Crucial P5 Plus (with Heatsink) Review (vs. Samsung 980 PRO): A Solid Contender

Share what you're reading!

Micron's latest PCIe 4.0 NVMe solid-state drive, the Crucial P5 Plus, is a formidable rival to the Samsung 980 PRO. It delivered excellent performance in my tests and long-term real-world usage, even with an older PCIe 3.0 motherboard.

In early 2023, Micron added the heatsink version of the drive. The P5 Plus likely will be the company's last PCIe 4.0 NVMe considering it launched the PCIe 5.0 drive, the Crucial T700, earlier in 2023.

That, plus the current friendly street price—$43, $50, and $98 for 500GB, 1TB, and 2TB, respectively (add $10 for the heatsink version)—means the Crucial P5 Plus is a clear winner in the pricing contest. The two deliver about the same performance and have similar features.

If you're looking for a mainstream PCIe 4.0 NVMe SSD, the Crucial P5 Plus is an easy recommendation. Get one today!

Dong's note: I first published this post on  August 4, 2021, when the SSD was launched as a new piece and upgraded to a full review on August 13, 2021, after thorough hands-on testing. On July 26, 2023, I updated it with information on the heatsink version.

Like most high-end NVMe SSDs, the P5 Plus takes the standard 2280 NVMe design—it's 80mm long and 22mm wide.

Apart from PCIe 4.0, the drive also works with a PCIe Gen 3 M.2 slot, which is still popular in most computers, and the new PCIe 5.0 slot available in the latest motherboards.

Useful features and software, similarly modest endurance

According to Micron, the Crucial P5 Plus' advanced features include:

  • Dynamic write acceleration
  • Redundant array of independent NAND (RAIN)
  • Multistep data integrity algorithm
  • Adaptive thermal protection
  • Integrated power loss immunity
  • Active garbage collection & TRIM support
  • Self-monitoring and reporting technology (SMART)
  • Error correction code (ECC)
  • NVMe autonomous power state transition (APST)
  • Full-drive encryption capable (TCG OPAL 2.0)

To manage all those, the Crucial P5 Plus comes with the familiar Crucial Storage Executive software toolbox comparable to the Samsung Magician of the 980 PRO.

The software is useful for checking the status, firmware updates, overprovisioning/cache management, and other tools.

The Crucial Storage Executive software is an excellent toolbox for the P5 Plus.

On top of that, the Crucial P5 Plus shares the same endurance level as the Samsung 980 PRO.

Specifically, if you write some 100GB, which is a lot of data, a day and do that every day to the 1TB version, it’ll take some 15 years to wear the drive out. If you use the 500GB or 2TB versions, you'd need 7.5 years and 30 years, respectively.

And those are a very long time—generally, you won't need to worry about wearing the drive out. However, compared to many PCIe 3.0 drives, the P5 Plus' endurance is still modest. The Samsung 970 PRO, for example, has twice the longevity.

But what the Crucial P5 Plus lacks in endurance if at all, it more than makes up in performance, which is the most important thing anyway.

Micron Crucial P5 Plus: Excellent PCIe 4.0 performance

I initially tested the naked version of the Micron Crucial P5 Plus with PCIe 3.0 and PCIe 4.0 motherboards. Later on, I tried the heatsink version also with PCIe 5.0, and in all cases, the drive excelled.

And in my combined test, where the drive performed reading and writing simultaneously, it almost topped the charts when working with a PCIe 5.0 motherboard, trailing behind only the T700. Its performances on the lower PCIe gens were also excellent compared to its peers.

Compared to the Samsung 980 Pro, the Crucial P5 Plus had a pricing advantage. In real-world usage, I found no differences between the two. Both delivered excellent storage experiences. For example, my test host computers—PCIe 4.0 and PCIe 3.0 machines—took just seconds to boot up, and all apps launched quickly.

Here's the heatsink Crucial P5 Plus next to the Crucial T700 vs. its naked version next to a Silicon Power XS70.

