Result and general impression …
The Crucial P1 1TB M.2 NVMe SSD CT1000P1SSD8 impresses with enormously high sequential read and write rates and even almost reaches the top of our SSD charts in some benchmarks despite its low price.
As we could clearly show in the test, the P1 1TB M.2 NVMe can beat its SATA counterparts in almost all benchmarks, which means that the new Micron 64 Layer 3D QLC NAND in Crucials first NVMe PCIe SSD can definitely convince in contrast to the 3D TLC NAND of the MX500 SATA SSD.
In addition, the Crucial P1 offers a power failure protection to increase data security, but no AES encryption like the Crucial MX500 SATA SSD counterparts.
The Crucial P1 1TB M.2 NVMe SSD is specified with 200 TBW (total/tera bytes written), which corresponds to approximately 109 GB per day over a period of 5 years. These specifications are not only important for the warranty (Crucial now gives a limited 5-year warranty), but also speak for the high durability of the NAND cells. If you want to know more about TBW, you will find numerous data and formulas at Micron and in the JEDEC SSD specifications.
All in all, the first NVMe PCIe SSD from Crucial with the new 3D QLC technology in combination with the large cache convinced us and is an excellent alternative to the M.2 SATA version at an equally low price.
