid State Drive is more than just an item; it’s a key solution for transforming your computer’s responsiveness. Unlike traditional Hard Disk Drives (HDDs) with their spinning platters and moving read/write heads, an SSD uses flash memory, allowing for near-instantaneous access to data. This translates to dramatically faster boot times, quicker application launches, and, most importantly for our purposes, drastically reduced game loading screens. The primary benefit is the elimination of waiting. By migrating your operating system and most-used applications to an SSD, you fundamentally change your day-to-day interaction with your machine, making everything feel snappier and more fluid. For gamers, this means less time staring at loading tips and more time in the action.

The ideal customer for a high-performance NVMe SSD like this is someone facing the frustrating lag of an older system. This includes gamers looking to minimise stutter and load times, content creators working with large video or photo files, and general power users who want a seamless, wait-free experience. However, this type of drive might not be suitable for those who only use their computer for basic web browsing and email, as the performance benefits would be less noticeable. It’s also not the best choice for users with very old motherboards that lack an M.2 slot. In those cases, a 2.5-inch SATA SSD would be a more compatible and cost-effective upgrade, providing a significant boost over an HDD without requiring a complete system overhaul.

Before investing, consider these crucial points in detail:

• Interface & Form Factor: Not all SSDs are created equal. The most common form factors are 2.5-inch SATA and M.2. The WD_BLACK SN770 2TB NVMe M.2 SSD uses the M.2 2280 form factor, which looks like a small stick of RAM and plugs directly into the motherboard. Crucially, it uses the NVMe protocol over a PCIe Gen4 interface, offering speeds many times faster than the older SATA interface. Before buying, you must confirm your motherboard has a compatible M.2 slot and, ideally, supports PCIe Gen4 to unlock the drive’s full potential.
• Capacity & Performance: How much space do you need? With major game titles now regularly exceeding 100GB, a 1TB drive can fill up surprisingly fast. A 2TB capacity, as offered here, provides ample breathing room for your operating system, key applications, and a healthy library of games without constant juggling. Performance is measured in sequential read/write speeds (MB/s). With up to 5,150 MB/s read and 4,850 MB/s write, this drive sits in a very competitive spot for PCIe Gen4 performance, ensuring lightning-fast data access.
• DRAM Cache & Endurance: Some high-end NVMe drives include a DRAM cache to speed up access to the drive’s mapping table. The SN770 is a DRAM-less drive, which helps keep costs down. It compensates for this by using Host Memory Buffer (HMB) technology, which allows it to use a small portion of your system’s RAM as a cache. For gaming and most consumer workloads, this is a very effective solution. Endurance, measured in Terabytes Written (TBW), indicates how much data can be written to the drive over its lifetime. Look for a high TBW rating and a long warranty (the SN770 comes with a solid 5-year warranty) for peace of mind.
• Thermal Management & Software: High-performance NVMe drives can generate significant heat. While the SN770 is designed for efficiency and doesn’t include a heatsink, many motherboards now come with their own M.2 heatsinks. If yours doesn’t, or if you’re installing it in a cramped laptop, a cheap aftermarket heatsink can be a worthwhile investment to prevent thermal throttling. Also, consider the manufacturer’s software. Western Digital provides the WD_BLACK Dashboard, a useful tool for monitoring drive health, updating firmware, and enabling a “Gaming Mode” to optimize performance.

Keeping these factors in mind, the WD_BLACK SN770 2TB NVMe M.2 SSD stands out in several areas, offering a compelling blend of speed, capacity, and value. You can explore its detailed specifications and current offers here.

While the WD_BLACK SN770 2TB NVMe M.2 SSD is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

First Impressions: Lean, Mean, and Ready to Fly

Unboxing the WD_BLACK SN770 2TB NVMe M.2 SSD is a minimalist affair. The drive comes in a small, secure box, nestled in a plastic tray. There are no frills, no extra cables, and, as many users have noted, no mounting screw—this is typically included with your motherboard, but it’s something to be aware of before you start your installation. The drive itself is incredibly compact and lightweight, adhering to the standard M.2 2280 form factor (80mm long, 22mm wide). The all-black PCB is covered by a simple sticker bearing the WD_BLACK branding. This isn’t a drive designed with flashy RGB or an integrated heatsink; its aesthetic is purely functional. This simplicity is actually a plus, ensuring maximum compatibility with laptops and motherboards that have their own integrated cooling solutions. Picking it up, you’re struck by how much power is packed into such a tiny component. It feels like holding the key to a much faster, more responsive machine.

Deep Dive: Unleashing the SN770’s True Potential

On paper, the specifications are impressive. But specs only tell half the story. The real test is how the WD_BLACK SN770 2TB NVMe M.2 SSD performs under the pressure of real-world use, from installation and setup to gruelling gaming sessions and demanding productivity tasks. We put it through its paces to see if this drive truly delivers on its promise of high-speed performance for the masses.

Installation and Setup: A 5-Minute Upgrade Path

For anyone who has built or upgraded a PC in the last few years, installing an M.2 drive is refreshingly simple, and the SN770 is no exception. After powering down and grounding ourselves, we located a free M.2 slot on our test bench motherboard. The drive slides into the angled connector with minimal effort, and then it’s just a matter of pressing it down flat against the motherboard and securing it with a single M.2 screw. As we and other users discovered, this screw isn’t in the box. This is standard practice, as motherboard manufacturers provide them, but it can be an annoying “gotcha” if you’ve misplaced the tiny bag of hardware that came with your board. A quick search online for an “M.2 screw kit” can solve this cheaply if needed.

