The SAMSUNG SSD PM851 mSATA 256GB is a solid-state drive (SSD) from Samsung that is designed for use in more compact devices such as laptops, ultrabooks, and small desktop PCs. This mSATA SSD offers the benefits of solid-state technology in a compact form factor that is ideal for devices where space is limited. Here is a detailed description of the technical details, features and application areas of the Samsung SSD PM851 mSATA 256GB:
Technical Details
1. Capacity:
- 256 GB: The SSD offers a storage capacity of 256 gigabytes. This capacity is suitable for most modern operating systems, applications and a moderate amount of user data.
2. Form Factor:
- mSATA: The form factor of the SSD is mSATA (mini-SATA), which is much more compact than the traditional 2.5-inch form factor. This makes the PM851 ideal for use in devices where space is limited, such as ultrabooks or small desktop PCs.
3. Interface:
- SATA III (6 Gb/s): The SSD uses the SATA III interface, which enables a maximum data transfer rate of up to 6 gigabits per second (750 MB/s). This interface is compatible with most modern computers and laptops.
4. Storage technology:
- 3D NAND Flash: The PM851 uses 3D NAND Flash technology, which offers higher storage density and better performance compared to traditional 2D NAND technology. 3D NAND makes it possible to pack more memory cells on a chip while improving reliability.
5. Controller:
- Proprietary Controller: The SSD uses a Samsung-developed controller optimized for the needs of mSATA SSDs. This controller ensures high performance and efficient processing of data.
6. Performance:
- Sequential Read/Write Speed: The SSD offers sequential read and write speeds of up to approximately 540 MB/s for reading and 470 MB/s for writing. These speeds ensure fast data transfer and system response.
- Random IOPS (Input/Output Operations Per Second): The SSD offers up to 75,000 IOPS in random read and up to 60,000 IOPS in random write, which is high performance for most modern applications.
7. Cache:
- DRAM Cache: The PM851 features a DRAM cache that improves performance by caching frequently accessed data. The size of the cache can vary, but is typically on the order of 256 MB.
8. Power Consumption:
- Power Consumption: The SSD is energy efficient, with typical power consumption of around 2 to 3 watts in operation and even lower values ​​in standby mode, making it suitable for use in mobile devices.
9. Lifespan:
- MTBF (Mean Time Between Failures): The SSD is designed for a long lifespan, with MTBF values ​​often over 1 million hours, making it reliable for continuous operation.
10. Error Correction:
- ECC (Error Correction Code): The SSD uses error correction mechanisms to ensure the integrity of the stored data and minimize the impact of read errors.
Features
1. High Performance:
- Fast Data Transfer Rates: The mSATA SSD offers high sequential read and write speeds, ensuring fast data transfers and system response.
2. Compact Design:
- mSATA Form Factor: The compact mSATA form factor allows the SSD to be integrated into devices where space is limited, such as Ultrabooks and small PCs.
3. Energy Efficiency:
- Low Power Consumption: The SSD offers high energy efficiency, making it ideal for mobile devices where long battery life is important.
4. Reliability:
- Robust Design: The PM851 is designed for high reliability and long life, with advanced error correction and a rugged construction.
5. Improved Data Integrity:
- Error Correction: The SSD uses ECC to ensure data integrity and improve reliability.
