Micron Releases the P1 NVMe QLC Solid State Drive
Crucial, the consumer brand of Micron Technology for memory
and storage upgrades, today announced the availability of the Crucial P1 SSD, a PC storage device that leverages the NVMe PCIe interface and Micron's QLC technology.
PCMark 8 benchmarks show that the drive is capable of mixed-mode throughputs of up to 565MB/s, with a composite score of 5,084. The drive delives sequential read/write speeds up to 2,000/1,700 MB/s, using a hybrid-dynamic write acceleration, an SLC cache implementation. The SSD is based on Silicon Motion's entry-level SM2263 controller. All data written to the Crucial P1 hits the SLC cache first, and is compacted into QLC blocks only when the drive's free space starts running low. This means that a mostly-empty drive will be using tens or hundreds of GB of SLC, but as it fills up the cache will shrink down to just 5-24GB depending on the model.
The drive offers an MTTF of 1.8 million hours and an endurance of up to 200TB total bytes written, with power usage at an active average of 100mW.

Available in capacities up to 1TB, and backed by a five-year limited warranty, the Crucial P1 SSD leverages Micron quad-level cell (QLC) NAND technology.
By storing four bits in each NAND cell, QLC NAND narrows the affordability gap between hard drives and flash storage, enabling increased speeds and capacities at a more affordable price point.
The drive comes bundled with the Crucial SSD Install Guide and the Acronis True Image HD software for easy migration of data. The Crucial Storage Executive software tool allows users to see how much storage (GB) they've used, download the latest firmware, and improve drive performance.
The P1 SSD also offers data loss protection via the Multistep Data Integrity Algorithm; protection from overheating via Adaptive Thermal Monitoring tools; faster writes via Hybrid-Dynamic Write Acceleration technology and data protection at the component level via Redundant Array of Independent NAND.
The initial MSRPs for the Crucial P1 are more expensive than the Intel 660p, and about matches some of the most affordable high-end NVMe drives.
The 2TB model will be launching slightly later due to using DDR4 DRAM instead of the DDR3 used by the 500GB and 1TB models.
