What Are SSD Sequential Read Write Speeds?
Think of your SSD as a digital library. "Sequential read speed" is how fast it can read a book (a large file like a game level or 4K video) from start to finish, page by page. "Sequential write speed" is how fast it can write that book down in one continuous go, like when you're installing a game or saving a big video project.
Measured in megabytes per second (MB/s), higher numbers mean faster performance for these specific, large-file tasks. It's the headline spec you see on the box, and for good reason.

Why Sequential Performance Matters for Gamers and Creators
For South African gamers, high sequential read speeds are critical. When you're loading into a massive open-world map in Cyberpunk 2077 or jumping into a new match in Warzone, the game is reading huge chunks of data. A drive with blistering SSD sequential read write speeds cuts those loading times down dramatically. You spend less time waiting and more time playing.
Content creators feel it, too. Editing high-resolution video, rendering complex 3D models, or transferring massive project files all rely heavily on fast sequential performance. A drive like the KLEVV CRAS C925G 1TB Gen4 NVMe SSD can slash render times, making your workflow significantly more efficient. ✨
Don't Bottleneck Your Speed! 🔧
Before you buy a super-fast Gen4 or Gen5 SSD, double-check your motherboard's manual or product page. Your M.2 slot must support the same PCIe generation to unlock the drive's maximum sequential read write speeds. Plugging a Gen4 drive into a Gen3 slot will limit its performance to Gen3 levels. It'll work, but you'll be leaving a lot of speed on the table!
Decoding the Numbers: Gen3 vs. Gen4 vs. Gen5
The "Gen" refers to the generation of the PCIe interface your SSD uses. Each new generation roughly doubles the potential speed.
- PCIe Gen3: The old standard, topping out around 3,500 MB/s. Still great for general use and budget builds.
- PCIe Gen4: The current sweet spot, hitting speeds of 7,000 MB/s or more. Ideal for modern gaming rigs and workstations.
- PCIe Gen5: The new frontier, pushing past 12,000 MB/s. It's bleeding-edge tech for those who demand absolute maximum performance.
As technology evolves, you can count on trusted brands like Klevv South Africa to deliver reliable performance across these generations, ensuring you get the speed you pay for.

Is Bigger Always Better? Sequential vs. Random Speeds
So, should you just buy the drive with the highest sequential numbers? Not necessarily. While sequential speeds are vital for large files, your PC's overall snappiness—like booting up Windows or launching a browser—depends more on random read/write speeds.
Random speeds measure how quickly the drive can access small, scattered bits of data. Think of it as flicking to random pages in a book instead of reading it cover to cover. For a balanced, high-performance system, you need a drive that does both well. When you browse our full range of SSDs, you'll see a variety of options tailored for different needs and budgets.
Ultimately, understanding SSD sequential read write speeds empowers you to make a smarter choice, ensuring your next upgrade delivers the real-world performance boost you're looking for. ⚡
Ready to Eliminate Loading Screens? Understanding SSD speeds is the first step. The next is finding the perfect drive for your rig and budget. Whether you're a competitive gamer or a content creator, the right SSD makes all the difference. Explore our massive range of SSDs and find the perfect drive to conquer your world.
It measures how fast an SSD accesses large files, like movies or game ISOs, stored contiguously. Higher speeds mean faster file transfers and loading of large assets.
While sequential speed helps load large levels, random read speed is often more vital for loading many small texture files and general OS responsiveness.
For Gen4 NVMe drives, speeds over 5000 MB/s are considered excellent. For standard SATA SSDs, the interface limits performance to around 500 MB/s.
Generally, no. High sequential read write speeds significantly reduce load times but rarely increase actual in-game FPS, which relies more on your GPU and CPU.
You can use standard benchmarking software like CrystalDiskMark or AS SSD Benchmark to accurately test both sequential and random performance metrics.
Writing data requires more complex operations (erasing and programming cells) than reading, often resulting in lower sequential write speeds compared to reads.
