Preface
Western Digital has long been the dominant leader in the hard drive market. Whether in China or overseas, it’s the top choice for most users. Many gaming laptops and high-end desktop PCs tend to favor the WD SN580 NVMe. With its blazing-fast read speed of 4000 MB/s and capacity of up to 2 TB, the SN580 truly reigns supreme as one of the best NVMe SSD options available.
So, aren’t you curious about how it actually performs? Below, Lanco will test a still-young SN580 that has already written and read over 25 TB of data.
Test Screenshot 
Because the SSD’s read/write performance is so impressive, an 8 GiB data test was run. The result? A stunning 4220 MB/s read speed — practically unmatched in today’s market.
When it comes to reading and writing small files, its performance is comparable to a mechanical hard drive reading large files — and in some cases, even faster.
Issues / Tips
When writing a large amount of data in a single operation, the SN580 can heat up quickly if you don’t have a heatsink installed. For example, Lanco once allocated 500 GB of space to a VMware virtual machine — within about one minute, the temperature shot up to 83–84 °C.
If you don’t want your SN580 to wear out prematurely, make sure to use a heatsink!
However, for everyday gaming or office tasks, a heatsink isn’t necessary.
Cost Performance
There are now NVMe SSDs with read/write speeds of up to 7000 MB/s, but the SN580 still offers outstanding value for money. It remains the undisputed #1 choice for gamers in 2024.
Now that we’ve entered 2025, let’s hope high-speed SSD prices keep coming down!
