Crucial P1 vs Crucial P2: How to choose the right one?

Both Crucial P1 and Crucial P2 are nearly similar to each other in all aspects. But, is there any difference in both? Is there anything that you should keep in mind before buying any of these? Honestly, there are a lot of differences between these devices?

If we look closely at the features, you will see that the P1 beats the P2 in most of the terms. But, just because the P2 seems to be the latest product, it is not ahead of its predecessor i.e. P1. In this article, we are going to uncover some of the main differences between these both.

We will compare the theoretical specs as well as the benchmark scores. So, keep reading until the end.

Before proceeding further, it is worth knowing the basic offerings of these SSDs promised by the manufacturer. This would help us have a basic idea of both the products.

As per these specs, you can see that the Crucial P2 is capable of offering a better sequential read/write speed. But, would it win in the actual benchmark tests too? That is the main question.

The benchmarks are done using CrystalDisk software. The system was using an Intel i5 8th Gen processor along with a 3200Mhz RAM. The results may vary depending on your system configurations and the overall space occupied.

SpeedCrucial P1 1TB (100% Empty)Crucial P2 1TB (100% Empty)
Sequential Read (Avg.)1578 MB/s1975 MB/s
Sequential Write (Avg.)1269 MB/s1793 MB/s
4kB Random Read (Avg.)78.2 MB/s54.1 MB/s
4kB Random Write (Avg.)174.4 MB/s132.8 MB/s

With these results, you can clearly see that the Crucial P2 is winning when it comes to sequential data reading and writing. This might be happening because of more layers of 3D QLC NAND. But, if we talk about the random operations, the P1 is winning the game clearly because of its faster DRAM cache.

Both P1 and P2 are very popular products in the SSD sphere. But, people who are aware of the importance of DRAM cache would surely choose the P1 over P2. However, people who just want a good sequential read/write speed would go for the P2.

If we look at Amazon.com, the P2 has 9,175 unique reviews with a full 5-Star rating by the time I am writing this article. 87% of the total buyers game this SSD 5 out of 5 stars.

The P1 is leading here with 11,850 unique users reviews with a full 5-star rating. 89% of the total buyers of this SSD gave it 5 out of 5 stars.

The same is happening on other platforms like NewEgg. Because of its stable random read/write operations, the Crucial P1 always beats the P2.

Let’s see what the company has to say about the endurance of these products.

Crucial P1Up to 400 TBW5-Years1.8 Million Hours
Crucial P2Up to 600 TBW5-Years1.5 Million Hours

With this, you can say that the P1 can give you better results in the longer run. However, for larger data reading and writing operations, the P2 is a good choice.

Crucial P2 has slightly better features if we talk about raw storage. However, the P1 is great in terms of cache handling.

When we compare the prices of both these SSDs, you would see that the P1 would be priced around 10-20% higher than the P2. You can check the current prices below.

In my opinion, both the SSDs are good but in their own specific terms.

In other words, the Crucial P2 is a perfect option for those who generally move large files from one place to another inside their systems. The sequential read and write speed is comparatively the best in P2.

But, the Crucial P1 will beat the P2 when it comes to the random read/write operations. For example, if you launch any software, the P1 is always capable of opening it at a faster pace. The same goes with the system rebooting.

So, if you just want an SSD to enhance the performance of your system and reduce the software/OS loading times drastically, just go for the P1. But, if you just want to increase the read/write speed of huge files, P2 is suitable for you.
