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


SSD testing at TSSDR differs slightly, depending on whether we are looking at consumer or enterprise storage media. For our WD Blue SN500 NVMe M.2 SSD testing today, our goal is to test in a system that has been optimized with our SSD Optimization Guide. To see the best performance possible, the CPU C states have been disabled, C1E support has been disabled, and Enhanced Intel SpeedStep Technology (EIST) has been disabled. Benchmarks for client testing are also benchmarks with a fresh drive so, not only can we verify that manufacturer specifications are in line but also, so those buying pre-built systems with the SN500 can replicate our tests to confirm that they have an SSD that is top-notch. We even provide links to most of the benchmarks used in the report.


The components of this Test Bench are detailed below.  All hardware is linked for purchase and product sales may be reached by a simple click on the individual item. As well, the title is linked back to the individual build article where performance testing can be validated.

The software in use for today’s analysis is typical of many of our reviews and consists of Crystal Disk Info, ATTO Disk Benchmark, Crystal Disk Mark, AS SSD, Anvil’s Storage Utilities, AJA, PCMark Vantage, TxBench, PCMark 8, as well as true data testing. Our selection of software allows each to build on the last and to provide validation to results already obtained.


Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.


Crystal Disk Info validates that our SSD is running in PCIe 3.0 x2 (two lane), and also that NVMe 1.3 protocol is in use.


ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.


We always start our testing with ATTO as this software is that typically used by manufacturers to determine their listed specifications for data throughput.  As we can see, results of 1750MB/s read and 1460MB/s write are right on the money.

    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 ?
