The reason for this is not least the technical superiority of the Samsung SSDs, especially this Crucial P1 in the M.2 format with 500 GB capacity, with stacked QLC memory cells with multiple layers - called 3D-NAND -, very fast PCI Express 3.0 connection with 4 lanes and support for the state-of-the-art NVM Express protocol.
An overview of the Crucial P1 M.2 NVMe PCIe SSD:
- Modern M.2 NVMe PCIe SSD with 500 GB capacity and 512 MB cache
- Extreme fast 1,900 / 950 MB / s read / write
- Total 90,000 / 220,000 IOPS 4KB Random Read / Write
- Silicon Motion SM2263EN Controller & Micron 4-Bit 3D NAND QLC
- Lifetime (MTBF): 1.5 million hours
- Exclusively in M.2 format due to rapid PCIe 3.0 x4 connection
For the first time, Samsung's PM981er SSD series will only be available in M.2 format, 2280 mm (22 mm wide, 80 mm long), and will be connected via PCI Express 3.0 with 4 data lines. The classic 2.5-inch format has thus come of age, as its comparatively slow SATA-6G interface can no longer compete with the explosive increase in performance of modern SSDs due to its severe bandwidth limitation (maximum net data rate of around 550 MB / s). If you want to profit from the enormous speed potential of the Crucial P1, you must upgrade in case of doubt or use a PCI Express adapter card, which of course can be found at any time in the Caseking shop via the search function.
Highly efficient Micro SLC 3D NAND
In the case of the Micron 3D-NAND QLC of the Crucial P1, the memory cells are cylindrically stacked in 64 layers. As a result, on the one hand, larger storage volumes with a higher reading and writing speed are possible with a smaller area of the storage blocks, on the other hand the service life of the storage is increased and the energy efficiency is improved.
M.2 NVMe PCIe SSD with brute read and write speed
This hyper-fast drive's silicon motion controller supports four standard 3.0 PCI Express lanes, providing a theoretical maximum of approximately 3,900 MB / s! In conjunction with the built-in Micron 3D NAND QLC, the 500 GB version of the Crucial P1 reaches 1,900 MB / s for reading and 950 MB / s for writing, as well as IOPS values of 90,000 in 4KB read and 220,000 in 4KB write. Silicon Motion's advanced SM2263EN controller chip also reduces waste heat and pre-empts with high-temperature performance throttling.
Support for the NVM Express protocol for PCIe SSDs
In addition, this Crucial SSD P1 also supports the NVM Express protocol (NVMe for short), which was specially developed for modern PCI Express SSDs. This replaces the old AHCI protocol, which dates back to before the widespread adoption of SSDs and is not optimized for highly parallelized disk accesses. NVMe provides significantly lower latencies, as well as multiple and lower command queues, which translate into significantly more performance in non-linear transfers such as 4K read / write.
