WD Blue SN500 M.2 NVMe SSD Review (500GB) – Saying Goodbye to SATA


Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.

Crystal DiskMark expands on things just a bit and these results are great for any PCIe 3.0 two lane SSD.


The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.The AS SSD results aren’t as appealing as we might like to see but do get a first look at read and write IOPS which appear to be in the general ball park of listed specs.





AS SSD results are just a bit lower as is the normal result, and this software also gives us our first look at IOPS.  Listed specs are 275K read and 300K write, whereas we achieved 266K read and 327K write at low 4K random disk access.


Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.



The AJA Video Systems Disk Test is relatively new to our testing and tests the transfer speed of video files with different resolutions and Codec.

    That’s great news.
    FYI, spell check is wonderful but it just can not beat a good read thru by your mom.

    “The difference between this and most M.2 SSDs today is that it is uses two PCIe lanes vice four.”
    *VERSUS – not vice

    ” This cuts performance just about in have from enthusiast SSDs but that applies just the same to the price point.”
    *HALF – not have

      Love guys like you…you reassure me that I still have someone reading my work.

      The definition of ‘vice’ in Merriam-Webster is “rather than…as in ‘two PCIe lanes vice four’ as I said. Although, ‘versus’ could be considered, I would term it an odd choice as most people define ‘versus’ as one thing against another, and not one thing rather than the other.

      Funny to read this after finishing an otherwise technical (and in general well written) article. Made my day. 🙂

    I seek a 256gb ssd to put in an enclosure with JMS583 controller. I seek the fastest ssd and the coolest. with a price around 50 euros top. It is for windows to go and booting on various ISOs which will be put on the SSD.

    I see that there is this new SN500 and the kingston-a1000. Are they the same in terms of speed, heat, and relevancy for my usage ?
