Today I will be reviewing the Mushkin Gamma 1TB M.2 2280 PCIe Gen4 x4 SSD. Much like everything else we rate SSD’s by speed. The faster the better of course. Unlike a lot of other devices we cant overclock these types of devices, not yet anyways. You just need to make sure you have a PCIe Gen4 slot to get the full potential of this drive. With a rated speed of 7150MB/s this drive is among just a handful of other drives that are going to be rated at these speeds. Right off the bat this drive has the capabilities to be one of the fastest drives you can get your hands on.  This drive is equipped with the new Phison E18 controller and the controller is supposed to be capable of some amazing transfer speeds. We will surely find out exactly what we can get out of this drive when we throw some benchmarks at it. Having a drive capable of transferring your files at a moments notice is becoming more and more of a necessity rather than a luxury. The faster you move these files is time saved and we all know time is money. Having a faster drive is going to speed that very thing you spend so much time on. With a faster drive you will be able to load files faster, move files faster, and accomplish more in a days time than you ever did before. Just think about it, if you are upgrading from a Gen3 you are essentially cutting this wait time in half. So keep scrolling and lets see all of the details of this drive and on the next few pages we will cover all the results from testing.

Let’s move to the next page to take a look at the Mushkin Gamma 1TB M.2 2280 PCIe Gen4 x4 SSD Packaging and Contents.




The Mushkin Gamma 1TB M.2 2280 PCIe Gen4 x4 SSD will show up being housed in a plastic package that is held closed with your typical push in tabs. On the back you will see a few features of the SSD along with some manufacturing information. The package will have no issue keeping your drive safe while its in transport. The front does state Gen3 x4 but It is a Gen4 x4 drive as you can see that clearly labeled on the back. Could be confusing but rest assured it is a Gen4 device.

Now let us take a closer look at the Mushkin Gamma 1TB M.2 2280 PCIe Gen4 x4 SSD itself!

A Closer Look and Testing

unnamed file 1493

Phison designed the new E18 from the ground up on the efficient TSMC 12nm process node. This provides SSD manufacturers with a state-of-the-art controller solution in an increasingly competitive field.  The controller utilizes Phison’s proprietary CoXProcessor 2.0 technology, an innovative SSD architecture that enables E18 to deliver exceptional performance and power efficiency.  Phison architecture is also primed for AI-assisted storage, where its distributed architecture uses many small cores to perform the workload in parallel.  The E18 is ideal for gamers, content creators, and computing enthusiasts, which demand the best experience. This ultra-low latency is possible only with NVMe SSDs.

unnamed file 1496

The E18 maximizes use of the available bandwidth of PCIe 4.0 to improve sequential read performance up to 7.4GB/s and write performance to 7.0GB/s, making E18 the only solution in the market to break the 7.0GB/s on both read and write access. When fully utilized, the eight-channel E18 delivers up to 1 million IOPS and scales to a massive 8TB capacity.

PCMark 10 Results with real-world relevance

  • PCMark 10 Storage Benchmarks produce an overall score as a measure of drive performance. Comparing devices is as simple as comparing scores. The tests also measure and report the bandwidth and average access time performance for the drive.
  • Each test uses traces recorded while performing real-world tasks such as booting Windows 10, starting applications such as Adobe Photoshop and Illustrator, working with applications such as Microsoft Excel and PowerPoint, and copying several large files and many small files.
  • Unlike other synthetic storage tests, this focus on real-world activities enables PCMark 10 to show meaningful differences between the latest, high-performance storage technologies.
  • PCMark 10 Storage Benchmarks help professional users relate manufacturers’ technical specifications to practical real-world performance with tests that are easy to set up and run.
  • You can compare up to four results in the PCMark 10 app, or export your results to Microsoft Excel for more detailed analysis.


The Quick System Drive Benchmark is a shorter test with a smaller set of less demanding real-world traces. You can use this benchmark to test smaller system drives that are unable to run the Full System Drive benchmark.

The Data Drive Benchmark is designed to test drives that are used for storing files rather than applications. You can also use this test with NAS drives, USB sticks, memory cards, and other external storage devices.

Well there we have it, the Mushkin Gamma 1TB M.2 2280 PCIe Gen4 x4 SSD, now lets move on to the last page and read a little on the Conclusion and Verdict.


unnamed file 1522

Conclusion and Verdict

As you saw in the test results the drive easily reaches read speeds of 7000MB/s. This is an insane transfer speed with out any outside controller. This is all packed into a small M.2. I was extremely satisfied to only see a max temp of 55 degrees Celsius while running all these test back to back. This was recorded utilizing the heatsink from the motherboard. This is probably going to be the most common way all of will install this drive. If your motherboard doesn’t have heatsink I don’t see temperatures being an issue either way. Regardless these temps are very acceptable. Moving data at these speeds, heat can become something to watch but no worries here. You don’t need to hassle with an external heatsink that come pre-applied to a lot of drives you find in this speed range. Something else I like is the built in protections from the Mushkin Enhanced Data-protection Suite (MEDS). This isn’t something you download and use as an utility but it is built-in LDPC ECC that provides the most-powerful data correction level, End-to-end data path protection, SmartECC, Thermals. Encryption, and an Enhanced power management that will keep those temps lower. All of these features are very import to the longevity to your drive. On a lighter note I like tag line Gamma and the red color scheme. If you are a Hulk fan then you already know where I am going with this. Turn you storage capabilities into something Hulk like by adding a little Gamma to it!

You aren’t going to find a drive much cheaper than this one, at similar speeds. The test speeds speak for themselves. They are some of the fastest speeds I have tested to date. And you are only going to find a handful of drives capable of something faster. We have waited a little while for a Gen4 x4 from Mushkin but for the wait is worth it after seeing the capabilities of this device. They also have one other featuring the Phison E16 called the Delta.