Once physically installed, the system recognized it immediately in the BIOS. Booting into Windows, a quick trip to Disk Management was all it took to initialize and format the drive, making the full 2TB of space available. We then downloaded the WD_BLACK Dashboard software, a clean and intuitive utility. It provides at-a-glance health monitoring, temperature readings, and performance metrics. The most interesting feature is “Gaming Mode,” which disables the drive’s low-power states to ensure it’s always ready for maximum performance. While the real-world impact for casual gaming is debatable, for competitive players seeking every possible millisecond of advantage, it’s a welcome feature. The entire process, from opening the box to having a ready-to-use drive, took less than 10 minutes, making it one of the easiest and most impactful upgrades you can perform.

Real-World Gaming Performance: Where Seconds Feel Like an Eternity

This is where the WD_BLACK SN770 2TB NVMe M.2 SSD truly shines. We cloned our game library over and immediately started testing. The first test was booting into a game like *Battlefield 2042*, a title one user specifically mentioned. On our old SATA SSD, loading into a 128-player Conquest match could take upwards of 45-60 seconds, often meaning we’d miss the initial vehicle rush. With the SN770, we were on the deployment screen in under 15 seconds. This confirms the user’s experience of the game loading “x15 times faster” than an old HDD—the difference is genuinely night and day. The advantage of being one of the first to load into a match cannot be overstated.

We saw similar results across the board. In *Cyberpunk 2077*, fast-travel points became virtually instantaneous, preserving the immersive flow of exploring Night City. Large open-world games that frequently stream assets from the drive, which can cause stuttering on slower storage, felt noticeably smoother. There were no jarring pauses as the game struggled to load new textures or models when driving at high speed. The advertised read speed of 5,150 MB/s isn’t just a benchmark number; it translates directly into a more fluid and responsive gaming experience. Even PS5 users have reported excellent results, with one noting the console detected speeds of 5132 MB/s, well above Sony’s minimum requirements, making it a fantastic and cost-effective storage expansion. If you’re looking to eliminate loading screens and get into your games faster, this drive is an absolutely game-changing upgrade.

Beyond Gaming: A Comprehensive System Accelerator

While “Gaming” is in its name, the benefits of the SN770 extend far beyond the virtual battlefield. We designated it as our primary boot drive, and the results were stark. A cold boot into the Windows 11 desktop took a mere 8 seconds. Everyday applications that used to take a moment to load—Chrome with dozens of tabs, Spotify, Discord—now opened instantly. The entire operating system just feels more alive and responsive.

Where the performance really makes a difference is in content creation and productivity. We tested it by transferring a 50GB folder of 4K video files from another NVMe drive. The transfer completed in under 20 seconds, a task that would have taken several minutes on a SATA SSD and an eternity on an HDD. When editing video in Adobe Premiere Pro, scrubbing through the timeline was buttery smooth, with no dropped frames or lag, even with unrendered 4K footage. For anyone who works with large files, whether they’re a video editor, photographer, or software developer, the time saved by the SN770’s rapid read and write speeds adds up significantly over the course of a project. It proves that this drive isn’t a one-trick pony; it’s a powerful all-around performer that accelerates every aspect of your PC usage.

Thermals and Efficiency: Cool, Calm, and Collected

High speed can often mean high heat, which can lead to thermal throttling and reduced performance. Given that the WD_BLACK SN770 2TB NVMe M.2 SSD is a DRAM-less drive without a built-in heatsink, we were keenly interested in its thermal performance. Western Digital’s design focuses on power efficiency, which in turn helps reduce heat output. During our testing, which included extended gaming sessions and large file transfers, the drive performed admirably. Under a typical gaming load, temperatures monitored via the WD_BLACK Dashboard hovered around a very reasonable 50-55°C when installed under our motherboard’s stock heatsink.

We then ran a sustained benchmark test to push it to its limits. Even then, the temperature peaked at around 70°C, staying well below the throttling threshold. This confirms what one user noted as a “pleasant surprise”: “Heat buildup is minimal, even during long gaming sessions.” For most desktop PC users, especially those with decent case airflow or a motherboard heatsink, overheating will not be an issue. For those planning to install it in a thermally constrained environment like a thin-and-light laptop or a PS5 without adding a third-party cooler, an aftermarket M.2 heatsink is a wise and inexpensive precaution, as one reviewer rightly recommended. The drive’s efficiency is a key strength, allowing it to deliver sustained performance without turning into a miniature furnace.

What Other Users Are Saying

Our positive experience is broadly echoed by the user community. The overwhelming sentiment is that the WD_BLACK SN770 2TB NVMe M.2 SSD delivers exceptional performance for its price. Many, like one user who upgraded a Samsung Book 2 laptop, praise the straightforward installation and immediate system recognition. Another reviewer, who knowingly installed it in an older PCIe Gen3 slot, was still thrilled to see speeds maxing out their motherboard’s capabilities, stating, “I’m good. Ah.. the vanity.” This highlights the drive’s excellent backward compatibility and its value even for those not on the latest platforms.

However, the feedback isn’t universally perfect. The most common complaint, which we also noted, is the lack of an included M.2 mounting screw. While it’s a minor annoyance, it can be a frustrating roadblock for less experienced builders. One user summed it up perfectly: “a bit annoying considering how much you spending buying it in the first place.” We also saw isolated reports of poor delivery experiences, with one user receiving opened boxes and another a broken item. While these are fulfillment issues rather than product defects, they are part of the overall buying experience for some. Finally, a small number of users noted write speeds slightly below their expectations, though they conceded that it’s unnoticeable in day-to-day use.

How Does the WD_BLACK SN770 2TB Compare to the Alternatives?
