Patriot Magnum2 USB 3.1 Flash Drive Review (256GB)


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.

When testing the Patriot Supersonic Magnum2 USB 3.1 Flash Drive similar to how the manufacturer would have attained their specifications, we can reach listed specs with Crystal DiskMark.  Some may wonder why we have omitted the remainder of the tests in this software program and the reason is that it we typically do such as it takes much longer to complete the tests.  The other results are not that good quite frankly, and 4k transfer speeds are very low.  This flash drive, as with most, is intended for the transfer of larger files to include media such as music, movies and pictures and these are the speeds that can be realized when utilizing the drive for its intended use.


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.

Similar results were seen in AS SSD which were quite surprising as AS SSD would definitely be the first to identify the lower performance of low quality memory and workmanship.  We wanted to include the AS SSD Copy Benchmark as it is great validation when we speak of how long it takes smaller files to transfer to and from the drive as the low 4K transfer speeds are so low.

In providing our final review of the Patriot Magnum2, we need to remind that the purpose of this flash drive, as well as 99% of flash drives on the market today, is to transfer larger data files such as pictures, movies and music. This is where see the incredible performance this drive contains.

    Just how susceptible are these devices to thermal throttling, especially with a lot of small files?

      Can’t speak for this device specifically (although it most likely uses PS2251-08), but i do have another phison based drive and it get quite hot during transfer.

    So USB 3.1 Gen 1 is like portable SSD from SanDisk or Samsung with read speeds of 450MB/s? so when are we expecting to get USB 3.1 Gen 2 external storage with speeds of 10Gb/s

    • blank

      Much like we saw with Thunderbolt, I believe there will be a hardware transition period where manufacturers will still rely on USB 3.1 Gen 1 for affordability. Once we see type C connectors become commonplace, so will the faster speeds. Just my 2 cents.

    Did 4K performance improve or regress versus the previous generation Patriot Supersonic Magnum (Gen 1) thumbdrives?

    Plenty of folks are using these on a daily basis with small files (sometimes even as primary storage). So with these new Gen 2 drives, it would be interesting to know if Patriot has managed to keep (or improve upon) the previous good performance of the Gen 1 drives. Especially with small files.

    The Gen2 increase to 512GB will be welcome as long as they can maintain performance and reliability. Just look at the disastrous reliability that some folks have experienced when trying to upgrade from Gen 1 Patriot Supersonic Magnum thumbdrives (256GB and below) to the 512GB Corsair Flash Voyager GS.

    Users experienced some DOAs and premature deaths on those Corsairs. Also, performance was noticeably laggy on the Corsair 512GB.

    Lets hope Patriot managed to keep it right (and not regress) on this 512GB product.

    As for the assertion that big thumb drives are primarily used for very large files, I’m not so sure. I think most people use them with files sets that include a wide variety of files sizes.

    One practical way to test usability is to see if there are noticeable delays when opening various files types. For three years, I’ve used the Gen 1 drives as primary storage, travel backups, and giveaways to family (I currently have a dozen, evenly split between the 256GB capacity version and smaller versions). They let you open large spreadsheets in less than a second. With the Gen 1 drives you can navigate, enter data, copy, paste, etc., with very little delay.

    Another practical way to test is to see how they handle copy operations. With the Gen 1 drives, file and folder creation and copy times are acceptable, though not nearly as good as an internal SSD.

    Low quality thumbdrives on the other hand, will quickly gouge chunks of time out of your daily productivity workflow. They feel like quicksand has invaded your drive.

    So which is it… are these usable for daily workflow?

    Or just draggy dogs?

      In comparing this to Gen 1, our tests were conducted with 0Fill whereas here they are not. This show a marked improvement in this fact alone, however, looking at the 4K results I recall 43/29 which is significantly better than last Gen regardless. We are trying to get our hands on the drive again for further testing.

        Thanks heaps for going to the trouble to try to get the drive again. I hope it works out.

        I found some old numbers that showed 36/2 on the older Gen 1 Patriot Magnums. If this newer drive can do 40/20 (or better) then that would be a significant improvement indeed.

        Obviously 40/20 doesn’t grab headlines, but folks should try to understand that throwing 4K files at any drive is like asking the drive to chip away at bomb-shelter concrete… it’s hard work.

        Any thumbdrive that can do it smoothly and allow your workflow to stay productive is exceptional. Hopefully that will be the case with this newer Patriot Supersonic Magnum2 model.
