ioSwitch Raijin M.2 NGFF PCIe SSD Review – Plextor M6e PCIe M.2 SSD Revealed With Boot Features


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.

ATTO performance highs of 738MB/s read and 583MB/s write are right up there with listed specifications, and our first look at PCIe data transfer speeds.


Crystal Disk Benchmark is used to measure read and write performance through sampling of highly compressible data (oFill/1Fill), or 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.

High sequential performance remained high and the low 4K random write speeds were adequate, although we might like to see speeds above 100MB/s become the norm.


Up until recently, AS SSD was the only benchmark created specifically for SSD testing and it uses incompressible data.  AS SSD, for the most part, gives us the ‘worst case scenario’ in SSD transfer speeds because of its use of incompressible data and many enthusiasts like to AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.

You may not see this for long (and it’s definitely not common) but you get a freebee simply for reading! Over the last little while, we have been assisting with beta testing new benchmark software called Anvil Storage Utilities which is an absolutely amazing SSD benchmarking utility. 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.

We wanted to push things a bit and see how close we could get to manufacturers IOPS specs so we pushed the read and write queue depth just a bit:

    Great review Les. So how is this product different to combining say the Plextor M.2 and one of the Bplus or M.2 Enabler cards. Do the latter cards also allow the system to boot, or is this something new that only this ioSwitch Raijin card can do?

      We tried the SSD in several cards and regardless, it will boot. We have also confirmed this to be a customized SSD that will allow it. The SSD is bootable, not the card.

        So any other generic ssd in the Asus impact motherboards onboard connector would not be bootable?

        Not quite. If the M.2 host is built into the motherboard, you can believe that they have taken this into account. This design was a custom build to ensure this SSD has very wide compatibility in systems, such as the Mac Pr desktop, which has traditionally been used by media professionals who can use this specific performance upgrade.

    Man….can’t wait for Tosh to start using the Indilinx Barefoot 3 controller now that they own Ocz…pretty sure it’ll smoke the Marvell controller they’re using. Plextor may end up the main and/or exclusive source of future BF3 based ssds…hmmm

    Hey! Very informative! Plenty of images, links, and explanations.
    Unfortunately, I cannot afford anything like this yet. Thus, having to buy an SSD, I shall go for either SATA or mSATA. I am still puzzled, though, as to which is the best choice. Which of the two will give me the highest performance?

    • blank

      mSATA and SATA SSDs will provide the same performance for the most part, however understanding your systems configuration is crucial. Many mSATA buyers have been disappointed to learn their mSATA slots on their motherboards, or in portables, was SATA 2 and not 3.

    Which motherboards allow the best performance for this concept?

    could anybody tell me if this would work on a macbook pro 2015 version?
