In today’s standards for high-speed storage devices, SSDs that uses the NVMe interface take the crown. As of now, SSDs available in the market is still far away from hitting the NVMe interface limit. That’s why NVMe SSDs are getting faster than ever while maintaining at a reasonable price. The Plextor M9PeG is one of those SSDs that has great performance with a reasonable price.

The Plextor M9Pe series of SSDs come in the variations as per mentioned here. The Plextor M9PeG that we have here is in the M.2 2280 form factor with a heatsink included and with 512GB in capacity. We’ve also reviewed the M9PeY variant that comes with a PCIe riser card and a heatsink.

As we’ve already looked at a few Plextor NVMe SSDs before, how does Plextor’s latest generation of NVMe SSD perform?


When it comes to packaging, the Plextor M9PeG is fairly simple. Its colors and general aesthetics are adapted from the M9PeY variant that has a larger box. Of course, Plextor still cramped all of the crucial information on the packaging itself.

With a smaller box, Plextor still include a full specs list. Though, it’s a little difficult to read.

Opening up the box reveals the Plextor M9PeG itself with a screw, seated on a larger piece of plastic clam shell to provide protection. It’s great that Plextor included a screw too as many other M.2 SSDs don’t.

It’s still an M.2 2280 after all – there’s nothing much that can be done in terms of design other than the heatsink. Plextor opted for the same symmetrical aerofoil design which actually helps in terms of dissipating heat to a larger surface area.

The PCB itself is green in color but that’s nothing to worry about since there’s a huge heatsink covering it up anyway – but a little bit of it does peek out. There is a warranty sticker that wraps around the PCB to the side of the heatsink. If this seal is broken then say bye-bye to your 5-years warranty.

It’s also worth noting that the Plextor M9PeG 512GB variant is only utilizing one side of the PCB.

Peeking inside, we can see that the heatsink is quite thin and is in contact with the chips through a large piece of thermal pad.

Compared to its brethren with a PCIe riser, the Plextor M9PeG is rather… not so flashy when it comes to the physical design and features. No RGB or fancy lights – just a heatsink with Plextor’s logo in red.


SSD speeds vary from capacity to capacity, and the one we have here is the 512GB variant. From the specs, we can see that the Plextor M9PeG will perform admirably – if the controller holds up.

We first used Crystal Disk Mark as usual – filled it with some data and then ran the benchmark with random fill and also 0fill. There is a noticeable performance difference for random fill data but not really a significant one.

On ATTO benchmark that uses compressible data, we can see that the speed plateaus starting from 1MB file size.

With the worst case scenario, the Plextor M9PeG can handle both incompressible stock and fill tests without much variation. At such dire situations, the speed is heavily different from the advertised read/write maximums.

Real use case scenario

As mentioned in our M9PeY review here, it’s actually the same use case as the M9PeG. Both are of the same controllers and same NAND flash chips – but packaged in a different way. With just a M.2 2280 stick and a fairly small heatsink on it, the Plextor M9PeG can indeed save space. Our friends did write about an article on why M.2 SSDs are more convenient, and we have to agree since mini-ITX builds can leverage on the lack of need for cables.

With such a speedy storage, the M9PeG is never going to disappoint at demanding tasks like video scrubbing on Premiere Pro. I did the same for the M9PeY, and I have to say that the video editing experience is one of the most seamless one that I’ve had. I oftentimes overlay 3 high bitrate videos together, and the M9Pe series of SSDs in general, is able to handle it.

Temperature test

Remember when we talked about how NVMe SSDs can thermal throttle but mitigated with the help of a large air cooler? Given that there’s a heatsink on the Plextor M9PeG, heat does transfer out much better but you’ll still need airflow.

We used an open air testbench this time around with only ambient air circulation – and the Plextor M9PeY managed to keep things within 50°C. It’s a surprise that the having a heatsink managed to improve that much in terms of temperature.

Wrapping up the Plextor M9PeG review

In short, the Plextor M9PeG is commendable for the performance it offers. In terms of aesthetics, there’s really nothing much to say about it – the black heatsink with a red logo is good enough for me. Newegg is currently selling the Plextor M9PeG  512GB at just USD $219.99. In direct conversion, it costs less than RM900!

For the performance it offers and the price Plextor is asking for, the M9PeG is definitely one of the highest price-performance ratio SSD in the market. I highly recommend this M.2 NVMe SSD for those who are looking for performance while maintaining a thick-ish wallet. Content creators – videos especially, will absolutely love the Plextor M9PeG, though it’s a bit overkill. But hey – it’s always good to overkill than to underkill.
