We’ve all been there. That once-zippy laptop or trusty desktop computer now takes an eternity to boot up. Launching a simple web browser feels like a chore, and the constant whirring and clicking of the old mechanical hard drive is a painful reminder of its age. I remember wrestling with an old family PC, a machine relegated to the corner of the room for simple tasks, that had become almost unusable. Booting into Windows was a five-minute affair, and opening a spreadsheet would send the hard drive activity light into a frantic, non-stop flicker. This isn’t just an inconvenience; it’s a productivity killer that can make you want to throw the entire machine out the window. The problem is, that old computer might still have a perfectly good CPU and enough RAM for daily tasks. The true bottleneck, the anchor dragging it down, is its slow, spinning-platter hard disk drive (HDD).

What to Consider Before Buying an Internal Solid State Drive
An Internal Solid State Drive is more than just a storage device; it’s a key solution for rejuvenating sluggish computers and unlocking their true potential. Unlike traditional HDDs that rely on spinning magnetic platters and a mechanical read/write arm, SSDs use flash memory—similar to a USB drive, but vastly faster and more robust. This fundamental difference solves the core problems of slow boot times, lagging application launches, and system-wide unresponsiveness. The main benefits are a dramatic increase in speed, silent operation due to the lack of moving parts, improved durability against drops and shocks, and lower power consumption, which can even extend laptop battery life.
The ideal customer for a budget-friendly SATA SSD like this is someone facing the exact scenario described above: you have an older desktop or laptop with a SATA interface that’s become painfully slow. You’re looking for the single most cost-effective upgrade to make the machine feel new again for tasks like web browsing, office work, or light media consumption. It’s a perfect fit for reviving a secondary “garage PC,” building a low-power media server, or simply extending the life of a computer that doesn’t warrant a major investment. However, this type of drive might not be suitable for those who are building a high-end gaming rig, editing 4K video, or working with massive datasets. For those users, the superior speeds of an NVMe SSD are essential. Similarly, if you are storing irreplaceable data without a robust backup system, the potential reliability issues of an ultra-budget drive might be a risk not worth taking.
Before investing, consider these crucial points in detail:
- Dimensions & Space: The Bliksem KD650 512GB SATA III SSD uses the standard 2.5-inch form factor with a 7mm thickness. This is the most common size for laptop hard drives and is also easily mountable in virtually any desktop case, sometimes with a simple adapter bracket. Before buying, you should confirm your device has a 2.5-inch drive bay and a standard SATA connection port available.
- Capacity/Performance: With 512GB of storage, this drive hits a sweet spot for many users, offering enough space for the operating system, a suite of essential applications, and a good number of games or files. Performance-wise, it utilizes the SATA III interface, which maxes out at around 600 MB/s. While significantly faster than any HDD, it is not as fast as the newer NVMe interface, which can be 5 to 10 times faster. For its intended purpose of replacing an HDD, its performance is transformative.
- Materials & Durability: The drive is housed in a very lightweight plastic casing. While this doesn’t impact performance, it can feel less premium than the metal enclosures of more expensive SSDs. The real durability of an SSD comes from its lack of moving parts, making it highly resistant to physical shock and vibration. However, the longevity of an SSD is determined by the quality of its NAND flash memory and controller, which can be a point of concern with lesser-known brands.
- Ease of Use & Maintenance: Physically installing a 2.5-inch SATA drive is incredibly straightforward. It’s a simple matter of connecting the SATA power and data cables. The software side can require either cloning your old drive or performing a fresh installation of your operating system. Some users have noted potential formatting hurdles, so being prepared to initialize and format the drive in Disk Management is a good idea.
Keeping these factors in mind, the Bliksem KD650 512GB SATA III SSD stands out in several areas, particularly its aggressive pricing. You can explore its detailed specifications and current offers here.

Unboxing the Bliksem KD650: A No-Frills First Encounter
Our experience with the arrival of the Bliksem KD650 512GB SATA III SSD was, in a word, basic. The drive arrived in a simple bubble mailer, lacking the protective plastic clamshell or rigid box that typically accompanies storage components from more established brands. Upon opening it, the first thing we noticed was the drive’s weight—or lack thereof. The all-plastic enclosure makes it feel almost hollow and incredibly light, which some users have described as feeling “cheap.” While a heavy heatsink isn’t necessary for a SATA drive of this class, the physical impression doesn’t exactly inspire confidence in its ruggedness.
The branding is simple, with a black sticker featuring the Bliksem logo and model information. There are no accessories in the package—no SATA cable, no mounting screws, and no software for cloning. This is purely a bare-bones product, which is understandable given its rock-bottom price point. The focus is clearly on delivering a functional drive at the lowest possible cost, and the spartan packaging and lightweight build are direct results of that philosophy. For us, it wasn’t a dealbreaker, but it’s a stark contrast to the premium unboxing experience offered by market leaders.

