There is a year and a half between the release date of the Crucial P1 at the end of 2018 and the release of the Crucial P1 in spring 2020. But even if the name might suggest it, the second one is not necessarily a direct successor. What are the differences between the Crucial P1 and the Crucial P2 in direct comparison? For which user type is one or the other M.2 NVMe SSD the right choice?

Differences of Crucial P2 and Crucial P1
Form factor and power
Both the Crucial P1 and the Crucial P2 are NVMe SSD hard disks in M.2 plug-in card format. As interface both drives use the fast PCIe Gen 3.0 interface in the full expansion with the 4 data paths. The physical dimensions correspond to the 2280 quasi-standard among the M.2 SSDs with a width of 22 millimeters and a length of 80 millimeters. The performance of the P1 and P2 is on a similar level, so the differences should not be noticeable in everyday operation.
Storage capacity and memory type
The first big difference between the Crucial P2 and the Crucial P1 is the memory sizes offered. While the P1 is available in three capacities of 500 GB, 1 TB and 2 TB, the P2 is limited to a 250 GB and a 500 GB version. Secondly, the SSD siblings use different types of flash memory. In the Crucial P1, the manufacturer uses the less expensive 4-bit QLC NAND, but in the Crucial P2 it uses the more durable 3-bit TLC memory cells.
Warranty and features
With the warranty period of 5 years, the NVMe SSDs from Crucial are similar. Whereby the amount of written data allowed in this time has increased by 50 percent to 150 TB for the P2 compared to the P1 using the 500 GB version as an example. The manufacturer has remained true to itself in terms of the scope of delivery and included a license for the cloning software from Acronis with the two M.2 SSD drives, which should make data migration from an existing hard drive easier.
Conclusion SSD comparison – Crucial P1 and Crucial P2 differences
The Crucial P2 is not really to be seen as a successor to the Crucial P1, but neither is it a competitor. Rather the two M.2 SSDs from Crucial complement each other in the portfolio. Already the different storage capacities offered can make the decision easier. The Crucial P2 allows thanks to the small 250 GB variant a particularly inexpensive entrance with the NVMe SSD drives. Due to the more inexpensive QLC memory, the Crucial P1 tends to be less expensive than the P2. The small differences in performance should not be noticeable in everyday operation, so you can decide on the Crucial P2 or the Crucial P1 based on the required memory size and also the current availability.

Can I use a Crucial P1 1TB NVMe SSD to Upgrade my 11″ early 2015 MacBook Air (currently on 250GB)? Do I need a Sintech NGFF PCle SSD Adapter card as well?
Hello PERCY JAL CHIBBER,
as I understand, you will need an extra adapter to upgrade your MacBook Air 2015 with an ordinary M.2 NVMe SSD, because Apple was using proprietary slot to connect storage.

Como estas seguro que la memoria nand del p2 es TLC?
Hola Manuel,
Desafortunadamente los datos técnicos del sitio web de Crucial no están completos. Pero todas las fuentes confiables reportan que el Crucial P2 usa la memoria TLC NAND.
Muchos saludos

Can i use a P2 instead of P1, really can not find available P1. Motherboard is MSI B450-TOMAHAWK.
Thanks in advance
Hello Joel,
sure, you can use P2 instead of P1, both SSD need the same requirements. As I see it, the motherboard has an M.2 slot that fits any M.2 NVMe SSD with PCIe interface.
