Crucial P2 vs Crucial P5: Which one should you buy?

Intending to get a Crucial NVMe SSD? Stuck in a confusion “Crucial P2 or Crucial P5” which one is better? Investing a few minutes reading the article, will help you get rid out of this confusion.

The Crucial SSDs are reliable and durable but investing in the best is a good decision. After comparing the features and prices of Crucial P2 and Crucial P5 Variants, I have got a clear answer for the question of which one is best between the both.

While P5 is clearly a winner when it comes to the TBW and overall durability, most of the P2 variants are available at comparatively lower price tags. This is the reason why I am here to help you pick the right one.

Both Crucial P2 and Crucial P5 NVMe SSDs include 4 different variants: 250 GB, 500 GB, 1 TB, 2 TB. The Crucial brand hasn’t yet introduced a higher variant other than 2 TB. 

In case, if you’re intending to get a Crucial NVMe SSD just to boost up the speed of the Operating System, then you can rely on 250 GB or 500 GB. Though the higher variants are good enough and get you effective R/W speed, they’re costlier ones.

Check out the Read/Write for different variants of Crucial P2 and Crucial 5 NVMe SSDs. Here, the read speed of the Crucial P5 NVMe SSDs is the same “3,400 MB/s” for all the variants. Whereas, in Crucial P2 NVMe SSD the Read Speed increases depending on higher variants.

The Crucial P2 is a DRAM-Less SSD. But, since its having the HMB (Host Memory Buffer), it can use the main system’s memory for caching purposes.

While the P5 has a faster DRAM cache which makes it really fast. The speed of both SSDs is different (i.e. Speed = P2<P5) even though both are working on the same x4 lanes of PCIe 3.0

Let’s compare both of them below.

Read/Write Speed of Crucial P2 NVMe SSDs

By referring to the table above, we can say that the read speed of lower storage variants of Crucial P2 is slower than the higher variants. Also, the write speed of the 250GB variant is just 1150MB/s while the write speed of the 2TB variant is 1900MB/s.

Read/Write Speed of Crucial P5 NVMe SSDs

With this table, we can see that the Crucial P5 has the same read speed i.e. 3400MB/s on its all storage variants. While the write speed is lower with the 250GB and highest at the 2TB model. But, it is still way better than the Crucial P2.

As you can see above the slab, it indicates that Crucial P5 NVMe SSDs are dominating the R/W speed of Crucial P2 NVMe SSDs.

So, if you are looking for an SSD with a better good read/write speed, P5 should be your pick. But, if you are good with around 1000MB/s write speed and 2000MB/s read speed, you can go with the Crucial P2 as well.

Crucial P5 NVMe SSDs (2TB) Read: 3,400 MB/s |Write: 3,000 MB/s

Comparing the IOPS R/W speed of different variants “Crucial P2 vs Crucial P5” it’s understandable that Crucial P5 NVMe SSDs is a reliable one.

Read/Write Speed of Crucial P5 NVMe SSDs

With this comparison, it is clear that the P5 has a better ability to process random requests. Hence, it can perform better when it comes to random read/write. The 500GB, 1TB, and 2TB variants of Crucial P5 dominates this niche with a massive 500,000 IOPS speed.

It’s better to know the TBW of an SSD before investing in it. Terabytes Written indicate the lifespan of the Solid-State Drive. I have stated the TBW for each variant of Crucial P2 and Crucial P5 NVMe SSDs. Have a look at it.

Comparing both the Crucial NVMe SSDs, it’s pretty clear that Crucial P5 SSDs are better than Crucial P2. The TBW of Crucial P2 Solid-State Drives is half of Crucial P5 SSDs. Hence, Crucial P5 SSDs are a more durable and better choice to invest in when it comes to endurance.

5. Price Difference between P2 and P5

Considering the Price, Crucial P5 SSDs are a bit more expensive compared to Crucial P2. There is no such huge difference as “Few bucks more” but you can gain effective Read/Write Speed and a durable SSD with a long lifespan.
