About this deal

Speaking of which, while the P1 leveraged a Silicon Motion SM2263EN NVMe controller and the P2 used Phison’s E13T, Crucial’s P5 features the company’s first, and quite beastly, consumer NVMe SSD controller. The controller interfaces with the host over a PCIe 3.0 x4 link and communicates via the NVMe 1.3 protocol. The DRAM cache size on the 250GB and 500GB drives is 512MB, the 1TB drive uses 1GB and the 2TB model uses 2GB. The largest function of the DRAM is to actually manage memory mapping in real time, so not a lot of user data is ever stored there. The amount of user data stored in the cache at any point in time is usually only 1-2 MB and the rest is used for a live copy of the logical and physical translation table.

Some of the storage capacity is used for formatting and other purposes and is not available for data storage. 1GB equals 1 billion bytes. Not all capacities available at initial launch. Here is promotional video for the Crucial P5 M.2 2280 NVMe SSD series before we look at the test system and get to the benchmarks! Article Contents There are a few reasons as to why Micron’s flash is some of the most responsive besides access to four planes per die. This floating gate NAND design is a bit more robust than charge trap designs as it has a lower charge spread which results in less read errors and ECC intervention as well, it has better data retention because of a more stable charge. Micron’s flash also features a tile-based floorplan design that is integrated with the CMOS under Array circuitry for better space efficiency and provides redundancy of elements within the tiles to allow for greater defect tolerance.The Crucial P5 is the first SSD based on Micron's new in-house controller DM01B2, which is an 8-channel design with DRAM support. Crucial P5 comes in the M.2 form factor, using a fast PCI-Express x4 3.0 NVMe connection to interface with the rest of the system. As expected, the 96-layer TLC NAND flash chips on the Crucial P5 are made by Micron.

That may be so for sequential but the Force series does not have the highest random read/write speeds out there... And, since the R5s on SSDs typically operate somewhere around 500-700MHz, we believe Crucial’s newest NVMe controller’s operating speed isn’t too far off. The M3 cores can operate at up to 200MHz and has dynamic power modes, so you can see that while there are so many, they are very efficient.Part-specific certification of how this product meets the requirements of the current DIRECTIVE 2011/65/EU and 2015/863/EU, a.k.a. Restriction of Hazardous Substances (RoHS) Directive (Recast).

When Crucial introduced the P1 M.2 NVMe SSD series in 2018 they entered the consumer NVMe drive market with one of first highly-anticipated QLC NAND Flash drives. Crucial had the entry-level NVMe market covered with the P1 series, but did not have a high-end NVMe solution for those wanting a premium storage drive for their laptop or desktop PC. No one knew it at the time, but it would be another 1.5 years for Crucial to launch a high-performance NVMe SSD.Performance for all the capacities is 3400 MB/s read, but the 500GB, 1TB and 2TB drives are rated at 3000 MB/s write with the smallest 250GB model being rated at 1400 MB/s write. The drive also features Integrated Power Loss Immunity, but the SLC caching helps in many cases, too. The Dynamic Write Acceleration (SLC cache) works a little bit differently than most SLC caches we have come across in the past – Crucial built some new tech into the P5.
