Everybody forgets things occasionally! Back in September, Patrick sent me a bunch of drives to benchmark and review. Between the SSD buyers guide and some other content I was working on at the time, I managed to forget to review one of the drives I was sent. These recently became a topic because the pricing has been very low on Amazon (Affiliate Link) often at prices less than mid-range PCIe Gen3 SSDs. As a result, today we are looking at the Crucial P3 Plus 1TB SSD. The Crucial P3 Plus is Crucial’s entry-level PCIe 4.0 SSD, and exists between the base model P3 (which I also received but forgot to review!) and the P5 Plus. Patrick ended up acquiring a small collection of P3 Plus drives for the Asustor Flashstor 6 FS6706T NAS, so we thought it would be good to dust off my old benchmarks and post a review.
Crucial P3 Plus 1TB NVMe SSD
The Crucial P3 Plus 1TB comes in a single-sided M.2 2280 (80mm) form factor.
The Crucial P3 Plus uses a Phison E21T controller, which is paired with their 176-layer QLC flash. There is no DRAM cache on this drive, as one might expect given the more budget-oriented market positioning of this drive.
The back of the P3 Plus only contains regulatory markings and a label.
Crucial P3 Plus SSD Specs
The P3 Plus line of SSDs is available in sizes between 512GB and 4TB.
The Crucial P3 Plus we have today is the 1TB model. Sequential read speed is quoted at 5000 MB/s, with write speed at 3600 MB/s. As far as PCIe Gen 4 SSDs go, these are not particularly impressive specifications, but at least the read speed clearly exceeds what can be achieved by a Gen 3 drives.
Endurance is very poor 220 TBW. I consider the satisfactory line as 600 TBW for a 1TB drive, so the P3 Plus is quite a ways off from that. This is a QLC-based drive, which is likely what is contributing to the low-rated endurance. The warranty is the industry-standard 5 years, which is good to see.
CrystalDiskInfo can give us some basic information about the SSD and confirms we are operating at PCIe 4.0 x4 speeds using NVMe 1.4.
Test System Configuration
We are using the following configuration for this test:
- Motherboard: ASUS PRIME X570-P
- CPU: AMD Ryzen 9 5900X (12C/24T)
- RAM: 2x 16GB DDR4-3200 UDIMMs
Our testing uses the Crucial P3 Plus 1TB as the boot drive for the system, installed in the M.2_1 slot on the motherboard. The drive is filled to 85% capacity with data and then some is deleted, leaving around 60% used space on the volume.
Next, we are going to get into our performance testing.
