The P1 comes in a small, blue box. While there aren't a lot of technical details, the packaging advertises some of the drive's key features including its 1TB capacity, support for NVMe, and 5 year warranty. The back of the box also has a small window that lets you see the drive and view the QR code on it. Inside, you'll find the P1 as well as a small guide with information on where you can get additional help and download the migration and cloning software.
The P1 uses the 2280 form factor for M.2 (NGFF) SSDs. It measures 22 x 80 x 2.2 mm and weighs less than 10g. The drive also has an "M key" edge connector which provides PCIe SSDs with up to 4x lanes of bandwidth.
The P1 is one of the first drives to use Silicon Motion's new SM2263EN controller. Designed for cost-effective, small form factor SSDs, this 4 channel, PCIe Gen 3 x4 SSD controller is powered by a dual ARM Cortex CPU and offers support for 3D NAND from all the major suppliers. The SM2263EN also employs Silicon Motion's proprietary NANDXtend error-correcting code (ECC) technology to enhance the endurance and retention of 3D NAND and provide comprehensive data protection.
It's hard to see in these photos, but there is a small, green LED near the M.2 connector that flashes when the P1 is being accessed.
For the 1TB version of the P1, Crucial opted to use Micron's QLC 64-layer 3D NAND flash. Looking at the picture above, you can see that there are 512GB NAND flash packages on the top of the PCB. The drive also has a single 1GB Micron DDR3L SDRAM memory chip that is used for caching.
