Crucial P5 Plus PCIe 4.0 NVMe M.2 SSD Review

If there is anything we have learned about Micron/Crucial over the years, it is that they like to sit in the weeds.  Never really being the first to jump out with a new product, the Crucial norm is to slip a product into the market once the market has become comfortable at that level.  When considering the success Crucial/Micron has had over the years, we have always found this to be an unusual position.  This is especially so as of late with the success of Micron’s newest 176-layer TLC NAND flash memory which is being scooped up for some of the best SSDs around.

On our test Bench today is Crucial’s first PCIe 4.0 NVMe SSD release, the P5 Plus Gen4 NVMe SSD.  Let’s add to that by acknowledging that this SSD also contains Micron’s first proprietary PCIe 4.0 NVMe SSD controller.  And you can bet it also contains some choice Micron 176-layer TLC NAND flash memory as well.


The Crucial P5 Plus is a PCIe 4.0 2280 (80mm) form factor M.2 SSD that is available in capacities of 500GB, one and two terabyte.  It’s performance is listed at 6.6GB/s read and 5GB/s write with up to 630K IOPS read and 700K IOPS write for the 1TB version we are testing today, and a bit of a boost to 720K read IOPS for the 2TB capacity drive.


The Crucial P5 Plus is a single-sided SSD that contains two packages of Micron’s hand picked 176-layer TLC NAND flash memory, Micron’s own proprietary PCIe 4.- NVMe SSD controller, along with one piece of Samsung DDR4 DRAM cache.


The P5 Plus comes with a 5-year limited warranty and has an endurance rating of 600TBW for the 1TB capacity which doubles for the 2TB version.  A quick check of Amazon shows pricing of the Crucial p5 Plus at $107.99 (500GB), $179.99 (1TB) and $367.99 (2TB) which makes this one of the best value Gen4 SSDs available.


Crucial also provides an excellent SSD monitoring and maintenance tool called the Crucial Storage Executive which is available FREE from this link. This tool can assist with a wealth of tasks as shown in the menu of this picture below.
