What’s the difference between Crucial P1, P2 and P5?

The P5 is the latest version of Crucial’s NVMe M.2 Solid State Drive series. So, how does the new product stack up against the older P1 and P2 versions?

You can find out in this comparison guide between the three SSDs.

Quick Summary

The newer Crucial P5 NVMe M.2 SSD is substantially faster than the Crucial P1 NVMe M.2 SSD and Crucial P2 NVMe M.2 SSD when it comes to sequential read and write speeds.

Not to mention that the P5 is also a lot more durable than the older solid state drives with much higher Mean Time to Failure (MTTF) and TWB (Terabytes Written).

Needless to say, the Crucial P5 is the best option out of the group.

Maximum Sequential Read Speed

At 3400 MB per second, the Crucial P5 NVMe M.2 SSD has a much faster maximum sequential read speed when compared to the Crucial P1 NVMe M.2 SSD (which tops out at 2000 MB per second) and Crucial P2 NVMe M.2 SSD (which has a max of 2400 MB per second).

In some cases, the read speeds depend on the model number. You can find the complete list of maximum sequential read speeds below:

• 500 GB P1: 1900 MB per second
• 1 TB P1: 2000 MB per second
• 2 TB P1: 2000 MB per second

• 250 GB P2: 2100 MB per second
• 500 GB P2: 2300 MB per second
• 1 TB P2: 2400 MB per second
• 2 TB P2: 2400 MB per second

• 250 GB P5: 3400 MB per second
• 500 GB P5: 3400 MB per second
• 1 TB P5: 3400 MB per second
• 2 TB P5: 3400 MB per second

Maximum Sequential Write Speed

At up to 3000 MB per second when it comes to maximum sequential write speed, the Crucial P5 NVMe M.2 Solid State Drive also has a major advantage over the Crucial P1 NVMe M.2 Solid State Drive (which has a maximum of 1700 MB per second) and Crucial P2 NVMe M.2 Solid State Drive (topping out at 1900 MB per second).

You can check out the full list of sequential write speeds below:

• 500 GB P1: 950 MB per second
• 1 TB P1: 1700 MB per second
• 2 TB P1: 1700 MB per second

• 250 GB P2: 1150 MB per second
• 500 GB P2: 940 MB per second
• 1 TB P2: 1800 MB per second
• 2 TB P2: 1900 MB per second

• 250 GB P5: 1400 MB per second
• 500 GB P5: 3000 MB per second
• 1 TB P5: 3000 MB per second
• 2 TB P5: 3000 MB per second

Mean Time to Failure

The mean time to failure (or MTTF) measures the average length a solid state drive is expected to last in between hardware failures.

The Crucial P5 NVMe M.2 SSD is the best out of this group with a MTTF of 1.8 million hours.

In comparison, both the Crucial P1 NVMe M.2 SSD and Crucial P2 NVMe M.2 SSD have a MTTF of 1.5 million hours.

Terabytes Written

Another durability metric is terabytes written (or TBW), which measures how much data can be written on the SSD before the drive is likely to fail.

The Crucial P5 is once again the big winner when you compared it to similar size options of the Crucial P1 and Crucial P2.

The TBW is based on specific models. You can find the specs for each below:

• 500 GB Crucial P1 NVMe M.2 SSD: 100 TB
• 1 TB Crucial P1 NVMe M.2 SSD: 200 TB
• 2 TB Crucial P1 NVMe M.2 SSD: 400 TB

• 250 GB Crucial P2 NVMe M.2 SSD: 150 TB
• 500 GB Crucial P2 NVMe M.2 SSD: 150 TB
• 1 TB Crucial P2 NVMe M.2 SSD: 300 TB
• 2 TB Crucial P2 NVMe M.2 SSD: 600 TB

• 250 GB P5: 150 TB
• 500 GB P5: 300 TB
• 1 TB P5: 600 TB
• 2 TB P5: 1200 TB

Data Transfer Software

All three products use the Acronis True Image for Crucial to transfer data.

Operating Temperature

The solid state drives have an operating temperature range of 0°C to 70°C (or -32°F to 158°F)

Warranty
