The Crucial P3 Plus 1TB comes with no heatsink from the factory. Instead, you will get a sticker, as shown in our photo above. Cooling will depend on the heatsink that comes with your motherboard, or you can pick up a SilverStone TP05.
The Crucial P3 Plus 1TB is an M.2 2280 format SSD. If you are not familiar with the M.2 physical standard, M.2 2280 means it the size of the drive is 22mm by 80mm, hence its numerical designation. Its components are located on the black printed circuit board located behind the branding sticker, which we will take a closer look at in just a moment. The Crucial P3 Plus 1TB works on the NVMe 1.4 logical device interface and plugs into compatible motherboards directly. Electrically, M.2 NVMe interfaces with PCIe 4.0. The P3 Plus uses four lanes for up to 8000MB/s bandwidth in each direction.
Flipping the Crucial P3 Plus 1TB around and you will find no components of interest. The labels on this side of the Crucial P3 Plus SSD carries miscellaneous information such as its model name, capacity, serial number, and regulatory certifications. Other than that, it is completely blank as all the components are located on the other side. This SSD is assembled in Mexico, which is something I have not seen before.
Peeling the sticker back, and you can see what the Crucial P3 Plus 1TB is made from. There are two different components that can be seen. At the heart of Crucial's P3 Plus 1TB is a Phison PS5021-E21. It is an NVMe solution on the M.2 socket to utilize the bandwidth afforded by the PCIe 4.0 standard. There is no native encryption support. To save cost, no DRAM is available to the controller for system memory. Just for background, SSD DRAM is used as a cache for writing data to the drive and storing a table that maps where each logical block address is physically located on the NAND flash memory. However, DRAM chips are not cheap even if you only need 1GB of DRAM per 1TB of storage, so budget SSDs often omit it to cut cost. Instead, DRAM-less SSDs store the mapping data on the NAND flash itself, which affects performance, as flash memory is orders of magnitudes slower than DRAM. To compensate, the NVMe interface supports something called the Host Memory Buffer, which allows the use of some of your computer's RAM to cache the mapping data. This is not as fast as an SSD having its own DRAM, but still much faster than the SSD's NAND flash memory.
The Crucial P3 Plus's flash memory are Micron-branded 176-layer quad-level cells in two chips labeled NY161. Its rated write endurance is rather low at 220TBW, which equates to about 120GB per day for five years. This is significantly lower than the WD_BLACK SN770 NVMe SSD 1TB and Crucial P5 Plus 1TB at 600TBW. The XPG Atom 50 1TB is rated even higher at 650TBW. The Crucial P3 Plus 1TB's rated power consumption is not published. 24GB out of the 1024GB total capacity -- just under 3% -- is provisioned for the drive controller for overhead, so the actual usable space is 1TB, as advertised. You will see 931GB in Windows.
Specified at 5000MB/s read and 3600MB/s write over NVMe 1.4 on PCIe 4.0 x4, these figures are modest for a PCIe 4.0-based budget model. No IOPS ratings are available. That said, it is about one-and-a-half times as fast as many PCIe 3.0-based drives. To see how all this hardware translates to numbers in our benchmarks, we will pit the P3 Plus 1TB against the big boys of this game to see how this new budget PCIe 4.0-based drive from Crucial steps up against some popular NVMe-based SSDs from manufacturers like Kingston, Patriot, Western Digital, XPG, and even Crucial themselves in the next seven pages or so.
