The Reletech P600 M2 SSD features a PCIe 3.0×4 bus type, which provides high-speed data transfer and improved compatibility with older systems. 2 2280 Interface Type. The Reletech P600 M2 SSD has an M. 2 2280 interface type, which is widely used in laptops and desktops for easy installation and compatibility. TLC NAND flash type. With NVMe transport protocol, this SSD can deliver faster data transfer speeds and improved system responsiveness. The Reletech P600 M2 SSD has a PCIe 3.0×4 bus type, which allows for faster data transfer and improved power efficiency. 2 2280 interface type ensures compatibility with a wide range of devices, making it a versatile option for upgrading your system’s storage. The Graphene cooling fin ensures that the SSD stays cool and operates efficiently even during intense workloads. Caching Type: 3D NAND. 512GB : Read (max) up to 3,300MB/s / Write max. Up to 2,300MB/s. 1TB:Read (max) up to 3,400MB/s / Write max. Up to 2,900MB/s. 2TB:Read (max) up to 3,400MB/s / Write max. Up to 2,900MB/s The speed test is based on the 64-bit version of CrystalDiskMark 6.0, 1GB range, which will fluctuate depending on the configuration, for reference only. Mean Time Between Failure (MTBF): 1,500,000 hours. Flash memory vendors are using decimal arithmetic:1MB = 1000KB, 1G = 1000MB calculated, the operating system using binary arithmetic:1MB = 1024KB, 1GB = 1024MB; so such as there are some differences between display capacity and nominal capacity of flash memory product 32gb is about 28.8gb; 64gb is about 59.5gb; 128gb is about 119gb As we are factory and we use 1000KB=1MB for easy calculate, also we use a little space as the Bad Bolck Management software for SSD’s stable using, the real capacity will be: Capacity x 0.93. About reading and writing speed. The actual speed will be directly affected by the configuration of the computer, theformat of the U disk/hard disk, the size and type of the copied files, and the number of files copied at the same time. Therefore, The speed of the U disk/hard disk is different under different usage conditions inactual use, which is a normal phenomenon and not a quality problem!