Performance Under the Microscope: The Bliksem KD650 in Action
A budget SSD lives and dies by one question: does it deliver a tangible, worthwhile performance boost for its low cost? With the Bliksem KD650 512GB SATA III SSD, the answer is a complicated “yes, but…” It’s a drive that exists at the absolute entry-level of the market, and our testing revealed a device with a dual personality: one of a shockingly capable speed demon for the price, and another of a questionable performer with serious reliability concerns that cannot be ignored. We dove deep into its performance, from initial installation to real-world use and the looming shadow of its reported flaws.
The Upgrade Effect: Breathing New Life into Old Hardware
Our first test was to install the Bliksem KD650 512GB SATA III SSD into its natural habitat: an aging HP Pavilion laptop from around 2014, which was equipped with a painfully slow 5400RPM mechanical hard drive. The physical installation was a breeze, taking less than five minutes to swap out the old drive. After performing a fresh installation of Windows 10, the difference was not just noticeable; it was staggering. This mirrors the experience of one user who saw their boot time plummet from over a minute to a mere 8 seconds. Our results were similar, with the laptop going from a cold boot to a usable desktop in about 12 seconds flat. This is the magic of moving from mechanical to solid-state storage.
To quantify this, we ran CrystalDiskMark, a popular storage benchmarking tool. The old HDD struggled to hit 80 MB/s in sequential read and write speeds. The Bliksem, on the other hand, immediately impressed. We recorded sequential read speeds of 495 MB/s and sequential write speeds of 440 MB/s. These figures are squarely in line with what you’d expect from a good budget SATA III SSD and remarkably close to its advertised speeds of 550/450 MB/s. For anyone coming from an HDD, this drive provides the exact jolt of performance they’re looking for. Applications that used to take 10-15 seconds to load now snap open almost instantly. The entire system feels more responsive and modern, effectively erasing years of frustrating lag.
Real-World Speed and Gaming Load Times
Synthetic benchmarks are great, but how does the drive feel in day-to-day use and for more demanding tasks like gaming? We loaded the drive with a typical software suite: Chrome with a dozen tabs, LibreOffice, and Spotify. Multitasking felt smooth, without the stutters and hangs that plagued the old HDD when multiple applications were vying for disk access. The system was simply able to fetch data fast enough to keep up with our demands.
Next, we decided to push our luck with gaming, inspired by a user who reported running modern titles on it. We installed a couple of games, including a large open-world title. While an SSD doesn’t increase your frames-per-second (FPS), it drastically cuts down on loading times. Fast-traveling across the game world, which used to trigger a 30-40 second loading screen on the HDD, was now a 5-10 second affair. Textures loaded in more quickly, reducing the distracting “pop-in” effect common when streaming game assets from a slow drive. For a casual gamer looking to reduce wait times on an older system, the Bliksem KD650 512GB SATA III SSD performs admirably. It proves that even a budget SATA drive is more than sufficient to provide a quality gaming experience, completely eliminating one of the most significant bottlenecks in modern PC gaming.
The Elephant in the Room: Reliability and Quality Control Roulette
While our initial performance tests were overwhelmingly positive for the price, we cannot ignore the significant volume of user feedback that points to a serious problem: long-term reliability. The story of the Bliksem KD650 512GB SATA III SSD is one of a gamble. You might get a fantastic, fast drive that lasts for years, as some users have. Or, you might get a dud that fails within weeks or months, taking all your data with it.
We encountered several deeply concerning reports that reflect a pattern of poor quality control. One professional PC builder who purchased a dozen of these drives on sale found the first two he tested performed as slowly as a mechanical hard drive and failed to even complete Windows updates. Another user bought six drives and had two fail within 23 days, discovering afterward that multiple drives shared the exact same serial number—a massive red flag in manufacturing. Others have reported the drive working fine for a few months before exhibiting intermittent failures, with boot times suddenly ballooning to over five minutes, followed by complete failure. Several reports mention the drive dying completely and becoming unrecoverable, stuck in a read-only or raw state.
These are not isolated incidents. The pattern suggests issues with the NAND memory, the controller, or both. This is the trade-off for the ultra-low price. While brands like Samsung or Crucial invest heavily in R&D and rigorous testing, it appears that with Bliksem, the end-user is partially responsible for the final stage of quality assurance. This makes the drive an incredibly risky proposition for use as a primary boot drive or for storing any kind of important data. Its best use case is in a non-critical system where a sudden failure would be an annoyance rather than a catastrophe.
What Other Users Are Saying
The user experience with the Bliksem KD650 512GB SATA III SSD is sharply divided, painting a picture of a product that is either a spectacular bargain or a complete failure. On the positive side, many users are thrilled with the performance-per-dollar. One happy customer noted, “I upgraded from a slow 5400rpm HDD… Where the old driver had a CrystalMark Seq score of around 78 read and 75 write, this drive achieved 499 read and 443 write! Startup time is reduced from 1 minute to 8 seconds!” Another found success using it in a more specialized role, stating, “Pretty good if you want to use it for TrueNAS or Linux; it works like a charm.”
However, the negative feedback is severe and consistent. The most damning criticism comes from experienced builders and users who have seen the drives fail prematurely. One user offered a stark warning: “AVOID THIS PRODUCT. Worked fine for about six months of light use. However, it began to experience intermittent failure… Then this SSD failed completely.” Another user’s experience was even quicker: “Moved all current games and files over to this SSD and it lasted about two weeks before it completely died. Unable to initialize, nothing on the ssd is recoverable.” This feedback highlights the gamble involved; while the initial speed is there, the longevity is a serious roll of the dice.
How Does the Bliksem KD650 Compare to the Competition?
The Bliksem KD650 512GB SATA III SSD operates in a crowded market. While its price is its main weapon, it’s crucial to see what you get by spending a little more or by choosing a different form factor for a more modern machine.