In fact, on the same PCIe 5.0 motherboard, the P5 Plus felt similar to the Crucial T700, which is Micron's first PCIe 5.0 drive. For the cost, I'd say the P5 Plus is a much better deal for now, considering PCIe 5.0 requires other latest and most expensive parts, including CPU and RAM.

Like all PCIe 4.0 NVMe SSD, the Crucial P5 Plus runs a bit warm, so the heatsink version is a welcome update. If you have a host that doesn't have a built-in heatsink, such as a game console, the latter is a better choice.

Excellent performance

Affordable; heatsink version available

PCIe 4.0 support, backward compatible with PCIe Gen 3

Helpful Storage Executive software

5-year warranty


Comparatively modest endurance

Capacities cap at 2TB; runs a bit warm


The Micron Crucial P5 Plus is an excellent NVMe SSD and a better choice than many of its peers, including the rival Samsung 980 PRO, thanks to its significantly more affordable pricing.

The new heatsink version makes the drive an even more versatile option for those needing a built-in cooling solution.

Since the initial reviews some two years ago, I've used multiple units for a long time and can attest to the fact this is a reliable drive that can handle extensive loads day after day with ease.

This is the drive to get if you're looking for a well-performance, feature-laden SSD for your gaming or professional rig. It's an excellent choice for a PCIe 4.0 motherboard but will also work well for those with the latest PCIe 5.0. In this case, it's a great bang for your buck compared to the T700.

  1. Hi, I’m using a P5 for my OS,and P3’s for my storage.They are 2Terabytes, I’m using a X570S Carbon Max MSI AMD Motherboard is this alright for compatibility?

  2. Hello Dong,

    Great article! I really found difficult to find something related to the use of Crucial P5 plus on a PCIe 3.0 board.

    I wanted to ask you some more info about it since I intend to purchase it.
    I have a 10th gen intel with a motherboard that suppoort PCIe 3.0. For what I understood it should not be a problem being the Crucial 5 plus compatible although running at lower speed.

    I was wondering, how about the heat dissipation o the Crucial P5 plus runnning on PCIe 3.0 laptop base? I would use a thermal pad anyway, but in theory, shouldn’t it couse less heat even for heavy workload? Running basically at PCIe 3 speed it should not run hot as its max performance. Could you confirm?

    My mainly use involve softwares like Lightroom, Photoshop, Davinci Resolve, QGIS and ArcGIS. I mainly was interested in the Crucial P5 plus since it has DRAM compared to the Samsung 980. Do you think I would beneft the specs of the crucial or better saving money on the Samsung 980 (base model not PRO).

    Thanks in advance.

    • It’ll work great, Alex, and in fact, better in terms of heat — 4.0 drives are generally hotter when running on a 4.0 machine. I tested it using both PCIe 4.0 and 3.0, as noted on the charts, and I’ve been using it on one of my PCIe 3.0 machines since. I’d go with whichever that’s cheaper.

  3. Hello,
    Just installed this drive and I see it runs somewhat hot (55C in standby,with nothing but background operations). In comparison my older INTEL NVme is at 35C and both of the older 2.5″ SSds at 27C.
    Have not tried a drive-taxing procedure,but wondering if you are finding similar temps in your setup.

    Thanks and thanks for all the great reviews.


    • You can see my drive’s temperature in the screenshot, Dusan. And I was testing it. I’d say that’s quite normal. Temp depends a lot on your environment, too.

      • Apologies, I do see it. My set up is well cooled. I have added the bequiet! Mc1 pro M.2 cooler and the drive now runs at 30-34C. Much happier.


        • No worries, Dusan. I appreciate your input. In fact, thanks to your question, I checked on the drive again just now — in my standard testing, I always use the device for an extended amount of time after the review — and its temperature seemed OK. Yes, it gets warm but not warmer than most other NVMe SSDs, including the Samsung 980 PRO. No, heat is never good but you can’t avoid it. 🙂
